PraisonAI Platform is the platform layer for the PraisonAI multi-agent teams system. Versions prior to 0.1.4 have an insecure default cryptographic key. The JWT signing secret defaults to the hardcoded literal ""dev-secret-change-me"" when "PLATFORM_JWT_SECRET" is unset. A safety check exists but only fires when "PLATFORM_ENV != "dev""; the default value of "PLATFORM_ENV" is ""dev"", so the check is silently bypassed in any deployment that does not explicitly opt out. The attacker reads the literal from this public source file, mints a JWT with arbitrary "sub" and "email" claims, and authenticates as any existing user (including workspace owners and admins). PraisonAI Platform version 0.1.4 patches the issue.
