CVE-2026-68551

Budget Board's OIDC login links to an existing local account by email alone, with no email_verified check, enabling account takeover of pre-existing users

Published Nov 13, 2026 CVSS 4.0 · 8.3 High EPSS n/a KEV · Not listed
Description
Budget Board is an app for tracking monthly spending and working towards financial goals. Prior to version 3.6.2, Budget Board's OIDC login flow finds and signs into an existing local account purely by matching the email address asserted in the identity provider's token - it never checks the standard email_verified claim. If the configured OIDC provider ever allows a user to register or display an email address without proving they own it , an attacker can register there using a victim's email and get signed into the victim's existing Budget Board account - including all their linked bank data. This issue has been patched in version 3.6.2.
