This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:N","score":4.4},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/facebook-auto-publish/tags/2.4.11/admin/ajax-actions.php#L39","https://plugins.trac.wordpress.org/browser/facebook-auto-publish/tags/2.4.11/admin/ajax-actions.php#L46","https://plugins.trac.wordpress.org/browser/facebook-auto-publish/tags/2.4.11/admin/settings.php#L534","https://plugins.trac.wordpress.org/browser/facebook-auto-publish/tags/2.4.12/admin/ajax-actions.php#L39","https://plugins.trac.wordpress.org/browser/facebook-auto-publish/tags/2.4.12/admin/ajax-actions.php#L46"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-12042","score":0.00335,"percentile":0.26879,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
