CVE-2026-63262 4.3 - Medium - July 21, 2026

Missing Authorization (CWE-862) in Kibana can lead to unauthorized cross-space information disclosure via user-supplied input that circumvents space-level access control.

AuthZ

Kibana ML Feature Uncontrolled Resource Consumption (CWE-400) DoS
CVE-2026-63261 6.5 - Medium - July 21, 2026

Uncontrolled Resource Consumption (CWE-400) in Kibana can lead to denial of service via Excessive Allocation (CAPEC-130). A low-privileged authenticated user can send a specially crafted request to a Kibana machine learning feature, causing the server to exhaust available memory and become unavailable to all users.

Resource Exhaustion

Kibana Uncontrolled Resource Consumption via Oversized Payload DoS
CVE-2026-63260 6.5 - Medium - July 21, 2026

Uncontrolled Resource Consumption (CWE-400) in Kibana can lead to denial of service via Excessive Allocation (CAPEC-130). An authenticated attacker with low-privilege access can trigger a denial of service condition in Kibana by sending a specially crafted, oversized request payload. Processing this user-supplied input requires resource-intensive memory allocation that can exhaust the available heap memory in the Kibana process, causing it to crash and become unavailable to all users.

Resource Exhaustion

Kibana Auth Bypass via User-Key Exposes Scheduled Query Data
CVE-2026-63259 4.3 - Medium - July 21, 2026

Authorization Bypass Through User-Controlled Key (CWE-639) in Kibana can lead to information disclosure via user-supplied identifiers that reference scheduled query result data from Kibana Spaces the requester is not authorized to access.

Insecure Direct Object Reference / IDOR

Kibana ML ACL Bypass Enables Audit & Notification Record Manipulation
CVE-2026-63145 4.3 - Medium - July 21, 2026

Incorrect Authorization (CWE-863) in Kibana can lead to integrity compromise of Machine Learning audit and notification records via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). A vulnerability exists in Kibana's Machine Learning functionality where a Machine Learning management endpoint performs an insufficient authorization check. The endpoint validates only a coarse privilege level but does not verify that the requesting user has access to the specific Machine Learning job or notification resources provided in the request. As a result, a low-privileged user with Machine Learning access in any Kibana space can manipulate Machine Learning audit and notification records for arbitrary jobsincluding jobs in other spaces or belonging to other usersby leveraging Kibana's internally elevated credentials to write to restricted Machine Learning system indices that the user cannot access directly.

AuthZ

Missing Auth in Kibana Unauthorized Data Disclosure
CVE-2026-63143 4.3 - Medium - July 21, 2026

Missing Authorization (CWE-862) in Kibana can lead to unauthorized information disclosure via Privilege Abuse (CAPEC-122). A user with limited feature privileges can access workflow execution outputs in their Kibana space without the authorization required to do so through the documented API. The accessible data may include sensitive information returned by workflow steps, such as results from connected data sources that the caller would not otherwise be authorized to access.

AuthZ

Kibana Reporting: Auth Bypass via Missing Disallowed Inputs (CWE-184)
CVE-2026-63142 5 - Medium - July 21, 2026

Incomplete List of Disallowed Inputs (CWE-184) in Kibana can allow an authenticated attacker with access to the Reporting feature to bypass outbound request restrictions configured by an administrator, causing the reporting service to send requests to network destinations that should be denied by the configured security policy.

AuthZ

Kibana Auth Bypass: Authenticated Users can Modify Cloud Connect Settings
CVE-2026-63141 6.3 - Medium - July 21, 2026

Missing Authorization (CWE-862) in Kibana allows an authenticated user to access and modify Cloud Connect configuration and service settings without the required feature privileges, via direct requests to insufficiently protected product endpoints.

AuthZ

Kibana Canvas Authenticated DoS via Uncontrolled Resource Consumption
CVE-2026-63139 6.5 - Medium - July 21, 2026

Uncontrolled Resource Consumption (CWE-400) in Kibana can lead to denial of service via Excessive Allocation (CAPEC-130). An authenticated low-privileged user can exploit an uncontrolled resource consumption vulnerability in Kibana's Canvas functionality by sending a specially crafted request, causing the Kibana server process to terminate and resulting in a denial of service for all users of the affected Kibana instance.

Resource Exhaustion

Kibana Auth Bypass via UserControlled Key (CWE639)
CVE-2026-56147 7.1 - High - July 21, 2026

Authorization Bypass Through User-Controlled Key (CWE-639) in Kibana can lead to unauthorized information disclosure and case attachment integrity compromise via Privilege Abuse (CAPEC-122). An inconsistency in Kibana's file access authorization logic allows a low-privileged authenticated user to retrieve, modify, and delete case attachments that belong to feature areas they are not authorized to access. Because the access control check and the resource retrieval use different resolution mechanisms, an authenticated attacker with limited file management permissions can obtain the contents of, modify, or delete protected case attachments such as those associated with Security Solution cases without holding the privileges required to access those features.

Insecure Direct Object Reference / IDOR

Kibana Improper Access Control Enables Unauthorized Watchlist Modification
CVE-2026-56146 5.4 - Medium - July 21, 2026

Improper Access Control (CWE-284) in Kibana can lead to unauthorized modification of Entity Analytics Watchlist configuration and potential information disclosure. A low-privileged authenticated user with read-only Security Solution access could perform write operations on watchlist data that should require elevated privileges. Under specific deployment conditions, this could also allow such a user to access data beyond their authorized scope.

AuthZ

DoS via Oversized Input in Kibana Entity Analytics
CVE-2026-42397 6.5 - Medium - July 21, 2026

Allocation of Resources Without Limits or Throttling (CWE-770) in Kibana can lead to a denial of service via Excessive Allocation (CAPEC-130).

CVE-2026-49095 7.2 - High - May 28, 2026

Improper Input Validation (CWE-20) in the Kibana Fleet agent policy management feature can lead to privilege escalation. An authenticated user with Fleet management privileges can manipulate agent policy configuration by injecting values into a configuration override mechanism that is not adequately validated. An attacker can cause Elastic Agents to be issued API keys with elevated Elasticsearch privileges, potentially granting unauthorized read and write access to sensitive Elasticsearch security indices beyond what is intended for the Fleet management role.

Improper Input Validation

Kibana SSRF Auth Users Bypass Egress Allowlist via Webhook Connector
CVE-2026-42398 7.7 - High - May 28, 2026

Server-Side Request Forgery (CWE-918) in Kibana allows authenticated users with connector management privileges to bypass the operator-configured connection allowlist.
