{"cve":"CVE-2026-54012","nvd":{"published":"2026-06-23T18:18:06.443","modified":"2026-06-25T13:26:51.623","status":"Analyzed","description":"Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.6, Open WebUI lets a user who can create, update, or import workspace models store arbitrary meta.knowledge entries on their model without checking whether they own or can read the referenced files. Open WebUI then treats meta.knowledge entries of type file as an authorization source in two places: the built-in view_file tool reads the file's extracted text, and has_access_to_file()'s model branch authorizes the file content and file delete endpoints. A malicious model owner can therefore attach another user's file ID to their model metadata and read or delete that private file. This vulnerability is fixed in 0.9.6.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:L","score":7.1},"cwes":["CWE-284","CWE-285","CWE-862"],"references":["https://github.com/open-webui/open-webui/security/advisories/GHSA-vjqm-6gcc-62cr","https://github.com/open-webui/open-webui/security/advisories/GHSA-vjqm-6gcc-62cr"],"products":["openwebui:open_webui"],"source":"nvd","synced_at":"2026-10-19T22:41:17.107060303+00:00"},"epss":{"cve":"CVE-2026-54012","score":0.00325,"percentile":0.25554,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-vjqm-6gcc-62cr","url":"https://osv.dev/vulnerability/GHSA-vjqm-6gcc-62cr","summary":"Open WebUI: Forged model meta.knowledge allows cross-user file read and deletion","modified":"2026-07-20T21:15:24.544200781Z","packages":[{"ecosystem":"PyPI","name":"open-webui","purl":"pkg:pypi/open-webui","ranges":["<0.9.6"],"fixed":["0.9.6"]}]},{"id":"PYSEC-2026-2761","url":"https://osv.dev/vulnerability/PYSEC-2026-2761","summary":"Open WebUI: Forged model meta.knowledge allows cross-user file read and deletion","modified":"2026-07-13T16:32:25.004494539Z","packages":[{"ecosystem":"PyPI","name":"open-webui","purl":"pkg:pypi/open-webui","ranges":["<0.9.6"],"fixed":["0.9.6"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
