When request processing utilizes a Uni cached using @CacheResult and the cached Uni reuses the initial \"completion\" context, the processing switches to the cached Uni instead of the request context. This is a problem if the cached Uni context contains sensitive information, and could allow a malicious user to benefit from a POST request returning the response that is meant for another user, gaining access to sensitive data.\n\n## Affected\n\n- `build_of_quarkus`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":29,"depthScoreParts":{"impact":29.2,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
