{"schema":"threatline.record/2","record":{"id":"CVE-2026-104956","aliases":["GHSA-wwgj-929g-42cm"],"summary":"Plane: Unauthenticated ORM field-name injection via `group_by`/`sub_group_by` on public deploy boards (DoS + blind oracle)","details":"Plane is an open-source project management tool. Prior to 1.4.0, the unauthenticated public issues endpoint accepts group_by and sub_group_by query parameters and passes them without an allowlist to grouped paginators, where they are used as ORM field names by F(field), .values(field), .order_by(field), and Window partition_by operations. An anonymous attacker can supply arbitrary field paths that trigger an unhandled FieldError or KeyError and an HTTP 500 response, or force the ORM to resolve __-separated relational paths as a blind traversal oracle. This is the same field-name injection class addressed by earlier order_by sanitization, but that remediation left group_by and sub_group_by unvalidated. The issue does not directly disclose column values because issue_group_values() returns an empty list for unknown fields, the result projection uses a fixed required_fields list, and the subgrouped path raises KeyError before serialization. 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-2026-104956","source_modified_at":"2026-10-05T19:16:13.732Z","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-wwgj-929g-42cm","source_modified_at":"2026-10-05T16:43:16Z","fetched_at":"2026-10-23T19:58:35.668311Z","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-wwgj-929g-42cm","source_modified_at":"2026-10-05T16:43:16Z","fetched_at":"2026-10-23T19:58:35.668311Z","package":{"ecosystem":"other","name":"makeplane/plane"},"version":"1.4.0"}],"cvss":5.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00379,"percentile":0.30721,"score_date":"2026-10-23"},"published_at":"2026-10-05T16:47:10.263Z","modified_at":"2026-10-05T19:16:13.732Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-104956","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-05T19:16:13.732Z"},{"source":"GitHub Advisory Database","url":"https://github.com/makeplane/plane/security/advisories/GHSA-wwgj-929g-42cm","fetched_at":"2026-10-23T19:58:35.668311Z","source_modified_at":"2026-10-05T16:43:16Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-104956","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-wwgj-929g-42cm","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/pull/9347","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/makeplane/plane/commit/d3d3de44cf13991025783c598d8b34229fb47729","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":"yes","technical_impact":"partial","assessed_at":"2026-10-05T19:15:53.218416Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-05T19:16:13.732Z","content_hash":"3ecd98788f756edcd8c3e5398ac47364e3278693a50e02e043990133446ae0a7"}}
