Unauthorized actions via missing nonce verification
Published Oct 5, 2024 · Updated Apr 28, 2026
CSRF in Tinify TinyPNG – JPEG, PNG & WebP image compression 3.4.3 and earlier allows remote attackers to trigger unauthorized actions. The affected request handler processes a state-changing request without validating a WordPress nonce, but the vendor does not identify the handler or operation. Exploitation requires a logged-in privileged user to be induced to submit an attacker-controlled request; the exact change and service effect are undisclosed.
