CVE-2025-22599Public exploitNetwork attack vector

Browser script execution via unsanitized msg_c reflection

Published Jan 10, 2025 · Updated Jan 10, 2025

Reflected XSS in WeGIA before 3.2.8 allows remote attackers to execute script in a user's browser through a crafted msg_c value. The home.php endpoint returns msg_c in its HTML response without validation or output sanitization, causing browser-interpreted markup to be reflected unchanged. Exploitation requires a user to open an attacker-crafted request, after which the script runs in that user's WeGIA origin with the user's session privileges.
