CVE-2026-7311 Details
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.
A vulnerability allowing arbitrary file deletion has been identified in the TinyPNG – JPEG, PNG & WebP image compression plugin for WordPress, affecting all versions through 3.6.13. The issue arises from inadequate file path validation in the 'delete_converted_image_size' function. This vulnerability enables authenticated attackers with author-level access and above to delete arbitrary files on the server. Exploitation of this flaw could lead to remote code execution if a critical file, such as 'wp-config.php', is deleted. To exploit this vulnerability, an attacker must inject a file path into the 'convert.path' field of the 'tiny_compress_images' post meta for an attachment they own, and then trigger the deletion of that attachment.
Users are advised to update the TinyPNG WordPress plugin to version 3.6.14 or later.
