Recent Red Hat Security Vulnerabilities
| CVE | Date | Vulnerability | Products |
|---|---|---|---|
| CVE-2026-83535 | Oct 12, 2026 |
OpenStack Network Exporter Basic Auth Bypass via TLS MisconfigA flaw was found in openstack-network-exporter. When an operator configures user authentication but omits or misconfigures Transport Layer Security (TLS), the basic authentication mechanism is silently bypassed. This fail-open design allows an adjacent network attacker to access sensitive Open vSwitch (OVS) and Open Virtual Network (OVN) dataplane metrics without credentials. Consequently, an attacker can enumerate bridge names, port counters, OVN controller state, and host topology, leading to information disclosure. |
|
| CVE-2026-83536 | Oct 12, 2026 |
openstack-network-exporter DoS via missing ReadHeaderTimeoutA flaw was found in openstack-network-exporter. The HTTP server within the component is configured without essential timeout settings, such as ReadHeaderTimeout. This vulnerability allows an unauthenticated, remote attacker to initiate multiple slow HTTP header connections. By trickling header bytes, the attacker can exhaust server resources, specifically file descriptors, leading to a Denial of Service (DoS) that prevents legitimate Prometheus metric scraping and alerting. |
|
| CVE-2026-85471 | Oct 12, 2026 |
Quay SSRF: Hostname blacklist bypass in webhook notificationsA flaw was found in Quay. An authenticated repository administrator could bypass the hostname blacklist in webhook notifications, leading to a Server-Side Request Forgery (SSRF) vulnerability. This allows the Quay application to be tricked into sending requests to internal network resources, such as cloud metadata services or other services within the cluster. Consequently, this could lead to the disclosure of sensitive information from these internal services. |
|
| CVE-2026-87744 | Oct 12, 2026 |
Quarkus REST Panache unauth access via @MethodPropsA flaw was found in Quarkus REST Data Panache. This vulnerability allows unauthenticated attackers to bypass security controls on generated endpoints. When a developer customizes a specific operation using @MethodProperties without explicitly re-declaring security roles, the code generator silently drops class-level security requirements. This results in the affected endpoint defaulting to permissive, unauthenticated access, potentially leading to unauthorized information disclosure or data modification. |
|
| CVE-2026-75888 | Oct 12, 2026 |
OpenShift Console SSRF via Helm Chart URL (CVE-2026-75888)A flaw was found in the OpenShift console. An authenticated console user can exploit a Server-Side Request Forgery (SSRF) vulnerability by providing a specially crafted Helm chart URL without proper validation. This allows the user to make the console pod fetch arbitrary URLs, potentially leading to the disclosure of sensitive information through error messages or enabling blind port scanning within the cluster. |
|
| CVE-2026-94451 | Oct 12, 2026 |
Quarkus REST Data Panache Sort Param Bypass Allows Data Leak & DoSQuarkus REST Data Panache provides a way to automatically generate REST endpoints for data entities. A flaw was found where certain endpoints do not properly check the sort parameter provided by users. This could allow an attacker to learn information they should not have access to or slow down the system by forcing the database to perform complex tasks, potentially causing a denial of service. |
|
| CVE-2026-52903 | Oct 12, 2026 |
Deserialization RCE via YAML.safe_load override in ManageIQA deserialization of untrusted data vulnerability was found in ManageIQ. The YamlLoadAliases module overrides YAML.safe_load to silently fall back to YAML.unsafe_load in production when a Psych::DisallowedClass error occurs. An authenticated attacker with dialog import access can exploit this to achieve remote code execution by uploading a crafted YAML payload that triggers the fallback and deserializes arbitrary Ruby objects. Red Hat CloudForms, which was based on ManageIQ, has reached End of Life and is no longer supported. No errata or patches will be issued. This CVE is being assigned for the benefit of the ManageIQ community and downstream consumers. |
|
| CVE-2026-94447 | Oct 08, 2026 |
Go cmd/go Checksum Bypass (Go <1.26.9, 1.27.0-1.27.2)Previously, a user operating inside of a malicious Go project that defines a bogus golang.org/toolchain go.sum entry and operates a malicious GOMODPROXY the user chooses to use can bypass the intended checksum. We now ensure that golang.org/toolchain always goes to the network for the canonical checksum. |
|
| CVE-2026-94444 | Oct 08, 2026 |
Go cmd/go Module Injection via bogus golang.org/fips140 (<=1.27.1)Previously, a user operating inside of a malicious Go project that defines a bogus golang.org/fips140 and operates a malicious GOMODPROXY the user chooses to connect to can serve an arbitrary module in its place. We now unpack the trusted ziphash for the bundled golang.org/fips140 module and construct its entry in the GOMODCACHE such that it can be verified by the toolchain. |
|
| CVE-2026-89091 | Oct 08, 2026 |
Ansible Core Tarball Path Traversal via Symlink Chain ExploitA flaw was found in ansible-core. When installing a collection with `ansible-galaxy collection install`, the archive extractor validates member paths using lexical path normalisation (os.path.abspath) instead of resolving symbolic links (os.path.realpath), and it performs no containment check on symlink-typed directory members before creating them. A crafted collection tarball can chain symlink directory entries so that a subsequent file member is written outside the intended destination directory. This allows an attacker who can get a victim to install a malicious collection to overwrite arbitrary files with the privileges of the user running ansible-galaxy, leading to code execution on the control node. This is a bypass of the fix for CVE-2020-10691. |

| CVE-2026-93017 | Oct 08, 2026 |
OpenShift Insights Operator: Misconfigured ClusterRole Grants All SecretsThe `insights-operator-gather` ClusterRole grants the operator's service account read access to secrets in the core API group with no namespace or resourceNames restriction therefore, access to every secret in every namespace in the cluster. Ref: https://github.com/openshift/insights-operator/blob/8f15e3157ff09f54ab22801f5b21da35a195cc6d/manifests/03-clusterrole.yaml#L368-L373 ``` - apiGroups: - "" resources: - secrets verbs: - get - list ``` By spawning a pod with the gather service account mounted, an attacker will be able to access any secret in any namespace. ``` spec: serviceAccountName:"gather" ``` |
|
| CVE-2026-56851 | Oct 07, 2026 |
Nickname Profile Out-of-Bounds Panic in GoThe Nickname profile can panic with an out-of-bounds slice error when transforming crafted input into a short destination buffer. |
|
| CVE-2026-77214 | Oct 07, 2026 |
Heap Buffer Over-Read in libexpat XML_ParseBuffer (CVE-2026-77214)libexpat before commit 13c5f63 contains a heap buffer over-read vulnerability in xmlparse.c. XML_ParseBuffer advances the parse buffer end with parser->m_bufferEnd += len using a caller-supplied length that is not validated against the allocated buffer size, so repeated XML_ParseBuffer calls move m_bufferEnd past the end of the heap allocation and subsequent parsing reads out of bounds. Reaching this path requires a parse buffer to already be present; otherwise XML_ParseBuffer returns XML_ERROR_NO_BUFFER. A buffer is present after a prior call to XML_GetBuffer, either directly (the common case) or indirectly through a prior XML_Parse call that allocates the buffer internally. The over-read discloses adjacent heap memory to the calling application, recovering heap pointers, libc function pointers, and code pointers sufficient to defeat ASLR and build further exploitation primitives. |
|
| CVE-2026-80048 | Oct 06, 2026 |
Red Hat sssd-kcm Local DoS via Large Request HeaderA flaw was found in `sssd-kcm`. A local user or process able to connect to the `sssd-kcm` UNIX socket can exploit this vulnerability. By sending a large request length header and then stalling the connection, an attacker can cause the system to preallocate significant memory. This leads to memory exhaustion within the `sssd-kcm` responder, resulting in a Denial of Service (DoS) for affected deployments. |
|
| CVE-2026-76061 | Oct 06, 2026 |
CRI-O bind_mount_prefix Symlink Spoof leads to Host Path EscalationA flaw was found in CRI-O's `bind_mount_prefix` handling. When configured with a non-empty `bind_mount_prefix`, a malicious container or local attacker could use a Container Runtime Interface (CRI) hostPath containing an intermediate absolute symlink. This could cause the bind mount source to resolve outside the intended prefixed root, potentially leading to unauthorized access to files or privilege escalation on the host system. |
|
| CVE-2026-83550 | Oct 06, 2026 |
Go Postgres-Exporter: pprof debug endpoints exposed, info disclosure & DoSA flaw was found in postgres-exporter. Due to the blank import of `net/http/pprof`, debug endpoints are exposed on the unauthenticated metrics listener. A remote attacker within the cluster network can access these endpoints. This allows for information disclosure, potentially revealing process arguments, full goroutine stacks, and sensitive data like database connection strings or passwords from heap dumps. Additionally, repeated CPU profiling through these endpoints can lead to a denial of service. |
|
| CVE-2026-88252 | Oct 06, 2026 |
SSSD Local DoS via Responder Service File Descriptor ExhaustionA flaw was found in sssd. A local user can cause a Denial of Service (DoS) by exhausting the responder service's available file descriptors (system handles used for open connections). By opening and maintaining many concurrent connections to a responder socket while continuing to queue new connection attempts, an attacker can trigger an unthrottled retry loop. This condition leads to high CPU utilization and stalls the service, preventing legitimate identity and authentication requests from being processed. |
|
| CVE-2026-92821 | Oct 06, 2026 |
SSSD LDAP Expired-Password Bypass via Early Rule TerminationA flaw was found in SSSD. When configured to evaluate password expiration warnings before restrictive access rules in LDAP (Lightweight Directory Access Protocol) environments, an expired-password warning terminates rule evaluation early and treats the access request as successful. A remote authenticated user with an expired password using an alternative authentication method, such as SSH public key authentication, can exploit this flaw to bypass access control restrictions and gain unauthorized access to protected systems. |
|
| CVE-2026-71297 | Oct 05, 2026 |
Red Hat Maestro gRPC Broker Auth Bypass via Client CertA flaw was found in the maestro gRPC broker. This vulnerability allows a remote attacker, with a valid client certificate, to bypass authentication. This bypass enables the attacker to subscribe to other consumers' event streams, leading to unauthorized information disclosure, or to publish forged agent status, which can compromise data integrity. |
|
| CVE-2026-71299 | Oct 05, 2026 |
Maestro REST API Auth Bypass: UnAuth Writes PossibleA flaw was found in Maestro. Its REST API write endpoints were registered without proper authentication middleware. This allows a remote attacker to perform unauthorized write operations, such as creating, modifying, or deleting consumers and resource bundles. This could lead to data integrity issues or a denial of service (DoS). |
|
| CVE-2026-71298 | Oct 05, 2026 |
Unauthenticated SQLi in RedHat Maestro REST orderBy for Data ExfiltrationA flaw was found in maestro. A remote attacker could exploit a SQL injection vulnerability in the `orderBy` query parameter of its REST API list endpoints. This flaw, which does not require authentication, allows for read-only blind extraction of data from the database. |
|
| CVE-2026-94422 | Oct 02, 2026 |
xdg-dbus-proxy <0.1.9 Bypass DBus Message Filtering, Code ExecAn incorrect implementation of message filtering in xdg-dbus-proxy versions before 0.1.9 allows an attacker to bypass the intended message filtering on the D-Bus session bus by setting a reply serial number on non-reply messages. A malicious or compromised Flatpak app could use this to achieve arbitrary code execution outside its sandbox. xdg-dbus-proxy was designed to be part of the sandbox boundary for Flatpak, but it is released as a separate project and is sometimes used by other app frameworks such as Firejail. |
|
| CVE-2026-83663 | Oct 02, 2026 |
Apache Thrift Go Bindings Uncontrolled Recursion (pre-0.25.0)Uncontrolled Recursion vulnerability in Apache Thrift go bindings. Both Go transports satisfy a read out of a buffered frame and, when that frame yields no payload bytes, read the next frame and call `Read` again instead of looping. A peer produces such a frame for 4 bytes in `TFramedTransport` (a declared size of zero) or 18 bytes in `THeaderTransport` (a header block that fills the frame), so nothing bounds the depth. The Go stack limit is reached as a `fatal error`, which `recover()` cannot catch, so the whole process dies. This issue affects Apache Thrift: before 0.25.0. Users are recommended to upgrade to version 0.25.0, which fixes the issue. |
|
| CVE-2026-94637 | Oct 02, 2026 |

|
| CVE-2026-95512 | Oct 02, 2026 |
FreeType CID Font Loader Memory DoS via Repeated AllocationsA flaw was found in FreeType, specifically within its CID font loader. A remote attacker could exploit this vulnerability by tricking a user into opening content that embeds or references a specially crafted CID-keyed font. This crafted font can cause repeated allocations and decryptions of subroutine data across multiple font dictionaries, leading to excessive memory and CPU consumption. This can result in a denial of service (DoS) for the application or service processing the font, potentially causing it to hang or terminate. |
And others... |
| CVE-2026-86345 | Oct 01, 2026 |
389-ds-base LDAP StartTLS buffer injection allows auth bypassA flaw was found in 389-ds-base. The server does not discard plaintext bytes already buffered from a client connection when negotiating StartTLS, allowing an on-path attacker to inject a crafted LDAP message that is processed after the TLS upgrade and whose response is delivered to the client in place of the client's own pending operation's response, due to messageID collision. This can cause a client application to treat a failed authentication (bind) attempt as successful. |
|
| CVE-2026-86344 | Oct 01, 2026 |
389-ds LDAP Thread Exhaustion DoS via Incomplete LDAPMessageA flaw was found in 389-ds-base. An unauthenticated remote attacker can send a complete LDAP operation followed by the first bytes of an incomplete LDAPMessage on the same connection, causing the server to hand that connection to a second worker thread before the first worker's result is flushed. The second worker blocks until nsslapd-ioblocktimeout while holding the connection mutex, preventing delivery of the completed operation's result. Repeating this across a small number of connections proportional to the configured worker-thread pool size exhausts the entire pool under default configuration, denying service to all clients (anonymous and authenticated, plaintext and TLS) for as long as the attacker maintains the connections. |
|
| CVE-2026-56098 | Oct 01, 2026 |
Katello RegistryProxiesController Auth Bypass Enables User EnumerationA flaw was found in rubygem-katello. The RegistryProxiesController in Katello contains an authorization bypass vulnerability due to an execution fall-through in the registry_authorize filter. While the application identifies unauthorized requests and triggers an error response via the unauthorized method, it fails to halt the execution of the current code path (missing return statement). This failure in the control flow allows the application to proceed into subsequent business logic and database validation filters. Consequently, the application reveals its internal state through differential responses, allowing an unprivileged attacker to enumerate valid Users, Organizations, and Products across the entire instance. |
