CVE-2026-25043 Budibase CVE debrief

CVE-2026-25043 is a business logic vulnerability in Budibase’s password reset functionality prior to version 3.23.25. The vulnerability allows an unauthenticated attacker to repeatedly trigger password reset requests for the same email address, resulting in hundreds of password reset emails being sent in a short time window. This enables large-scale email flooding, user harassment, denial of service (DoS) against user inboxes, and potential financial and reputational impact for Budibase. Budibase users and administrators should be aware of this vulnerability and take steps to mitigate it.

Recommended defensive actions

  • Update Budibase to version 3.23.25 or later
  • Implement rate limiting and CAPTCHA on the 'Forgot Password' endpoint
  • Monitor for potential email flooding and harassment attacks
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
