Name of the Vulnerable Software and Affected Versions
Budibase versions prior to 3.39.30
Description
The OIDC flow in
packages/backend-core/src/middleware/passport/sso/oidc.ts resolves an email without requiring getEmailVerified or email verified. Subsequently, packages/backend-core/src/middleware/passport/sso/sso.ts uses the users.getGlobalUserByEmail() function as a fallback account-linking key. This allows an attacker to authenticate via a configured identity provider that asserts an unverified email belonging to a victim, enabling the attacker to merge a new provider identity into the victim's account and inherit their roles.Recommendations
Update to version 3.39.30.
