Allocation of Resources Without Limits or Throttling
AWS API MCP Server 0.2.13-1.3.46 Init Failure Bypass
CVE-2026-16584
7 - High
- July 23, 2026
Improper handling of an initialization failure in AWS API MCP Server from 0.2.13 through 1.3.46 might allow an actor to bypass the user-configured security policy and execute AWS API operations that the policy was set to deny or gate. When initialization of the security policy enforcement data fails at server startup, the policy check is skipped for the lifetime of the process. IAM permissions on the configured credentials remain in effect and are unaffected. To remediate this issue, users should upgrade to version 1.3.47.
Non-exit on Failed Initialization
s2n-tls <1.7.6 QUIC HRS memory leak via s2n_alloc
CVE-2026-16318
5.3 - Medium
- July 21, 2026
The QUIC transport parameters extension handler in s2n-tls incorrectly uses s2n_alloc instead of s2n_realloc to store the peer's transport parameters. When a TLS 1.3 connection goes through a HelloRetryRequest, the handler is called twice on the same connection. On the second call, s2n_alloc zeroes the existing pointer before allocating new memory, causing the first allocation to be leaked. This can occur during normal QUIC traffic when a client offers a key share group the server does not prefer. An unauthenticated user can amplify the issue by deliberately forcing HelloRetryRequests, causing up to approximately 64 KB of unreachable memory per handshake. Over time, this can lead to increased memory consumption on long-running server processes. The unreachable memory is only reclaimed when the process is restarted. Only server-side QUIC-enabled deployments are affected. Non-QUIC TLS connections are not affected. We recommend you upgrade s2n-tls to version v1.7.6
Memory Leak
s2n-tls before 1.7.6: TLS1.3 Content Type bypass MITM Silent Record Drop
CVE-2026-16317
6.5 - Medium
- July 21, 2026
Missing validation of the outer content_type byte on TLS 1.3 encrypted records in s2n-tls allows an active man-in-the-middle to silently discard individual application data records without either endpoint detecting the modification. RFC 8446 Section 5.2 requires that the outer content_type of all encrypted TLS 1.3 records must be application_data (0x17). The s2n-tls AEAD implementation hardcodes this value in the additional authenticated data rather than using the actual wire byte, so the outer content_type is not covered by the authentication tag. This enables selective suppression of application data. In HTTP pipelining scenarios, dropping a TLS record containing an HTTP request can cause request/response desynchronization, where subsequent responses are delivered to the wrong requests. In write-heavy workloads, a dropped record containing a write request can result in undetectable data loss when the client interprets a subsequent success response as confirmation of the dropped write. All TLS 1.3 connections are affected. Both TLS clients and servers are affected. TLS 1.2 and QUIC connections are not affected. We recommend you upgrade s2n-tls to version v1.7.6
Improper Validation of Integrity Check Value
SmithyRS Recursive Deserializer Causing DoS
CVE-2026-15957
7.5 - High
- July 21, 2026
Smithy-RS is a Rust code generation and runtime framework that generates HTTP clients and servers from Smithy interface definitions, powering the AWS SDK for Rust and custom service implementations. Uncontrolled recursion in the JSON, CBOR, and XML deserializer functions emitted by Amazon smithy-rs code generation could allow remote attackers to cause a denial of service (process abort via stack exhaustion) via a small request containing deeply nested data for a recursive model shape to a generated SDK or server. To mitigate this issue, users should upgrade to aws-sdk-rust release-2026-06-02 or later. Users building custom servers with smithy-rs codegen should regenerate from smithy-rs release-2026-06-01 or later.
Allocation of Resources Without Limits or Throttling
Directory Traversal in aws-healthomics-mcp-server linting (v<0.0.36)
CVE-2026-15415
6.8 - Medium
- July 17, 2026
AWS HealthOmics is a HIPAA-eligible service that fully manages the compute, storage, and workflow engine infrastructure required to run bioinformatics analyses at scale for clinical diagnostics, drug discovery, and agricultural research. Improper limitation of a pathname to a restricted directory in the linting tools of the AWS HealthOmics MCP Server (aws-healthomics-mcp-server) before version 0.0.36 might allow an actor who can influence the MCP agent to write an actor-controlled content to arbitrary locations outside the intended workflow bundle directory, via directory traversal sequences in the workflow_files input. To remediate this issue, users should upgrade to version 0.0.36 or later.
Relative Path Traversal
AWS Athena Federation Synapse SQL Injection (Prev2026.21.1)
CVE-2026-12283
6.8 - Medium
- July 17, 2026
Amazon Athena is a serverless, interactive query service that lets you analyze data directly in Amazon S3 using standard SQL. Athena Query Federation is a feature that allows you to connect to data sources outside of Amazon S3 like DynamoDB, Azure Synapse, and custom connectors using standard SQL syntax. Improper neutralization of special elements used in an SQL command in the Synapse connector in Amazon aws-athena-query-federation v2022.20.1 through v2026.19.1 might allow an authenticated remote user to execute injected read-only SQL queries that return unintended data from the connected database via a crafted table name. To remediate this issue, users should upgrade to version v2026.21.1 or later.
SQL Injection
AWS Bedrock AgentCore SDK 1.4.8/1.5.0 Logleaks via OT Span Attrs
CVE-2026-15737
5.7 - Medium
- July 16, 2026
AWS Bedrock AgentCore Python SDK is an open-source Python library that provides client tools for building AI agents on the Amazon Bedrock AgentCore platform. Unintended logging of sensitive user content in the OpenTelemetry instrumentation in AWS Bedrock AgentCore Python SDK versions 1.4.8 and 1.5.0 might allow a local authenticated user with access to CloudWatch Logs to access raw user prompts and agent responses containing sensitive data via span attributes. The SDK wrote raw user prompts and complete agent responses into OpenTelemetry span attributes on every invocation without filtering or masking. These spans flow into the customer's aws/spans CloudWatch log group, exposing sensitive content to any principal with log read access. We recommend you upgrade to version 1.5.1 or later. Users who ran affected versions should also review and purge sensitive content from their aws/spans CloudWatch log groups.
Insertion of Sensitive Information into Log File
OS Command Injection in AWS jsii-diff (v<1.131.0) npm loading component
CVE-2026-15895
7.8 - High
- July 15, 2026

To mitigate this issue, users should upgrade to jsii-diff v1.131.0 or later.
Shell injection
SSRF in Strands Agents Tools elasticsearch_memory (pre 0.7.0)
CVE-2026-15746
6.5 - Medium
- July 15, 2026
Strands Agents is an open-source Python SDK for building and running AI agents. The strands-agents-tools package provides pre-built tools for use with the SDK, including the elasticsearch_memory tool for agent memory storage. We identified CVE-2026-15746, a server-side request forgery (SSRF) issue in the elasticsearch_memory tool. The tool exposed its connection parameters (es_url, cloud_id, api_key) as fields the large language model (LLM) could control through the tool schema. When a caller omitted the api_key parameter, the tool fell back to the operator's ELASTICSEARCH_API_KEY environment variable and sent it to whichever host the LLM specified. A crafted prompt could cause the tool to connect to a threat-actor-controlled server and disclose the operator's Elasticsearch API key in the Authorization header. We recommend you upgrade to strands-agents-tools version 0.7.0 or later. As a precautionary measure, we recommend all operators rotate their ELASTICSEARCH_API_KEY, even if there is no indication the credential was exposed.
SSRF
AWS LBC <3.4.2: Auth Remoteuser Can Spoof gRPC via HTTPRoute
CVE-2026-15738
8.5 - High
- July 14, 2026

To mitigate this issue, users should upgrade to version 3.4.2.
Separation of Privilege
AWS HealthLake MCP Server SSRF: Pagination Handling before v0.0.14
CVE-2026-15643
7.3 - High
- July 14, 2026
AWS HealthLake MCP Server (awslabs.healthlake-mcp-server) is a Model Context Protocol server that enables AI assistants to interact with AWS HealthLake FHIR datastores. A server-side request forgery in the pagination handling component in AWS awslabs.healthlake-mcp-server before 0.0.14 on all platforms might allow a remote authenticated user to exfiltrate AWS temporary security credentials to an arbitrary endpoint via a crafted next_token parameter. The server does not validate that pagination URLs point back to the expected HealthLake endpoint, allowing an actor to redirect subsequent requests to an actor-controlled server. Its recommended to upgrade to version 0.0.14 or later.
SSRF
Auth.GetUserPrivateKey API CWE-59 in AWS RES <2026.06: Improper Link Res
CVE-2026-14904
6.5 - Medium
- July 07, 2026
AWS Research and Engineering Studio (RES) is an open-source solution that enables researchers and engineers to create and manage secure virtual desktops and computing resources on AWS. Improper link resolution before file access issue (CWE-59) in the Auth.GetUserPrivateKey API. An authenticated remote user could read arbitrary files on the cluster-manager EC2 instance by replacing their SSH private key file (~/.ssh/id_rsa) with a symbolic link targeting any file on the host. Because the cluster-manager process runs as root, any file readable by root is exposed, including other users' SSH private keys and application configuration secrets. It's recommended to upgrade to RES version 2026.06.
insecure temporary file
Amazon mcp-gateway-registry <1.0.13 SQLi via retention policy
CVE-2026-14471
8.1 - High
- July 06, 2026
Improper Neutralization of Special Elements in the metrics-service retention policy management component in Amazon mcp-gateway-registry before 1.0.13 might allow an authenticated remote user to execute arbitrary SQL queries via a crafted table_name value that is interpolated into SQL statements in identifier position. To remediate this issue, users should upgrade to version 1.0.13 or later.
SQL Injection
AWS Advanced JDBC Wrapper 3.3-4.0 RemoteQueryCachePlugin Deserialization RCE
CVE-2026-14265
7.5 - High
- July 01, 2026
Deserialization of untrusted data in the RemoteQueryCachePlugin in Amazon Web Services AWS Advanced JDBC Wrapper 3.3.0 through 4.0.0 might allow an actor with write access to the shared cache infrastructure to execute arbitrary code on application servers that read cached query results via a crafted serialized Java object. The RemoteQueryCachePlugin uses ObjectInputStream without class filtering when deserializing cached query results from Redis or Valkey, enabling gadget chain execution when cache entries are poisoned. We recommend upgrading to AWS Advanced JDBC Wrapper version 4.0.1 or later.
Marshaling, Unmarshaling
OS Command Injection in aws-cdk-lib NodejsFunction Docker Bundling (v2.260.0 Fix)
CVE-2026-13760
7.3 - High
- July 01, 2026
OS command injection in the NodejsFunction Docker bundling pipeline (OsCommand helper) in AWS aws-cdk-lib on all platforms might allow a actor who controls dependency version strings in a project's package.json file to execute arbitrary commands on the host running the CDK toolchain via injected shell metacharacters in the OsCommand helper. This issue requires the actor to control the content of a package.json dependency version string that is processed during Docker-based bundling with nodeModules specified. To remediate this issue, users should upgrade to v2.260.0.
Shell injection
AWS CLI <=1.44.77 / <=2.34.28: Overly Permissive File Permissions Expose Credentials
CVE-2026-13769
5.5 - Medium
- July 01, 2026
Overly permissive file permissions in AWS CLI before 1.44.78 (v1) and 2.34.29 (v2) on Unix-like systems where the umask has not been configured to restrict file permissions (the default on most systems) may allow other local users on the same host to read credentials written by certain CLI subcommands (aws codeartifact login, aws iam create-virtual-mfa-device, aws deploy register). To remediate this issue, users should upgrade to AWS CLI 1.44.78 (v1) or 2.34.29 (v2) or later.
Incorrect Permission Assignment for Critical Resource
containerd CRI pathtraversal bug pre2.3.2/2.2.5/2.1.9
CVE-2026-53489
- July 01, 2026
containerd is an open-source container runtime. Versions prior to 2.3.2, 2.2.5 and 2.1.9 contain a bug where the CRI plugin restores container.log from a checkpoint image without validating a symlinked path. This could result in reading an arbitrary file on the host via kubectl logs. This issue has been fixed in versions 2.3.2, 2.2.5 and 2.1.9.
Symlink following
containerd CDI Annotation Injection via Untrusted Checkpoints (pre-2.3.2)
CVE-2026-53492
- July 01, 2026
containerd is an open-source container runtime. In Versions prior to 2.3.2, 2.2.5 and 2.1.9, the CRI implementation improperly trusts Container Device Interface (CDI) annotations found within untrusted checkpoint image metadata during container restoration. When restoring a container from a checkpoint, containerd preserves CDI-related annotations from the checkpoint archive rather than relying solely on the pod's create-time specification. This allows a user with pod creation permissions to bypass standard Kubernetes resource allocation and device plugin enforcement, injecting arbitrary CDI edits (such as device nodes and host mounts) into the restored container. Successful exploitation requires that the node has CDI enabled and contains a matching host CDI specification for the requested device; environments where CDI is disabled or lacking sensitive device specifications are not affected. This issue has been fixed in versions 2.3.2, 2.2.5 and 2.1.9.
Improper Input Validation
containerd CRI Checkpoint Image Cache Poisoning (v<2.3.2,2.2.5,2.1.9)
CVE-2026-50195
- July 01, 2026
containerd is an open-source container runtime. Versions prior to 2.3.2, 2.2.5 and 2.1.9 contain a vulnerability in the CRI checkpoint import process where it fails to validate the image references specified within a checkpoint image's configuration. An attacker with permissions to create pods can use a crafted checkpoint image to force containerd to pull a malicious image and assign it an arbitrary local tag, thereby poisoning the node's local image cache. Subsequently, if other pods on the same node attempt to use the poisoned tag with an IfNotPresent (or Never) pull policy, they will unknowingly execute the attacker's malicious image instead of the legitimate one. This can lead to a compromise of the affected pods, allowing the attacker to execute arbitrary code under the victim pod's identity. This issue has been fixed in versions 2.3.2, 2.2.5 and 2.1.9.
Insufficient Verification of Data Authenticity
containerd DoS via faulty image load causing OOM kill (v<1.7.33,2.0.10,2.1.9)
CVE-2026-47262
- July 01, 2026
containerd is an open-source container runtime. Versions prior to 1.7.33, 2.0.10, 2.1.9, 2.2.5 and 2.3.2, contain a vulnerability that allows a maliciously crafted image to cause a Denial of Service (DoS) condition. When creating a container from this image, memory exhaustion occurs, leading to an Out Of Memory (OOM) kill of the containerd process. This renders the container runtime API unavailable and can disrupt clients such as the Docker Engine or Kubernetes control-plane components. This issue has been fixed in versions 1.7.33, 2.0.10, 2.1.9, 2.2.5 and 2.3.2.
Resource Exhaustion
CRI Label Injection in containerd 1.7.x/2.0-2.3 (1.7.33/2.3.2)
CVE-2026-53488
- July 01, 2026
containerd is an open-source container runtime. In versions prior to 1.7.33, 2.3.2, 2.2.5, 2.1.9, and 2.0.10 the CRI plugin propagates labels from an image config (LABEL instruction in Dockerfile) to a container without validation. This may result in executing an arbitrary command on the host, via a plugin that consumes container labels for some operations. This issue has been fixed in versions 1.7.33, 2.3.2, 2.2.5, 2.1.9, and 2.0.10.
Improper Input Validation
AWS ALB HTTP/2 WAF Bypass via Fragmented Body Inspection
CVE-2026-13763
9.8 - Critical
- June 29, 2026
Inconsistent interpretation of HTTP/2 requests in AWS Application Load Balancer with AWS WAF enabled might allow remote actors to bypass AWS WAF managed rule body inspection via crafted HTTP/2 requests that fragment the request body across frames so that only a partial body is inspected. This issue only impacts HTTP/2 ALB target groups. To remediate this issue, customers should enable the "Inspect after sufficient data" target group configuration associated to an ALB load balancer. Refer to: ( https://docs.aws.amazon.com/elasticloadbalancing/latest/application/edit-target-group-attributes.html#waf-http2-inspection )
