CVE-2026-92802 Details
Description
kan through 0.6.0 fails to properly validate board creation permissions in the GitHub project import endpoint, allowing guests to create boards despite lacking board:create permission. Attackers can bypass authorization checks by using the importProjects mutation to create boards while remaining blocked on direct creation paths.
A vulnerability in Kan versions through 0.6.0 allows guest users to create boards via the GitHub project import feature, bypassing the required permissions. This issue arises because the importProjects mutation only verifies if a user is a member of the workspace, rather than checking for the specific board:create permission. As a result, guests and members with revoked board creation rights can exploit this flaw to make unauthorized changes to the workspace.
The vulnerability can be addressed by updating the importProjects mutation to include a proper authorization check for the board:create permission, similar to the existing Trello import process.
