{"schema":"threatline.record/2","record":{"id":"CVE-2026-105631","aliases":["GHSA-85h2-mhcc-xfmw"],"summary":"Plane: asset download endpoints scope file lookups to the workspace (not the project / published entity) → cross-project & unauthenticated private-file disclosure","details":"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a valid anchor and an asset UUID can therefore retrieve issue-description or comment-description assets belonging to unpublished or private projects in that workspace.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.","categories":["Unclassified"],"product":"plane","vendor":"makeplane","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-105631","source_modified_at":"2026-10-07T21:38:31.535Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"plane","vendor":"makeplane","versions":[{"status":"affected","version":"< 1.4.0"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/makeplane/plane/security/advisories/GHSA-85h2-mhcc-xfmw","source_modified_at":"2026-10-05T17:55:10Z","fetched_at":"2026-10-24T00:31:04.721601Z","package":{"ecosystem":"other","name":"makeplane/plane"},"range":"<= 1.3.1"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/makeplane/plane/security/advisories/GHSA-85h2-mhcc-xfmw","source_modified_at":"2026-10-05T17:55:10Z","fetched_at":"2026-10-24T00:31:04.721601Z","package":{"ecosystem":"other","name":"makeplane/plane"},"version":"1.4.0"}],"cvss":7.5,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00237,"percentile":0.13968,"score_date":"2026-10-23"},"published_at":"2026-10-05T17:55:56.166Z","modified_at":"2026-10-07T21:38:31.535Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-105631","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-07T21:38:31.535Z"},{"source":"GitHub Advisory Database","url":"https://github.com/makeplane/plane/security/advisories/GHSA-85h2-mhcc-xfmw","fetched_at":"2026-10-24T00:31:04.721601Z","source_modified_at":"2026-10-05T17:55:10Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-105631","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/makeplane/plane/security/advisories/GHSA-85h2-mhcc-xfmw","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/pull/9288","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/pull/9372","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/commit/4577dc3f7a6b5a198602b602a45c6b0abdc7204b","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/commit/e63f0c3b3404d669ae05dd9050aab72292f87e5c","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/releases/tag/v1.4.0","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-07T20:57:11.995552Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-07T21:38:31.535Z","content_hash":"dc8ce7ded264442d10b956ab214d0aecdf6d3e768a91add158d40ee225bcf2c8"}}
