CVE-2026-11402Network attack vector

Contributor-level stored XSS via unescaped link attribute

Published Jun 18, 2026 · Updated Jun 18, 2026

Stored XSS in bPlugins Services Section Block 1.4.4 and earlier allows remote authenticated users to inject scripts via a link attribute. The block stores the link value inside post_content HTML comments without sufficient sanitization, then places it unescaped into primary and title-wrapped anchors during rendering. Contributor-level access is required to plant the payload, which executes in the browser of anyone who opens the affected page and can act within that viewer's session.
