CVE-2026-123788 Details
Description
A security vulnerability has been detected in chenyme grok2api up to 3.1.6. The impacted element is an unknown function of the file backend/internal/transport/http/inference/voice_ws_handler.go of the component STT Billing. The manipulation leads to enforcement of behavioral workflow. The attack may be initiated remotely. Upgrading to version 3.1.7 is sufficient to resolve this issue. The identifier of the patch is 7ad0f791f0a9eb5a0ddfe38ac4dfcef01e19a6d4. Upgrading the affected component is recommended.
A vulnerability in Chenyme Grok2API versions through 3.1.6 allows clients to bypass billing for speech-to-text (STT) services. The issue arises in the STT Billing component, specifically within the voice WebSocket handler. When a client disconnects abnormally after receiving a transcription, the gateway fails to record the usage, creating a gap in billing accountability. This vulnerability can be exploited remotely by any user with a valid STT-capable API key.
Upgrading to Chenyme Grok2API version 3.1.7 addresses this vulnerability by ensuring that confirmed STT usage is billed correctly, regardless of how the WebSocket connection is closed.
