CVE-2025-4430Network attack vector

Authenticated file manipulation via token endpoint authorization bypass

Published May 14, 2025 · Updated May 14, 2025

Missing authorization in EZD RP before 20.19 allows remote authenticated users to manipulate files through the token API. The /api/Token/gettoken endpoint permits an unauthorized request instead of enforcing the required access-control check. Low-privilege credentials and network reachability are sufficient; public sources do not specify which files or operations are exposed.
