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. The injected payload is stored in the gs-alert-msg, gs-alert-utm, and gs-alert-cta WordPress options and executes in an administrator's browser when the GetSocial settings page is visited.","state":0,"publishedAt":"2026-10-14T04:28:11.302+00:00","modifiedAt":"2026-10-14T14:22:44.025+00:00","affected":[{"ecosystem":"Vendor product","name":"Social Share Buttons & Analytics Plugin – GetSocial.io","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"joaoromao\",\n                    \"product\": \"Social Share Buttons & Analytics Plugin – GetSocial.io\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"4.5\",\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/86f9c68f-73ab-4f2b-8424-8515cdf82577?source=cve","https://plugins.trac.wordpress.org/browser/wp-share-buttons-analytics-by-getsocial/tags/4.5/tmpl/alerts.php#L18","https://plugins.trac.wordpress.org/browser/wp-share-buttons-analytics-by-getsocial/tags/4.5/wp-share-buttons-analytics-getsocial.php#L54","https://plugins.trac.wordpress.org/browser/wp-share-buttons-analytics-by-getsocial/tags/4.5/lib/gs.php#L72","https://plugins.trac.wordpress.org/browser/wp-share-buttons-analytics-by-getsocial/tags/4.5/wp-share-buttons-analytics-getsocial.php#L38"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-103369","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-103369","identifiers":["CVE-2026-103369"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
