CVE-2025-66039
Versions are vulnerable to authentication bypass when the authentication type is set to "webserver." When providing an Authorization header with an arbitrary value, a session is associated with the target user regardless of valid credentials.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.28%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
