{"id":"CVE-2026-104956","state":"PUBLISHED","title":"Plane: Unauthenticated ORM field-name injection via `group_by`/`sub_group_by` on public deploy boards (DoS + blind oracle)","description":"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.","publishedAt":"2026-10-05T16:47:10.263Z","updatedAt":"2026-10-05T19:16:13.732Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["makeplane plane"],"affected":[{"vendor":"makeplane","product":"plane","versions":[{"version":"< 1.4.0","status":"affected"}]}],"references":["https://github.com/makeplane/plane/security/advisories/GHSA-wwgj-929g-42cm","https://github.com/makeplane/plane/pull/9347","https://github.com/makeplane/plane/commit/d3d3de44cf13991025783c598d8b34229fb47729","https://github.com/makeplane/plane/releases/tag/v1.4.0"],"weaknesses":["CWE-943"],"ingestedAt":"2026-10-29T20:10:23.711Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/104xxx/CVE-2026-104956.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-104956","state":"PUBLISHED","datePublished":"2026-10-05T16:47:10.263Z","dateUpdated":"2026-10-05T19:16:13.732Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-10-02T18:16:13.628Z"},"containers":{"cna":{"title":"Plane: Unauthenticated ORM field-name injection via `group_by`/`sub_group_by` on public deploy boards (DoS + blind oracle)","descriptions":[{"lang":"en","value":"Plane is an open-source project management tool.
