  • Jun 6, 2026Quick Playground: Path TraversalCVE-2026-2500 · affects up to 1.3.4 · reported by WordfenceMedium 4.4

    The Quick Playground plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 1.3.4. This is due to the `qckply_data()` function passing the user-supplied `filename` POST parameter directly to `file_get_contents()` without any validation, sanitization, or path restriction. This makes it possible for authenticated attackers, with Administrator-level access and above, to read arbitrary files on the server, such as `wp-config.php` or `/etc/passwd`, which can contain sensitive information. Note: This vulnerability is only exploitable when the site has been synced with WordPress Playground (the `is_qckply_clone` option is set) or when running on `playground.wordpress.net`.

  • May 15, 2026Quick Playground: Path TraversalCVE-2026-6403 · affects up to 1.3.3 · reported by WordfenceHigh 7.5

    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.

  • Apr 9, 2026Quick Playground: Remote Code ExecutionCVE-2026-1830 · affects up to 1.3.1 · reported by WordfenceCritical 9.8

    The Quick Playground plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 1.3.1. This is due to insufficient authorization checks on REST API endpoints that expose a sync code and allow arbitrary file uploads. This makes it possible for unauthenticated attackers to retrieve the sync code, upload PHP files with path traversal, and achieve remote code execution on the server.
