CVE-2025-14202Network attack vector

Admin account takeover via unsandboxed SVG rendering

Published Dec 17, 2025 · Updated Dec 17, 2025

Stored XSS in linkding 1.44.1 allows remote authenticated users to take over an administrator account through a shared SVG asset. The asset-serving route returns uploaded SVG content without a sandbox Content Security Policy, allowing embedded scripts to run in linkding's origin, read the CSRF token, and submit a password change. Exploitation requires a remote authenticated user to upload the SVG and an administrator to view it; success compromises that administrator account.
