An authenticated attacker can craft a URL that injects script tags executing in the victim's browser session.

MEDIUM 4.8EPSS 0.24%

Does this matter?

Lower severity and a low EPSS score (0.24%). Track it; it rarely justifies an emergency change on its own.

Description

Guardian language-system fails to sanitize the id GET parameter before inserting it into multiple HTML form action attributes in text_file.php (lines 94, 101, 323, 403, 826, 852). An authenticated attacker can craft a URL that injects script tags executing in the victim's browser session.
