Medium (5.3) in redhat build of quarkus. EPSS 0.6% chance of exploitation in the next 30 days. Fixed in io.quarkus:quarkus-cache 3.2.9.Final, 3.5.2.
A flaw was found in the Quarkus Cache Runtime. 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.
