Emerging Threat: Apache Tomcat Vulnerability CVE-2025-55752
CVE-2025-55752 is a path traversal vulnerability in Apache Tomcat. It comes from a regression introduced during a past bug fix. Because of this flaw, Tomcat normalizes URLs before decoding them, which lets attackers craft requests that bypass access controls and reach restricted directories like /WEB-INF/ and /META-INF/. In deployments where HTTP PUT is enabled, an attacker could upload files through this path and potentially gain remote code execution (RCE).
