What is CVE-2025-49125?

The vulnerability in Apache Tomcat allows unauthorized access to certain resources when using PreResources or PostResources configured outside the root of the web application. This misconfiguration permits access through unexpected paths that do not enforce the same security constraints, leading to potential exploitation of sensitive data or resources. Users are advised to upgrade to the most recent versions to mitigate this risk.

Affected Version(s)

Apache Tomcat 11.0.0-M1 <= 11.0.7

Apache Tomcat 10.1.0-M1 <= 10.1.41
