CVSS 3.799999952316284 LOW
Record from redhat · Published September 14, 2026
A vulnerability was found in Apache Tomcat. When processing an HTTP/2 stream, Tomcat did not handle some cases of excessive HTTP headers correctly. This issue led to a miscounting of active HTTP/2 streams, which in turn led to using an incorrect infinite timeout that allowed connections to remain open that should have been closed.
