{"id":"CVE-2025-11161","state":"PUBLISHED","title":"WPBakery Page Builder <= 8.6.1 - Stored Cross-Site Scripting via vc_custom_heading Shortcode","description":"The WPBakery Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the vc_custom_heading shortcode in all versions up to, and including, 8.6.1. This is due to insufficient restriction of allowed HTML tags and improper sanitization of user-supplied attributes in the font_container parameter. This makes it possible for authenticated attackers with contributor-level access or higher to inject arbitrary web scripts in posts that will execute whenever a user accesses an injected page via the vc_custom_heading shortcode with malicious tag and text attributes granted they have access to use WPBakery shortcodes.","publishedAt":"2025-10-15T06:43:56.365Z","updatedAt":"2026-04-08T16:42:55.440Z","severity":{"score":6.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["wpbakery WPBakery Page Builder"],"affected":[{"vendor":"wpbakery","product":"WPBakery Page Builder","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"8.6.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/2772cade-c625-437a-b57b-ce8a2e3393bf?source=cve","http://kb.wpbakery.com/docs/preface/release-notes/"],"weaknesses":["CWE-80"],"ingestedAt":"2026-10-29T20:08:31.050Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/11xxx/CVE-2025-11161.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-11161","state":"PUBLISHED","datePublished":"2025-10-15T06:43:56.365Z","dateUpdated":"2026-04-08T16:42:55.440Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2025-09-29T15:17:13.737Z"},"containers":{"cna":{"title":"WPBakery Page Builder <= 8.6.1 - Stored Cross-Site Scripting via vc_custom_heading Shortcode","descriptions":[{"lang":"en","value":"The WPBakery Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the vc_custom_heading shortcode in all versions up to, and including, 8.6.1.
