Name of the Vulnerable Software and Affected Versions Quick Playground versions prior to 1.3.4
Description The Quick Playground plugin for WordPress contains a path traversal flaw. This occurs because the qckply zip theme() function fails to properly validate the stylesheet parameter, which is appended to the theme root directory path without sanitizing directory traversal sequences. Consequently, unauthenticated attackers can trigger the creation of a ZIP archive containing arbitrary files from the server's filesystem, such as the wp-config file.
Recommendations Update the plugin to a version later than 1.3.3. As a temporary workaround, restrict access to the qckply zip theme() function to minimize the risk of exploitation.
