CVE-2026-105631

Plane is an open-source project management tool. Prior to 1.4.0, WorkspaceFileAssetEndpoint.get and WorkspaceAssetDownloadEndpoint.get resolve FileAsset records within a workspace without checking membership in the asset's project, allowing a workspace member to download assets from private projects when the asset UUID is known. EntityAssetEndpoint.get is a separate public-anchor endpoint that grants AllowAny access and scopes the lookup only to the anchor's workspace rather than its published entity or project. An unauthenticated caller who knows a valid anchor and an asset UUID can therefore retrieve issue-description or comment-description assets belonging to unpublished or private projects in that workspace. This issue is fixed in 1.4.0.
