CVE-2023-6393: Red Hat Build Of Quarkus

Medium severity, CVSS 5.3. EPSS: 0.6% chance of exploitation in the next 30 days.

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.
