What is CVE-2019-15941?

An access control bypass vulnerability exists in the OpenID Connect implementation of LemonLDAP::NG versions 2.x through 2.0.5. This issue arises from the potential for an attacker to craft an OpenID Connect authorization request, circumventing established access control measures. The threat is accentuated when there is an OIDC Relay Party configured with less stringent access control rules than the target Resource Provider (RP), combined with inadequate URI filtering, allowing attackers to redirect requests in ways that may compromise security.
