| Title | opencart 4.1.0.3 Cross Site Scripting |
|---|
| Description | OpenCart x.x.x.x contains a stored cross-site scripting vulnerability in the admin order and return workflows. A normal front-office customer can store attacker-controlled HTML in profile fields such as firstname. When an administrator later uses the backend customer autocomplete workflow and selects the attacker-controlled customer, the stored value is decoded and injected into backend HTML without safe encoding, leading to JavaScript execution in the administrator browser. Administrator privileges are not required for the attacker; a normal customer account is sufficient. |
