CVE-2026-41284 is an allocation-of-resources-without-limits-or-throttling flaw in Apache Tomcat WebDAV LOCK and PROPFIND request handling. Tomcat did not enforce a request-body limit for these methods, resulting in an unbounded read and uncontrolled resource allocation. Affected supported releases include Tomcat 11.0.0-M1 through 11.0.21, 10.1.0-M1 through 10.1.54, and 9.0.0.M1 through 9.0.117; older unsupported releases may also be affected.
