CVE-2026-73303
CVE-2026-73303 · Budibase: Email Change IDOR via POST /api/v2/email allows full Account Takeover (accountId not validated against session)
This page contains facts from public vulnerability sources. Check the original advisory before updating.
Budibase is an open-source low-code platform. Prior to 3.40.0, POST /api/v2/email on account.budibase.app accepted a client-controlled accountId without binding it to the authenticated session, while checking only currentEmail. An authenticated attacker who obtains a victim account identifier can start the email-change workflow for the victim, receive and submit the verification code through POST /api/v2/email/verification, move the victim email to an attacker-controlled address, and complete a password reset as the victim. This issue is fixed in version 3.40.0.
