CVE-2025-3962Public exploitNetwork attack vector

Stored script execution via unsanitized comment content

Published Apr 27, 2025 · Updated Apr 28, 2025

Stored cross-site scripting in withstars Books-Management-System 1.0 allows remote authenticated users to inject script through comments. The comment-add handler stores the content parameter without neutralizing executable markup, and an article view renders the stored value as active script. Submission requires a logged-in session, and execution requires another user to view the affected article, exposing that user's browser context to attacker-controlled code.
