description

ToolJet onboarding signup handling is affected through 3.20.256-lts and 3.21.93-beta. A remote attacker may bypass authentication checks during user activation if they can submit a crafted email value to the exposed signup endpoint.

mitigation

Upgrade ToolJet to 3.21.94-beta or a later release that includes the fix. Until upgraded, restrict network access to the onboarding signup endpoint to trusted users and networks.
