CVE-2026-124723
Apache APISIX: unauthorized access to mTLS protected resources
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.
