The permission check performed when a user pushes to a project repository did not correctly evaluate the required access level, so the check passed for any user holding any level of access to the project. As a result, an authenticated user with view-only access to a project could write to that project's git repository.\n\n\n\n\nRead access was evaluated correctly and was not affected, and exploitation requires an authenticated account with existing access to the target project. The issue has been remediated in Altium 365 at the service level and no customer action is required. On-premise Altium Enterprise Server is not affected.\n\n## Affected\n\n- `365 unspecified`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":40,"depthScoreParts":{"impact":39.6,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
