Summary
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.
Red Hat rates this as a Moderate impact due to the difficulty and randomness that is required to successfully exploit this vulnerability. Red Hat severity: Moderate — CVSS 5.3 (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N).
Weakness: CWE-200. Affected Red Hat products: Red Hat build of Quarkus.
Red Hat does not currently list a fixing RHSA for this CVE.
