1) Improper Authorization (CVE-ID: N/A)

CWE-ID: CWE-285 - Improper Authorization

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to create repositories in an organization without authorization.

The vulnerability exists due to improper access control in the fork repository API endpoint when handling fork requests into organizations. A remote user can send a specially crafted API request to create repositories in an organization without authorization.

The issue affects POST /api/v1/repos/{owner}/{repo}/forks because it checks organization membership but does not verify whether repository creation is permitted for that user in the target organization.
