{"id":"CVE-2026-104956","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-104956","generatedAt":"2026-10-28T04:18:29.090Z","title":"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),…","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.","published":"2026-10-05T17:17:11.000Z","lastModified":"2026-10-05T20:17:10.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},"cwe":["CWE-943"],"affected":[],"epss":{"score":0.00379,"percentile":0.31738,"date":"2026-10-27","history":[{"date":"2026-10-06","score":0.00379,"percentile":0.29688}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.38%).
