Prevents sending the Authorization header when downloading env packages from URLs that don't match the trusted API host.
Note
Medium Risk
Tightens authentication header handling in environment downloads, which can affect access to private env artifacts if download URLs are not HTTPS or don’t match the configured API host. Also changes tar extraction behavior to fail on additional validation errors.
Overview
Prevents leaking credentials during
prime env pulland private env downloads by only attaching theAuthorizationheader when thedownload_urlis HTTPS and matches the configured API host (_is_trusted_url).Switches archive extraction in
pullto use_safe_tar_extractand treats validation failures (ValueError) as extraction errors, improving protection against malicious tar contents.Reviewed by Cursor Bugbot for commit c8118f3. Bugbot is set up for automated code reviews on this repo. Configure here.
