Budibase: OIDC SSO account takeover: incoming identity linked by email without checking email_verified
Impact
Budibase is an open-source low-code platform. Prior to 3.39.30, the OIDC flow in packages/backend-core/src/middleware/passport/sso/oidc.ts resolved an email without getEmailVerified or an email_verified requirement, and packages/backend-core/src/middleware/passport/sso/sso.ts then used users.getGlobalUserByEmail as a fallback account-linking key. An attacker who can authenticate through a configured identity provider that asserts a victim email as unverified can have a fresh provider identity merged into the victim Budibase account and inherit the victim roles. This issue is fixed in version 3.39.30.
