1) Exposure of Data Element to Wrong Session (CVE-ID: CVE-2026-82806)

CWE-ID: CWE-488 - Exposure of Data Element to Wrong Session

CVSSv4: 5.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to obtain unintended authorization.

The vulnerability exists due to improper session data isolation in authz-keycloak authorization scope handling when processing requests on the same route. A remote user can send requests on the same route to cause authorization scopes to persist into later requests and obtain unintended authorization.

The issue occurs under a supported authz-keycloak configuration.
