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."}],"title":"Social Share Buttons <= 1.30 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'share_url' Network Setting","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/bc098f5d-3c59-4046-bce8-ac2586e6da19?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/share-button/tags/1.30/classes/class-social-networks.php#L370"},{"url":"https://plugins.trac.wordpress.org/browser/share-button/tags/1.30/classes/blocks/network-block.php#L47"},{"url":"https://plugins.trac.wordpress.org/browser/share-button/tags/1.30/classes/class-network.php#L275"},{"url":"https://plugins.trac.wordpress.org/browser/share-button/tags/1.30/admin/review_notice.php#L26"},{"url":"https://plugins.trac.wordpress.org/browser/share-button/tags/1.30/classes/class-social.php#L60"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3735252%40share-button&new=3735252%40share-button"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","cweId":"CWE-79","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"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"}}],"credits":[{"lang":"en","type":"finder","value":"chimerascope"}],"timeline":[{"time":"2026-09-30T15:30:13.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-10-15T19:41:23.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-100108","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-10-16T14:33:43.282916Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-16T14:39:01.800Z"}}]}}
