OpenBao has Reflected XSS in its OIDC authentication error message
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
Workarounds
The vulnerability can be mitigated by removing any roles with callback_mode set to direct.

OpenBao is an open source identity-based secrets management system. Prior to version 2.5.2, 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. The `error_description` parameter has been replaced with a static error message in v2.5.2. The vulnerability can be mitigated by removing any roles with `callback_mode` set to `direct`.
