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a valid anchor and an asset UUID can therefore retrieve issue-description or comment-description assets belonging to unpublished or private projects in that workspace.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."}],"source":{"advisory":"GHSA-85h2-mhcc-xfmw","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/makeplane/plane/security/advisories/GHSA-85h2-mhcc-xfmw","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-10-07T20:57:11.995552Z","id":"CVE-2026-105631","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-07T21:38:31.535Z"}}]}}
