CVE-2026-43512 May 12, 15:24 Maven CRITICAL PATCH GHSA Act Now

Authentication bypass in Apache Tomcat's DIGEST authentication implementation allows remote attackers to circumvent HTTP Digest access authentication and reach protected resources without valid credentials, affecting Tomcat 7.0.0-7.0.109, 8.5.0-8.5.100, 9.0.0.M1-9.0.117, 10.1.0-M1-10.1.54 and 11.0.0-M1-11.0.21. The NVD-published CVSS of 9.8 reflects an unauthenticated network vector with total impact, but this record is marked DEPRECATED by the CVE program and there is no public exploit identified at time of analysis, with EPSS at just 0.04% (12th percentile) and no CISA KEV listing. Impact is scoped to deployments that actually enable DIGEST authentication, which is uncommon relative to Tomcat's overall footprint.
