The flaw stems from trusting client-supplied GitLab provider configuration in the POST /api/auth/login/GITLAB_SELF_HOST endpoint. Attackers can set instanceUrl to a server they control that returns an active user with a chosen email. Bytebase then issues session tokens for that principal, letting attackers impersonate existing users including the Owner or create new members.","state":0,"publishedAt":"2026-10-22T19:17:30.883+00:00","modifiedAt":"2026-10-23T19:57:42.66+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · disclosure@vulncheck.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":9.3,"severity":"CRITICAL"},{"system":"CVSS 3.1 · disclosure@vulncheck.com · Primary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://github.com/bytebase/bytebase","https://github.com/bytebase/bytebase/blob/1.0.0/server/auth.go#L79-L93","https://github.com/bytebase/bytebase/commit/d69e682243b25b51dd52912a26e2f259b5f3db2d","https://github.com/bytebase/bytebase/pull/834","https://github.com/bytebase/bytebase/releases/tag/1.0.1","https://github.com/bytebase/bytebase/security/advisories/GHSA-5r3p-6rj5-7937","https://www.vulncheck.com/advisories/bytebase-0.12.0-before-1.0.1-authentication-bypass-via-gitlab-self-hosted-login"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2022-51026","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-290"],"productCriteria":[],"sourceDates":{"published":"2026-10-22T19:17:30.883","lastModified":"2026-10-23T19:57:42.660"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
