Published Jun 1, 2021 · Updated Aug 3, 2024

Stored XSS in Fakhri Alsadi Content Copy Protection & Prevent Image Save 1.3 and earlier allows remote attackers to inject scripts via CSRF. The settings handler accepts forged POST values for image_save_msg and no_menu_msg and stores them without validation or sanitization.
