Description

We have identified a critical security vulnerability (CVE-2025-24813) in Apache Tomcat components used by WebAPI. This issue allows Remote Code Execution (RCE), information disclosure, and potential injection of malicious content through the Default Servlet when handling file uploads.

Research direction

Start by locating the WebAPI dependency declarations for tomcat-embed-core 8.5.43 and catalina.jar 9.0.89. Verify the affected components are upgraded to patched versions and review the Default Servlet file-upload handling for the stated filename validation requirement; done means the vulnerable versions and reported upload risks are addressed.
