CVE-2025-57521Public exploit

Local code execution via unsigned network plugin loading

Published Oct 21, 2025 · Updated Oct 21, 2025

Unsafe plugin loading in Bambu Lab Bambu Studio 2.1.1.52 and earlier allows local users to execute code at application startup. NetworkAgent loads a networking module from a user-writable location without confirming that its signing certificate matches the signed main executable. Write access to the expected plugin location is required, and injected code runs with the privileges of the user who launches the application.
