概要
Tomcat often reaches production through a framework parent, a BOM, an embedded servlet container, or a base image rather than a single obvious dependency line. CVE-2025-48989 is an HTTP/2 denial-of-service advisory; FixVibe treats a repo match as dependency evidence, not proof that HTTP/2 is enabled or reachable on the deployed service.
仕組み
The repo check looks for Tomcat Coyote and embedded-core Maven coordinates in Java build files. Exact declared versions produce the strongest signal; compatible manifest ranges are reported when they clearly allow an affected Tomcat release line. The finding stays scoped to dependency evidence and does not claim FixVibe sent HTTP/2 reset traffic.
被害範囲
If an affected Tomcat runtime is deployed with the vulnerable HTTP/2 path exposed, attackers may be able to drive resource exhaustion and denial of service. A repo match should trigger dependency-tree review, artifact rebuild, and runtime verification before anyone treats it as confirmed production exposure.

What FixVibe checks
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 9.0.108, 10.1.44, 11.0.10, 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.
