What is CVE-2026-7311?
CVE-2026-7311 is a high-severity path traversal vulnerability in TinyPNG – JPEG, PNG & WebP image compression, published on 2 Jul 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
The TinyPNG – JPEG, PNG & WebP image compression plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the delete_converted_image_size function in all versions up to, and including, 3.6.13. This makes it possible for authenticated attackers, with author-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). An attacker can exploit this by injecting an arbitrary server file path into the 'convert.path' field of the 'tiny_compress_images' post meta on an attachment they own, then triggering attachment deletion to invoke the vulnerable code path.
