Technical details
An Insufficient Verification of Data Authenticity vulnerability (CWE-345) exists in the Apache APISIX openid-connect plugin. Under default configurations, the plugin fails to properly validate identity headers, creating an attack surface for header spoofing. A remote attacker with low privileges can exploit this to bypass authentication mechanisms and gain unauthorized access to upstream resources. The issue affects versions 2.3 through 3.16.0 and is resolved in version 3.17.0 (or 3.16.1 as per some advisory notes).
