Summary

easyVoice before 0.0.23 contains a server-side request forgery flaw, tracked as CWE-918, in which the server does not restrict the target of requests built from user input. With useLLM enabled, an unauthenticated remote attacker can supply openaiBaseUrl to make the server send POST requests to loopback and internal services through the /api/v1/tts endpoints. Reflected error messages in the x-generate-tts-warning header let the attacker probe internal hosts and ports.
