{"id":"CVE-2026-100108","published":"2026-10-16T08:17:12.320","lastModified":"2026-10-16T15:16:57.843","description":"The Social Share Buttons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'form (containing share_url)' parameter in all versions up to, and including, 1.30 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires that the 7-day review-nag timer has elapsed since the attacker's first wp-admin visit, as the nonce needed to reach the save-network handler is only rendered in the DOM once that timer has passed.","cvssScore":6.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://plugins.trac.wordpress.org/browser/share-button/tags/1.30/admin/review_notice.php#L26","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/share-button/tags/1.30/classes/blocks/network-block.php#L47","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/share-button/tags/1.30/classes/class-network.php#L275","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/share-button/tags/1.30/classes/class-social-networks.php#L370","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/share-button/tags/1.30/classes/class-social.php#L60","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3735252%40share-button&new=3735252%40share-button","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/bc098f5d-3c59-4046-bce8-ac2586e6da19?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
