OpenMAIC before 1.0.1 SSRF via Environment-Gated URL Validation
OpenMAIC before 1.0.1 skips server-side request forgery validation in non-production builds, allowing unauthenticated attackers to reach cloud instance metadata services. Attackers can supply arbitrary provider URLs via the x-base-url header or baseUrl parameter to access sensitive cloud credentials and metadata.
