CVE-2026-68525 is a critical incorrect authorization vulnerability in Apache Tomcat's FORM authentication process. It allows bypassing a security constraint that restricts user access to a resource's POST method but not its GET method. This affects multiple Apache Tomcat versions including 11.0.0-M1 through 11.0.24, 10.1.0-M1 through 10.1.57, and 9.0.0.M1 through 9.0.120, as well as some end-of-life versions. The issue is fixed in versions 11.0.25, 10.1.58, and 9.0.121.
