{"id":"CVE-2026-6403","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-6403","generatedAt":"2026-10-28T03:24:00.118Z","title":"The Quick Playground plugin for WordPress is vulnerable to Path Traversal in versions up to and including 1.3.3.","description":"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.","published":"2026-05-15T09:16:17.000Z","lastModified":"2026-06-17T11:00:47.000Z","status":"Deferred","sourceIdentifier":"security@wordfence.com","cvss":{"version":"3.1","score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-22"],"affected":[],"epss":{"score":0.00811,"percentile":0.56669,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.81%).
