EUVD Vulnerability Catalog
EUVD-2026-67132
Severity: CRITICAL
Base Score: 9.1
CVSS Version: 4.0
Vulnerability Description
Affected versions of Flowintel do not revoke existing authenticated sessions when a user’s password is changed.
This means that if an attacker already possesses a valid session—for example, from prior access or a stolen session token—the victim changing their password does not terminate that attacker’s access. The session remains usable until it expires naturally. The upstream commit describes this directly as:
“session keeps working until it expires.”
The fix detects password changes and explicitly invokes _invalidate_user_sessions(user.id) after the database update. This is applied in both edit_user_core() and admin_edit_user_core().
