What is CVE-2026-5114?
CVE-2026-5114 is a medium-severity path traversal vulnerability in softaculous SpeedyCache – Cache, Optimization, Performance, published on 28 Jul 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official 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.
Weakness: CWE-22
