{"schema":"threatline.record/2","record":{"id":"CVE-2026-104960","aliases":["GHSA-wrrw-wvfv-67h7"],"summary":"Plane: Authorization bypass in workspace-scoped asset download endpoint exposes secret project file assets to non-project workspace users","details":"Plane is an open-source project management tool. Prior to 1.4.0, Plane exposes the workspace-scoped GET /api/assets/v2/workspaces/{workspace_slug}/download/{asset_id}/ endpoint for project-bound FileAsset objects without enforcing access to the asset's owning project. An authenticated user who belongs to the same workspace, is not a member of the victim's secret project, and knows the target asset UUID can receive a 302 redirect to a signed download URL. The intended project-scoped route for the same asset correctly returns 403. Confirmed affected project-bound asset types are ISSUE_ATTACHMENT, COMMENT_DESCRIPTION, PAGE_DESCRIPTION, and PROJECT_COVER. This bypass exposes private file content protected by the secret project boundary. 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-2026-104960","source_modified_at":"2026-10-05T17:51:34.599Z","fetched_at":"2026-10-23T18:52:38.922436Z","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-wrrw-wvfv-67h7","source_modified_at":"2026-10-05T16:47:44Z","fetched_at":"2026-10-23T21:14:28.314422Z","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-wrrw-wvfv-67h7","source_modified_at":"2026-10-05T16:47:44Z","fetched_at":"2026-10-23T21:14:28.314422Z","package":{"ecosystem":"other","name":"makeplane/plane"},"version":"1.4.0"}],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00318,"percentile":0.23496,"score_date":"2026-10-23"},"published_at":"2026-10-05T16:48:23.793Z","modified_at":"2026-10-05T17:51:34.599Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-104960","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-05T17:51:34.599Z"},{"source":"GitHub Advisory Database","url":"https://github.com/makeplane/plane/security/advisories/GHSA-wrrw-wvfv-67h7","fetched_at":"2026-10-23T21:14:28.314422Z","source_modified_at":"2026-10-05T16:47:44Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-104960","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-wrrw-wvfv-67h7","tags":["exploit"]},{"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/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":"2026-10-05T17:50:24.525391Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-05T17:51:34.599Z","content_hash":"b1204f605bc8bcc3833a5feb4262a92244b8be1883443c9423507ae7b492ca64"}}
