Databasement Invitation Token Validation Bypass Leading to Account Takeover

Executive Summary

This vulnerability in Databasement before 1.7.14 allows attackers to bypass authorization by exploiting stale invitation tokens. The application caches authorization decisions when the acceptance page loads but does not re-validate tokens during the actual acceptance process. Attackers with a leaked or forwarded invitation link can load the page while the token is pending, then accept it after the legitimate user has already done so. This lets them overwrite the account password and gain access to managed database credentials and secrets.

Detection Guidance

Check if your Databasement instance is running a version before 1.7.14. Review logs for unusual invitation acceptance events where tokens were used after the legitimate user had already accepted. Inspect network traffic for repeated requests to the invitation acceptance endpoint.
