CVE-2023-44469Network attack vector

Authenticated SSRF via unrestricted OIDC request URI

Published Sep 29, 2023 · Updated Sep 23, 2024

Server-side request forgery in LemonLDAP::NG before 2.17.1 allows remote authenticated users to send GET requests to arbitrary URLs. The OpenID Connect issuer passes request_uri to getRequestJWT without first checking the URI against a relying-party allowlist. Authentication is required, and the documented effect is an attacker-selected server-side GET rather than direct response-body disclosure.
