AI-Generated

Budibase versions prior to 3.39.30 are vulnerable due to a flaw in the OIDC flow that allows an attacker to authenticate using an unverified email, potentially merging their identity with a victim's account and inheriting their roles. This critical vulnerability poses a significant risk to user account integrity and access control. Organizations using Budibase should prioritize updating to version 3.39.30 to mitigate the risk of unauthorized account access.

Original NVD Description

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.
