| Название | Simular AI Agent-S 0.3.2 Denial of Service |
|---|
| Описание | Agent-S contains a denial of service vulnerability in its OCR HTTP API. The /ocr/ endpoint accepts an unauthenticated JSON body with an img_bytes field, but does not enforce Content-Length, encoded field size, decoded byte size, image pixel count, or OCR execution limits before FastAPI/Pydantic reads and materializes the request body.
An attacker can send a single oversized OCR request that forces the service to buffer and process excessive attacker-controlled input before rejection. In a deployed environment, this can exhaust OCR worker memory, terminate the container, and make OCR-backed agent functionality unavailable to legitimate users. |
