Description

easyVoice before 0.0.23 contains a server-side request forgery vulnerability that allows unauthenticated attackers to make the server send POST requests by supplying openaiBaseUrl with useLLM enabled. Attackers can target loopback and internal services through /api/v1/tts endpoints, using reflected error messages in the x-generate-tts-warning header to probe internal hosts and ports.
