Description
The vulnerability allows any authenticated user to change their own password without providing the current password or having an active elevated session. It also allows the attacker to change other users’ passwords if the attacker’s account has edit users permission (which doesn’t allow changing others’ passwords) and lacks Administrate users permission (which is required to change others’ passwords).
The vulnerability exists in the elements/save action when saving a User element. The UserPasswordValidator applies only a safe validator to the newPassword field without an on scenario restriction. This makes newPassword mass-assignable during the generic element save flow, completely bypassing the dedicated users/set-password action that enforces elevated session verification.
An attacker with any authenticated session (whether it’s hijacked or a normal / low-privileged user) can change their own password, and potentially take over administrator accounts.
Required Permissions
- Access the control panel
- Edit users (needed for the account takeover attack scenario)
Impact
- Any authenticated user can change their own password without providing their current password.
- Users with Edit users permission can change any user’s password, including administrators.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for craftcms/cms, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update craftcms/cms to 5.10.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-72786 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
