What is CVE-2026-42869?
CVE-2026-42869 is a critical vulnerability in socfortress CoPilot, published on 11 May 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
SOCFortress CoPilot focuses on providing a single pane of glass for all your security operations needs. Prior to 0.1.57, SOCFortress CoPilot ships a hardcoded JWT signing secret as a fallback value in backend/app/auth/utils.py:28 and ships it verbatim in .env.example. Any deployment where JWT_SECRET is not explicitly set — including the default Docker Compose setup — signs all authentication tokens with this publicly known value. An unauthenticated attacker can forge arbitrary admin-scoped JWTs and gain full control of the application and every security tool it manages without any credentials. This vulnerability is fixed in 0.1.57.
