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":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","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","score":9.3,"severity":null}],"references":["https://github.com/bytebase/bytebase/security/advisories/GHSA-5r3p-6rj5-7937","https://github.com/bytebase/bytebase/commit/d69e682243b25b51dd52912a26e2f259b5f3db2d","https://github.com/bytebase/bytebase/pull/834","https://github.com/bytebase/bytebase/blob/1.0.0/server/auth.go#L79-L93","https://github.com/bytebase/bytebase/releases/tag/1.0.1","https://github.com/bytebase/bytebase","https://www.vulncheck.com/advisories/bytebase-0.12.0-before-1.0.1-authentication-bypass-via-gitlab-self-hosted-login"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2022-56076","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 22, 2026, 7:13:18 PM","dateUpdated":"Oct 29, 2026, 2:24:08 AM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
