Users with read access to any knowledge base can supply a retained foreign directory UUID to GET /api/v1/knowledge/{id}/files. The returned breadcrumbs expose folder names, owner user ids and knowledge base ids of that directory and all its ancestors.","aliases":["GHSA-jx3w-3pqq-7f3w"],"modified":"2026-10-13T02:46:40.006941064Z","published":"2026-10-12T16:04:49.037Z","database_specific":{"cwe_ids":["CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/109xxx/CVE-2026-109287.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/109xxx/CVE-2026-109287.json"},{"type":"ADVISORY","url":"https://github.com/open-webui/open-webui/security/advisories/GHSA-jx3w-3pqq-7f3w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-109287"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/open-webui-0.9.6-before-0.11.4-information-disclosure-via-unscoped-directory-id"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/open-webui/open-webui","events":[{"introduced":"1a97751e376e00a1897bc3679215ae1c7bd8fd42"},{"fixed":"8bd8b4fac5e059578ac0c74b3c18d11139f88b7d"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0.9.6"},{"fixed":"0.11.4"}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-109287.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
