Published Oct 5, 2026 · Updated Oct 5, 2026 · Assigned by GitHub_M

Description

Plane is an open-source project management tool. Prior to 1.4.0, the modules endpoint accepts issue UUIDs in the URL path without validating that they belong to the caller's workspace. An authenticated user can link issues from any workspace to modules in their own workspace. This issue is fixed in 1.4.0.
