This is due to the method performing wp_insert_post() and update_post_meta() calls to create a sharing configuration without verifying the current user has administrator-level capabilities. This makes it possible for authenticated attackers, with Subscriber-level access and above, to trigger the creation of a published wpzoom-sharing configuration post with default sharing button settings, which causes social sharing buttons to be automatically injected into all post content on the frontend via the the_content filter."}], "title": "Social Icons Widget & Block <= 4.5.8 - Missing Authorization to Authenticated (Subscriber+) Sharing Configuration Creation", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/6af64b51-1758-495f-b6d7-364488de9ab8?source=cve"}, {"url": "https://plugins.trac.wordpress.org/browser/social-icons-widget-by-wpzoom/trunk/includes/classes/class-wpzoom-social-sharing-buttons.php#L110"}, {"url": "https://plugins.trac.wordpress.org/browser/social-icons-widget-by-wpzoom/tags/4.5.8/includes/classes/class-wpzoom-social-sharing-buttons.php#L110"}, {"url": "https://plugins.trac.wordpress.org/browser/social-icons-widget-by-wpzoom/tags/4.5.8/includes/classes/class-wpzoom-social-sharing-buttons.php#L134"}, {"url": "https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3481444%40social-icons-widget-by-wpzoom%2Ftrunk&old=3462717%40social-icons-widget-by-wpzoom%2Ftrunk&sfp_email=&sfph_mail="}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-862 Missing Authorization", "cweId": "CWE-862", "type": "CWE"}]}], "metrics": [{"cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N", "baseScore": 4.3, "baseSeverity": "MEDIUM"}}], "credits": [{"lang": "en", "type": "finder", "value": "darkestmode"}], "timeline": [{"time": "2026-03-12T19:20:35.000Z", "lang": "en", "value": "Vendor Notified"}, {"time": "2026-03-12T20:38:20.000Z", "lang": "en", "value": "Disclosed"}]}}}
