How to fix?

Upgrade Debian:12 lemonldap-ng to version 2.0.6+ds-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream lemonldap-ng package and not the lemonldap-ng package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

OpenID Connect Issuer in LemonLDAP::NG 2.x through 2.0.5 may allow an attacker to bypass access control rules via a crafted OpenID Connect authorization request. To be vulnerable, there must exist an OIDC Relaying party within the LemonLDAP configuration with weaker access control rules than the target RP, and no filtering on redirection URIs.
