CVE-2025-50739Public exploitNetwork attack vector

Unauthenticated code execution via unsafe JSON deserialization

Published Oct 30, 2025 · Updated Oct 30, 2025

Code injection in iib0011 omni-tools 0.4.0 allows remote attackers to execute arbitrary code through the JSON Stringify endpoint. The published record attributes the flaw to unsafe JSON deserialization, but public sources identify neither the deserializer nor the exact operation that turns input into executable code. The endpoint is reachable over the network without authentication or user interaction, and successful exploitation runs code in the application's security context.
