CVE Catalog

CVE-2026-6403

High
Published: Translated: NVD NIST

Summary

The Quick Playground plugin for WordPress is vulnerable to Path Traversal in versions up to and including 1.3.3. This is due to insufficient path validation in the qckply_zip_theme() function, allowing a user-controlled 'stylesheet' parameter to be appended directly to the theme root directory path without sanitizing directory traversal sequences.

Risk Assessment

Unauthenticated attackers can trigger the creation of a ZIP archive containing arbitrary files from the server's filesystem, including wp-config, posing a serious risk to data security.

Recommendation

It is recommended to update the plugin to the latest version to mitigate this vulnerability and implement additional security measures, such as restricting access to critical configuration files.

The Quick Playground plugin for WordPress is vulnerable to Path Traversal in versions up to and including 1.3.3. This is due to insufficient path validation in the qckply_zip_theme() function, which appends a user-controlled 'stylesheet' parameter directly to the theme root directory path without sanitizing directory traversal sequences. This makes it possible for unauthenticated attackers to trigger the creation of a ZIP archive containing arbitrary files from the server's filesystem — including wp-config.
