{"id":"CVE-2026-44732","summary":"OpenProject: IDOR on OpenProject through /api/v3/documents/{id} via PATCH parameter \"project_id\" leads to Unauthorized Modification of Resources","details":"OpenProject is open-source, web-based project management software. Prior to 17.3.2 and 17.4.0, OpenProject exposes a document update endpoint used to modify existing documents. The target document is loaded with visibility checks and then updated. During update, attacker-controlled attributes are applied to the persisted record before authorization is enforced. As a result, a user without :manage_documents in the source project can move and modify foreign project documents by setting project_id in a single PATCH request. This vulnerability is fixed in 17.3.2 and 17.4.0.","aliases":["GHSA-mqvv-5mvc-7pg7"],"modified":"2026-07-15T01:49:21.641901665Z","published":"2026-06-26T19:39:58.895Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44732.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44732.json"},{"type":"ADVISORY","url":"https://github.com/opf/openproject/security/advisories/GHSA-mqvv-5mvc-7pg7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44732"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/opf/openproject","events":[{"introduced":"0"},{"fixed":"cd0d46e68f91e27deeb1fd12511a646043612498"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"fixed":"17.3.2"}]}}],"versions":["v17.3.1","11.2.1","v10.5","v9.0.0-pre","v5.0.4","sprint/2015_04","sprint/2015_03","sprint/2015_02","sprint/2015_01","sprint/2014_18","sprint/2014_16","sprint/2014_13","sprint/2014_12","sprint/2014_11","sprint/2014_10","sprint/2014_09","sprint/2014_08","2.4.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-44732.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"}]}
