This is due to insufficient input sanitization when saving via update_option() and lack of output escaping when displaying the stored value. The vulnerability exists in two locations: (1) the plugin settings page at inq_form.php line 180 where the value is echoed into an HTML attribute without esc_attr(), and (2) the front-end shortcode output at inquery_form_to_posts_or_pages.php line 139 where the value is output in HTML content without esc_html(). This makes it possible for authenticated attackers with administrator-level access to inject arbitrary web scripts that will execute whenever a user accesses the plugin settings page or views a page containing the [inquiry_form] shortcode."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Primary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:N", "baseScore": 4.4, "baseSeverity": "MEDIUM", "attackVector": "NETWORK", "attackComplexity": "HIGH", "privilegesRequired": "HIGH", "userInteraction": "NONE", "scope": "CHANGED", "confidentialityImpact": "LOW", "integrityImpact": "LOW", "availabilityImpact": "NONE"}, "exploitabilityScore": 1.3, "impactScore": 2.7}]}, "weaknesses": [{"source": "[email protected]", "type": "Primary", "description": [{"lang": "en", "value": "CWE-79"}]}], "references": [{"url": "https://plugins.trac.wordpress.org/browser/inquiry-form-to-posts-or-pages/tags/1.0/inq_form.php#L180", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/inquiry-form-to-posts-or-pages/tags/1.0/inq_form.php#L63", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/inquiry-form-to-posts-or-pages/tags/1.0/inquery_form_to_posts_or_pages.php#L139", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/inquiry-form-to-posts-or-pages/trunk/inq_form.php#L180", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/inquiry-form-to-posts-or-pages/trunk/inq_form.php#L63", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/inquiry-form-to-posts-or-pages/trunk/inquery_form_to_posts_or_pages.php#L139", "source": "[email protected]"}, {"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/743788ed-bd40-4eb4-a27e-d4eb89df3a41?source=cve", "source": "[email protected]"}]}}
