This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the 'Parse Vimeo and YouTube links' option to be enabled and a site administrator to approve the comment containing the malicious shortcode; execution is then triggered for any visitor who interacts with the video player on that page.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:N","score":5.4},"cwes":["CWE-79"],"references":["https://github.com/foliovision/fv-wordpress-flowplayer/commit/62aaa66a560923a4ba75f5d0a557744599345d35","https://plugins.trac.wordpress.org/browser/fv-wordpress-flowplayer/trunk/controller/frontend.php#L664","https://plugins.trac.wordpress.org/browser/fv-wordpress-flowplayer/trunk/flowplayer/modules/ad-popup.module.js#L39","https://plugins.trac.wordpress.org/browser/fv-wordpress-flowplayer/trunk/models/flowplayer-frontend.php#L684","https://plugins.trac.wordpress.org/browser/fv-wordpress-flowplayer/trunk/models/flowplayer-frontend.php#L829"],"products":[],"source":"nvd","synced_at":"2026-10-30T19:40:38.187835185+00:00"},"epss":null,"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).
