This flaw allows a user with full access to their namespace to extract the ServiceAccount token and use it to submit TokenReview and SubjectAccessReview requests, potentially revealing information about other users' permissions. While this does not allow privilege escalation or impersonation, it exposes information that could aid in gathering information for further attacks.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **RHSA-2025:3607** · Red Hat · fixed in: Red Hat OpenShift distributed tracing 3.5.3 · released 2025-04-04 · [advisory](https://access.redhat.com/errata/RHSA-2025:3607)\n- **RHSA-2025:3740** · Red Hat · fixed in: Red Hat OpenShift distributed tracing 3.5.3 · released 2025-04-09 · [advisory](https://access.redhat.com/errata/RHSA-2025:3740)\n- **Red Hat VEX** · Moderate · affected: Red Hat OpenShift distributed tracing 3 · no fix planned: Red Hat OpenShift distributed tracing 3 · updated 2026-09-08 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2025/cve-2025-2786.json)","depth":"sunlit","depthScore":24,"depthScoreParts":{"impact":23.7,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
