{"id":"CVE-2026-47159","summary":"Vaultwarden: Authentication Flow Information Disclosure in SSO Discovery Allows Organization Enumeration and Pre-Validation Token Exposure","details":"Vaultwarden is a Bitwarden-compatible server written in Rust. Prior to 1.36.0, Vaultwarden's SSO discovery and pre-validation flow returned organization-related SSO metadata including organizationIdentifier values for arbitrary email addresses and allowed a valid pre-validation JWT to be obtained with only the discovered identifier, enabling SSO-enabled organization enumeration and authentication workflow abuse. This issue is fixed in version 1.36.0.","aliases":["GHSA-hxqh-ff5p-wfr3"],"modified":"2026-07-17T03:45:43.014046671Z","published":"2026-07-15T15:02:46.349Z","database_specific":{"cwe_ids":["CWE-287"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47159.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/dani-garcia/vaultwarden/releases/tag/1.36.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47159.json"},{"type":"ADVISORY","url":"https://github.com/dani-garcia/vaultwarden/security/advisories/GHSA-hxqh-ff5p-wfr3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47159"},{"type":"FIX","url":"https://github.com/dani-garcia/vaultwarden/commit/d297e274a35dccd0f5d935e9d5934e0f7e9c0a87"},{"type":"FIX","url":"https://github.com/dani-garcia/vaultwarden/pull/7163"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dani-garcia/vaultwarden","events":[{"introduced":"0"},{"fixed":"d297e274a35dccd0f5d935e9d5934e0f7e9c0a87"},{"fixed":"f21a3adae2fbb8582b60b121783c597fe6895ff4"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.36.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["1.35.8","1.35.7","1.35.6","1.35.5","1.35.4","1.35.3","1.35.2","1.35.1","1.35.0","1.34.3","1.34.2","1.34.1","1.34.0","1.33.2","1.33.1","1.33.0","1.32.7","1.32.6","1.32.5","1.32.4","1.32.3","1.32.2","1.32.1","1.32.0","1.31.0","1.30.5","1.30.4","1.30.3","1.30.2","1.30.1","1.30.0","1.29.2","1.29.1","1.29.0","1.28.1","1.28.0","1.27.0","1.26.0","1.25.2","1.25.1","1.25.0","1.24.0","1.23.1","1.23.0","1.22.2","1.22.1","1.22.0","1.21.0","1.20.0","1.19.0","1.18.0","1.17.0","1.16.3","1.16.2","1.16.1","1.16.0","1.15.1","1.15.0","1.14.2","1.14.1","1.14","1.13.1","1.13.0","1.12.0","1.11.0","1.10.0","1.9.1","1.9.0","1.8.0","1.7.0","1.6.1","1.6.0","1.5.0","1.4.0","1.3.0","1.2.0","1.1.0","1.0.0","0.13.0","0.12.0","0.11.0","0.10.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-47159.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
