CVE-2026-50149

A flaw was found in Contour. When an HTTPProxy is configured with both a fallback certificate and JWT JSON Web Token providers, Contour does not properly enforce JWT verification. This allows remote attackers to bypass security checks by sending requests without a valid token, specifically when...

GHSA-G3XR-5W5J-W4Q4 Contour has Improper JWT Verification for Non-SNI Requests on Virtual Hosts with Fallback Certificate Enabled

Impact When an HTTPProxy is configured with incompatible combination of both .spec.virtualhost.tls.enableFallbackCertificate: true and .spec.virtualhost.jwtProviders, Contour does not reject the configuration. Consequently, requests from clients that do not send TLS SNI or send an unrecognized SN...
