Quarkus Cache Runtime @CacheResult Context Leakage via Cached Uni
CVE-2023-6393 Published on December 6, 2023
Quarkus: potential invalid reuse of context when @cacheresult on a uni is used
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.
