Description
This security bulletin contains information about 1 security vulnerability.
1) Improper access control (CVE-ID: CVE-2023-6393)
The vulnerability allows a remote user to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions 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. A remote user can send a specially crafted request to the server and obtain information that belongs to another user.
Remediation
Install update from vendor's website.
