Settings change via missing nonce validation
Published Feb 20, 2024 · Updated Apr 8, 2026
Cross-site request forgery in ImageRecycle PDF & Image Compression 3.1.13 and earlier allows remote attackers to disable image optimization. The disableOptimization function accepts a state-changing request without validating a WordPress nonce, so the administrator’s authenticated session applies the setting change. Exploitation requires a signed-in administrator to open an attacker-controlled link; the documented consequence is limited to disabling optimization.
