Detailsinfo

A vulnerability has been found in makeplane Plane up to 1.3.x and classified as problematic. This vulnerability affects an unknown functionality of the component Patch Handler. The manipulation of the argument issue_id with an unknown input leads to a access control vulnerability. The CWE definition for the vulnerability is CWE-284. The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. As an impact it is known to affect integrity, and availability. CVE summarizes:

Plane is an open-source project management tool. Prior to 1.4.0, the V2 issue-attachment PATCH endpoint accepts issue_id in the URL but omits it from the database query. A project member can use an issue_id they control in the URL while targeting another user's attachment by its pk UUID. Because the server matches only pk, workspace, and project_id, it modifies the attachment regardless of the issue_id in the URL. When the attachment is pending and has not been confirmed as uploaded, the PATCH handler sets created_by = request.user and transfers attachment ownership to the attacker. This issue is fixed in 1.4.0.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-105633 since 10/05/2026. The exploitation appears to be easy. The attack can be initiated remotely.
