**Name of the Vulnerable Software and Affected Versions** Stirling-PDF versions 2.1.5 through 2.5.1 **Description** Stirling-PDF is a locally hosted web application for PDF file operations. An authenticated user can trigger a Denial of Service (DoS) condition by submitting extreme values for the `fontSize` and `widthSpacer` parameters to the `/api/v1/security/add-watermark` endpoint. This can lead to resource exhaustion and server crashes. **Recommendations** Versions prior to 2.5.2 should be updated to version 2.5.2 or later.
