Plane · Plane · CVE-2026-105637
**Name of the Vulnerable Software and Affected Versions**
Plane versions prior to 1.4.0
**Description**
An issue exists in the `ProjectBulkAssetEndpoint.post` endpoint within `apps/api/plane/app/views/asset/v2.py` where assets are retrieved using `id in=asset ids` and `workspace slug=slug` without constraining the query by the `project id` provided in the URL. This allows a workspace Guest to provide asset UUIDs from a different project within the same workspace and reassign the `issue id`, `comment id`, `page id`, `draft issue id`, or `project id` to an entity controlled by the attacker. Consequently, the system recognizes the attacker's project as the new owner and generates a presigned download URL for the hijacked file.
**Recommendations**
Update to version 1.4.0.
