🛠 Guidelines to remediate hardcoded secrets
- Understand the implications of revoking this secret by investigating where it is used in your code.
- Replace and store your secret safely. Learn here the best practices.
- Revoke and rotate this secret.
- If possible, rewrite git history. Rewriting git history is not a trivial act. You might completely break other contributing developers' workflow and you risk accidentally deleting legitimate data.
To avoid such incidents in the future consider
- following these best practices for managing and storing secrets including API keys and other credentials
- install secret detection on pre-commit to catch secret before it leaves your machine and ease remediation.

CORS misconfiguration for credentials transfer High

To resolve this, always ensure that when Access-Control-Allow-Credentials is enabled and user credentials may be transmitted, the value set in Access-Control-Allow-Origin comes from a hardcoded, source-controlled whitelist — never from a dynamic or user-controlled value (including environment variables).
Approach:
- Only set
Access-Control-Allow-Originto the incoming request origin if it matches a source-controlled whitelist (here,TRUSTED_ORIGINS_FOR_CREDENTIALS) and credentials are allowed. - If the request origin is allowed but not trusted-for-credentials, set the header without
Access-Control-Allow-Credentials, or respond with an error or a safe fallback value. - Ensure that origins from environment variables (
CONFIG.CORS_ORIGINS) are only allowed without credentials, and never for credentialed responses. - All handling should be done inside the server request handler.
Changes needed:
- Edit the CORS logic in the request handler (lines 660-685) so that:
- If
originis inTRUSTED_ORIGINS_FOR_CREDENTIALS, set bothAccess-Control-Allow-OriginandAccess-Control-Allow-Credentials: true. - If
originis inCONFIG.CORS_ORIGINSbut not inTRUSTED_ORIGINS_FOR_CREDENTIALS, set onlyAccess-Control-Allow-Origin, neverAccess-Control-Allow-Credentials: true. - If
originis not in either list, do not set any CORS headers (or you may respond with a CORS error).
- If
- No new imports are needed; all code changes are limited to the handler in
api-dev-server.ts.
