CVE-2025-11379: Roselldk WebP Express

Medium severity, CVSS 5.3. EPSS: 0.3% chance of exploitation in the next 30 days.

The WebP Express plugin for WordPress is vulnerable to information exposure via config files in all versions up to, and including, 0.25.9. This is due to the plugin not properly randomizing the name of the config file to prevent direct access on NGINX. This makes it possible for unauthenticated attackers to extract configuration data.

Affected products

• Roselldk WebP Express: up to and including 0.25.9
