{"id":"CVE-2026-4063","state":"PUBLISHED","title":"Social Icons Widget & Block <= 4.5.8 - Missing Authorization to Authenticated (Subscriber+) Sharing Configuration Creation","description":"The Social Icons Widget & Block by WPZOOM plugin for WordPress is vulnerable to unauthorized data modification due to a missing capability check in the add_menu_item() method hooked to admin_menu in all versions up to, and including, 4.5.8. 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.","publishedAt":"2026-03-13T09:25:00.829Z","updatedAt":"2026-04-08T16:58:55.714Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["wpzoom Social Icons Widget & Block – Social Media Icons & Share Buttons"],"affected":[{"vendor":"wpzoom","product":"Social Icons Widget & Block – Social Media Icons & Share Buttons","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.5.8","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/6af64b51-1758-495f-b6d7-364488de9ab8?source=cve","https://plugins.trac.wordpress.org/browser/social-icons-widget-by-wpzoom/trunk/includes/classes/class-wpzoom-social-sharing-buttons.php#L110","https://plugins.trac.wordpress.org/browser/social-icons-widget-by-wpzoom/tags/4.5.8/includes/classes/class-wpzoom-social-sharing-buttons.php#L110","https://plugins.trac.wordpress.org/browser/social-icons-widget-by-wpzoom/tags/4.5.8/includes/classes/class-wpzoom-social-sharing-buttons.php#L134","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="],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4063.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4063","state":"PUBLISHED","datePublished":"2026-03-13T09:25:00.829Z","dateUpdated":"2026-04-08T16:58:55.714Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-12T17:32:50.022Z"},"containers":{"cna":{"title":"Social Icons Widget & Block <= 4.5.8 - Missing Authorization to Authenticated (Subscriber+) Sharing Configuration Creation","descriptions":[{"lang":"en","value":"The Social Icons Widget & Block by WPZOOM plugin for WordPress is vulnerable to unauthorized data modification due to a missing capability check in the add_menu_item() method hooked to admin_menu in all versions up to, and including, 4.5.8.
