概要
Tomcat clustering can reach production through direct Tomcat modules, embedded servlet containers, framework-managed dependencies, or base images. CVE-2026-34486 is tied to exact patch releases where EncryptInterceptor protection can be bypassed under clustering conditions, so FixVibe keeps dependency evidence separate from confirmed runtime exposure.
仕組み
The repo check looks for Tomcat, Tomcat Tribes, Catalina, or embedded-core Maven coordinates in Java build files. It reports only exact affected versions in the 9.0.x, 10.1.x, and 11.0.x release lines, including versions referenced through local Maven properties. The finding stays scoped to dependency evidence and does not claim FixVibe inspected live cluster traffic.
被害範囲
If an affected Tomcat runtime is deployed with the relevant clustering configuration and network boundary, sensitive inter-node traffic that operators expect to be encrypted may not receive the intended protection. A repo match should drive Tomcat version alignment, artifact rebuilds, and cluster configuration review before anyone treats it as confirmed plaintext exposure.

FixVibe repo scans look for high-confidence security patterns and dependency risk in source context. Reports identify the affected area and recommended fix.

鉄壁の防御
Upgrade the active Tomcat release line to 9.0.117, 10.1.54, 11.0.21, or newer. Update direct Tomcat artifacts, BOMs, Spring Boot-managed versions, Gradle constraints, or container base images as needed, then rebuild and redeploy the actual WAR, JAR, or image. Review cluster configuration so EncryptInterceptor remains intentionally configured after rollout.
