CVE-2024-55199Public exploitNetwork attack vector

Stored script execution via uploaded PDF rendering

Published Mar 10, 2025 · Updated Mar 10, 2025

Stored XSS in Celk Sistemas Celk Saude 3.1.252.1 allows remote authenticated users to execute script in another user's browser. The upload feature accepts a PDF containing attacker-supplied JavaScript, and the PDF rendering path treats that script as active browser content instead of neutralizing it. Exploitation requires upload privileges and another user to render the crafted PDF, allowing the script to read or alter data exposed to that page.
