CVE-2025-65519Public exploitNetwork attack vector

Authenticated service crash via unbounded import nesting

Published Feb 18, 2026 · Updated Feb 18, 2026

Uncontrolled recursion in mayswind ezBookkeeping 1.2.0 and earlier allows remote authenticated users to crash the service through file import. JSON import calls json.Unmarshal and XML import decoders call Decode without first limiting nesting depth, exhausting stack, CPU, and memory on deeply nested files. Any valid account can reach the HTTP import endpoint; demonstrated requests can saturate resources or crash the container until it is restarted.
