CVE-2026-7311— TinyPNG 路径遍历漏洞

TinyPNG <= 3.6.13 - Authenticated (Author+) Arbitrary File Deletion via 'convert.path' in 'tiny_compress_images' Post Meta

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.

CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H

对路径名的限制不恰当(路径遍历)

TinyPNG 路径遍历漏洞

TinyPNG TinyPNG是TinyPNG公司的一款WordPress图像压缩与优化插件。 TinyPNG 3.6.13及之前版本存在路径遍历漏洞，该漏洞源于delete_converted_image_size函数中对文件路径验证不足，可能导致经过身份验证的攻击者（作者级别及以上）删除服务器上的任意文件，进而导致远程代码执行。
