- Remediation
- ## Remediation Suggestions 1. Replace the proxy with the official, documented service endpoint and verify the intended model identifier. 2. Remove the API key and endpoint from source code. Load them from environment variables or a protected secrets manager. 3. Permit only explicitly approved HTTPS endpoints, preferably through a fixed allowlist. Reject malformed or unexpected endpoint overrides. 4. Display the exact destination host and request explicit user confirmation before uploading any local file. 5. Document which fields are transmitted, who operates the destination service, and the applicable retention, deletion, and privacy policies. 6. Use a narrowly scoped, revocable credential dedicated to this service. Never reuse credentials accepted by higher-value services. 7. Validate input files by permitted type and maximum size before reading or transmitting them. 8. Apply request timeouts and response-size limits, and validate returned image data before writing it to disk. 9. Rotate any real credentials previously used with this third-party endpoint if the operator's trustworthiness cannot be established.
