- Remediation
- <![CDATA[ ## Remediation Suggestions 1. Replace `api.chatfire.site` with the documented official provider endpoint, unless the third-party service is explicitly intended and trusted. 2. Clearly disclose every domain that receives credentials, prompts, image URLs, and request metadata before execution. 3. Require credentials issued specifically for the actual destination service rather than forwarding credentials represented as belonging to another provider. 4. Use narrowly scoped, short-lived tokens restricted to image-generation operations and appropriate spending limits. 5. Implement a hardcoded or securely configured endpoint allowlist. Reject unapproved schemes, hosts, redirects, and endpoint overrides. 6. Disable automatic cross-origin redirects for authenticated requests, or ensure authorization headers are never forwarded to a different host. 7. Provide explicit user confirmation before transmitting sensitive prompts or image references to a third party. 8. Document credential revocation procedures and advise existing users to rotate any key already supplied to these scripts. ]]>
