Interpretation Conflict, leading to Incorrect Authorization vulnerability in Apache APISIX.
With match_uri_encoded_slash enabled and skip_mtls_uri_regex
configured, a client without a certificate can reach an upstream
behind a route that requires one, limited to request paths that decode
to an exempted URI. This issue affects Apache APISIX: from 3.18.0 through 3.19.0.
Users are recommended to upgrade to version 3.20.0, which fixes the issue.
