CVE-2026-81662Network attack vector

Administrator-level code execution via unvalidated configuration keys

Published Aug 27, 2026 · Updated Aug 27, 2026

Code injection in Flowintel 3.3.0 and earlier allows remote authenticated users with administrator access to execute Python code. The alerts settings update endpoint inserts requester-controlled keys into assignment lines in conf/config_module.py and reloads that module without restricting key names. An administrator-level account is required; successful exploitation runs statements with the Flowintel server process's privileges and can read, alter, or interrupt application data and services.
