# CVE-2026-129430: axeloz filesharing before 2.14.3 Stored XSS via Bundle Description Markdown Links

Status: published. Published: 2026-11-14. Updated: 2026-11-14.

Axeloz Filesharing before 2.14.3 contains a stored cross-site scripting vulnerability that allows authenticated users to inject script by storing raw HTML or javascript: Markdown links in bundle descriptions. Recipients viewing the public bundle preview page execute the script via Alpine x-html, letting attackers steal the owner_token from localStorage and issue owner-scoped requests against victim bundles.
