CVE-2026-5114 Details
Description
The SpeedyCache plugin for WordPress is vulnerable to Arbitrary File Read via Path Traversal in all versions up to, and including, 1.3.8. This is due to a mismatch between CSS URL validation (which allows query strings like `.css?...`) and path resolution (which strips query strings), combined with no validation that the resolved file is actually a CSS file. This makes it possible for authenticated attackers, with Administrator-level access and above, to read arbitrary files from the server (including `wp-config.php` and `/etc/passwd`) by injecting crafted `<link>` tags into page content, with the file contents written to publicly accessible cache files.
A path traversal vulnerability allowing arbitrary file read has been identified in the SpeedyCache plugin for WordPress, affecting all versions through 1.3.8. The issue arises from a discrepancy between CSS URL validation, which permits query strings, and path resolution, which removes them, coupled with a lack of validation to ensure the resolved file is a legitimate CSS file. This vulnerability enables authenticated attackers with Administrator-level access to read arbitrary files from the server, such as wp-config.php and /etc/passwd. Exploitation involves injecting crafted <link> tags into page content, with the file contents being written to publicly accessible cache files.
Users are advised to update the SpeedyCache plugin to version 1.3.9 or a newer patched version.
