{"id":"CVE-2026-87013","summary":"Open WebUI: Any authenticated user can start a non-terminating request via a folder parent cycle","details":"Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.10.0 until 0.11.1, POST /api/v1/folders/{id}/update/parent allowed a user to place a folder under itself or one of its descendants, while the folder tree walks used by DELETE /api/v1/folders/{id} and POST /api/v1/folders/{id}/read did not track visited folder identifiers. An authenticated user could persist a parent cycle and start a request that consumed CPU and memory indefinitely, with the condition remaining stored until repaired. This issue is fixed in version 0.11.1.","aliases":["GHSA-8r35-5x5r-hv74"],"modified":"2026-09-12T03:30:45.492742712Z","published":"2026-09-09T21:00:15.466Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-835"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/87xxx/CVE-2026-87013.json"},"references":[{"type":"WEB","url":"https://github.com/open-webui/open-webui/releases/tag/v0.11.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/87xxx/CVE-2026-87013.json"},{"type":"ADVISORY","url":"https://github.com/open-webui/open-webui/security/advisories/GHSA-8r35-5x5r-hv74"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-87013"},{"type":"FIX","url":"https://github.com/open-webui/open-webui/commit/23b3a69bc26839bfa74edd1be6bfa2568ae902f4"},{"type":"FIX","url":"https://github.com/open-webui/open-webui/pull/28748"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/open-webui/open-webui","events":[{"introduced":"4d2e13cf2bcc451b33bb6374bea4d2163e6cc94c"},{"fixed":"23b3a69bc26839bfa74edd1be6bfa2568ae902f4"},{"fixed":"d3e8bf3405e848cfba377814d0aa7ba7290e414d"}],"database_specific":{"extracted_events":[{"introduced":"0.10.0"},{"fixed":"0.11.1"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v0.11.0","v0.10.2","v0.10.1","v0.10.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-87013.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L"}]}
