{"schema":"threatline.record/2","record":{"id":"CVE-2026-100108","aliases":[],"summary":"Social Share Buttons <= 1.30 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'share_url' Network Setting","details":"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.","categories":["Unclassified"],"product":"Social Share Buttons","vendor":"maxfoundry","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100108","source_modified_at":"2026-10-16T14:39:01.800Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Social Share Buttons","vendor":"maxfoundry","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.30","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.4,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00201,"percentile":0.09483,"score_date":"2026-10-23"},"published_at":"2026-10-16T07:44:03.268Z","modified_at":"2026-10-16T14:39:01.800Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-100108","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-16T14:39:01.800Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-100108","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/bc098f5d-3c59-4046-bce8-ac2586e6da19?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/share-button/tags/1.30/classes/class-social-networks.php#L370"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/share-button/tags/1.30/classes/blocks/network-block.php#L47"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/share-button/tags/1.30/classes/class-network.php#L275"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/share-button/tags/1.30/admin/review_notice.php#L26"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/share-button/tags/1.30/classes/class-social.php#L60"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3735252%40share-button&new=3735252%40share-button"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-16T14:33:43.282916Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-16T14:39:01.800Z","content_hash":"2b3299d9d3b2f8ef4343395f8a8b663db6098dfef000057509c93f7f7570233d"}}
