Denial of Service Vulnerability in Red Hat Connectivity Link's Authorization Service

CVE-2025-25207

What is CVE-2025-25207?

The Authorino service within Red Hat Connectivity Link, designed for zero trust API security, exposes a flaw that can be exploited by attackers with developer persona access. This vulnerability allows them to add excessive callbacks to HTTP endpoints post-authorization. As the service enforces authentication policies through a single instance, an attacker can effectively trigger a Denial of Service condition, impeding legitimate authorization processes and potentially disrupting services reliant on Authorino.
