CVE-2026-21856Public exploitNetwork attack vector

Database compromise via interpolated webhook identifier

Published Jan 7, 2026 · Updated Jan 7, 2026

SQL injection in The Hideout Tarkov Data Manager 2.0.0 and earlier allows remote authenticated users to execute arbitrary MySQL queries. The webhook edit route interpolates the URL path id directly into a WHERE clause, and the scanner API contains a similarly vulnerable query. An admin session and an existing webhook are required for the demonstrated request, which allows database data to be read, modified, or deleted.
