{"id":"CVE-2026-85286","summary":"HomeBox: Timing Side-Channel in Login Endpoint Allows User Enumeration via Bcrypt Hashing Delay","details":"HomeBox is a home inventory and organization system. Prior to 0.27.0, the POST /api/v1/users/login endpoint performs password-hash verification only when the submitted username matches an existing account, while unknown usernames return immediately. Although both paths return the same 401 unauthorized response, the processing-time discrepancy allows an unauthenticated remote attacker to distinguish registered email addresses; rate limiting only reduces the number of attempts per window. This issue is fixed in version 0.27.0.","aliases":["GHSA-4p8r-vm9v-c9pm"],"modified":"2026-11-05T21:32:25.371933713Z","published":"2026-11-05T16:01:52.991Z","database_specific":{"cwe_ids":["CWE-204","CWE-208"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/85xxx/CVE-2026-85286.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/85xxx/CVE-2026-85286.json"},{"type":"FIX","url":"https://github.com/sysadminsmedia/homebox/commit/66809ce3583cbd0b43e8f5ce30cc269a1cfe4201"},{"type":"WEB","url":"https://github.com/sysadminsmedia/homebox/releases/tag/v0.27.0"},{"type":"ADVISORY","url":"https://github.com/sysadminsmedia/homebox/security/advisories/GHSA-4p8r-vm9v-c9pm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-85286"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/sysadminsmedia/homebox","events":[{"introduced":"0"},{"fixed":"bae3fb4e9b84672e4e64da15e57a14217aea7c13"},{"fixed":"66809ce3583cbd0b43e8f5ce30cc269a1cfe4201"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"0"},{"fixed":"0.27.0"}],"source":"AFFECTED_FIELD","strategy":"StringRangeExpression"},{"range":[{"fixed":"66809ce3583cbd0b43e8f5ce30cc269a1cfe4201"}],"source":"REFERENCES_COMMIT"},{"source":"REFERENCES_TAG","original_tag":"v0.27.0","range":[{"fixed":"bae3fb4e9b84672e4e64da15e57a14217aea7c13"}]}]}}],"versions":["v0.26.2","v0.26.1","v0.26.0","v0.26.0-rc.1","v0.25.0","v0.25.0-rc.1","v0.24.2","v0.24.1","v0.24.0","v0.24.0-rc.1","v0.23.1","v0.23.0","v0.23.0-rc.1","v0.22.3","v0.22.2","v0.22.1","v0.22.0-rc.1","v0.21.0","v0.20.2","v0.20.1","v0.19.0","v0.18.0","v0.17.2","v0.17.1","v0.17.0","v0.16.0","v0.15.2","v0.15.1","v0.15.0","v0.14.2","v0.14.1","v0.14.0","v0.13.0","v0.12.1","v0.12.0","v0.11.1","v0.11.0","v0.9.2","v0.9.1","v0.9.0","v0.8.2","v0.8.1","v0.8.0","v0.7.0","v0.6.0","v0.5.1","v0.5.0","v0.4.0","v0.3.1","v0.3.0","v0.2.0","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-85286.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}
