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.","state":0,"publishedAt":"2026-10-16T07:44:03.268+00:00","modifiedAt":"2026-10-16T14:39:01.8+00:00","affected":[{"ecosystem":"Vendor product","name":"Social Share Buttons","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"maxfoundry\",\n                    \"product\": \"Social Share Buttons\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"1.30\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4,"severity":"MEDIUM"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/bc098f5d-3c59-4046-bce8-ac2586e6da19?source=cve","https://plugins.trac.wordpress.org/browser/share-button/tags/1.30/classes/class-social-networks.php#L370","https://plugins.trac.wordpress.org/browser/share-button/tags/1.30/classes/blocks/network-block.php#L47","https://plugins.trac.wordpress.org/browser/share-button/tags/1.30/classes/class-network.php#L275","https://plugins.trac.wordpress.org/browser/share-button/tags/1.30/admin/review_notice.php#L26","https://plugins.trac.wordpress.org/browser/share-button/tags/1.30/classes/class-social.php#L60","https://plugins.trac.wordpress.org/changeset?reponame=&old=3735252%40share-button&new=3735252%40share-button"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-100108","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-100108","identifiers":["CVE-2026-100108"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
