Impact
OpenBao installations that have an OIDC/JWT authentication method enabled and a role with callback_mode=direct configured are vulnerable to XSS via the error_description parameter on the page for a failed authentication.
This allows an attacker access to the token used in the Web UI by a victim.
Patches
The error_description parameter has been replaced with a static error message in v2.5.2
