Authenticated SSRF via unvalidated Lighthouse base URL
Published Aug 12, 2026 · Updated Aug 12, 2026
Server-side request forgery in Prowler API before 5.33.1 allows remote authenticated users to reach arbitrary HTTP endpoints. The Lighthouse provider jobs pass an unvalidated openai_compatible base_url to an OpenAI client, whose models.list call sends the supplied API key in an Authorization header. Access to Lighthouse provider configuration is required; exploitation exposes the key to an attacker-controlled host or reaches internal services without granting host code execution.
