Technical details

An incorrect authorization vulnerability (CWE-863) exists in the authz-casdoor plugin of Apache APISIX. When running under default configurations, the plugin fails to properly validate the source of authentication credentials, leading to a form of incorrect session sharing or credential cross-contamination. A remote attacker with low privileges can exploit this to authenticate themselves using credentials from a different source than intended. The vulnerability affects versions 2.14.1 through 3.16.0 and is resolved in version 3.17.0.
