From 0.6.27 before 0.10.0, get_all_models handlers in routers/openai.py and routers/ollama.py passed a lambda to aiocache key instead of key_builder, causing permission-filtered per-user model lists to share a static cache entry and exposing one user’s model list to another caller during the TTL window. This issue is fixed in version 0.10.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N","score":5.0},"cwes":["CWE-524"],"references":["https://github.com/open-webui/open-webui/commit/0fc630b34b2899599dabffffa012afd47599aa75","https://github.com/open-webui/open-webui/pull/25783","https://github.com/open-webui/open-webui/releases/tag/v0.10.0","https://github.com/open-webui/open-webui/security/advisories/GHSA-3wp3-xxj9-5jqq","https://github.com/open-webui/open-webui/security/advisories/GHSA-3wp3-xxj9-5jqq"],"products":["openwebui:open_webui"],"source":"nvd","synced_at":"2026-10-19T22:44:02.134301115+00:00"},"epss":{"cve":"CVE-2026-59213","score":0.00373,"percentile":0.3124,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-3wp3-xxj9-5jqq","url":"https://osv.dev/vulnerability/GHSA-3wp3-xxj9-5jqq","summary":"Open WebUI: Cross-user model-list exposure via static cache key in get_all_models (aiocache key= vs key_builder= misuse)","modified":"2026-08-04T14:40:49.140511052Z","packages":[{"ecosystem":"PyPI","name":"open-webui","purl":"pkg:pypi/open-webui","ranges":[">=0.6.27 <0.10.0"],"fixed":["0.10.0"]}]},{"id":"PYSEC-2026-3589","url":"https://osv.dev/vulnerability/PYSEC-2026-3589","summary":"Open WebUI: Cross-user model-list exposure via static cache key in get_all_models (aiocache key= vs key_builder= misuse)","modified":"2026-08-04T14:30:27.761957465Z","packages":[{"ecosystem":"PyPI","name":"open-webui","purl":"pkg:pypi/open-webui","ranges":[">=0.6.27 <0.10.0"],"fixed":["0.10.0"]}]}],"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).
