CVE-2025-3805Public exploit

Local template injection via unsanitized ID

Published Apr 19, 2025 · Updated Apr 21, 2025

Server-side template injection in Tournatrack commit 4c13a23f43da5317eea4614870a7a8510fc540ec allows local users to alter rendered output. The check_id.py handler places an unvalidated ID request value into the Jinja2 template context, where crafted template syntax is evaluated during rendering. Low-privilege local access is required; successful injection can disclose or modify data and interrupt service.
