CVE-2026-22867Network attack vector

Stored XSS via unvalidated interlink URL

Published Jan 15, 2026 · Updated Jan 15, 2026

Stored XSS in La Suite numérique Docs 3.8.0 through 4.3.0 allows remote authenticated users to run script in another user's browser. InterlinkingLinkInlineContent.handleClick passes an editor-controlled stored URL directly to Next.js router.push, which executes javascript: URLs. Document-edit privileges are required to plant the link, and a victim must click it; the script can read and alter accessible documents and replicate into editable documents.
