A vulnerability was found in OpenCart 4.1.0.3/4.1.0.4. The impacted element is an unknown function of the file catalog/controller/account/address.php of the component Autocomplete Workflow. The manipulation of the argument address_1 results in cross site scripting. It is possible to launch the attack remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Stored cross-site scripting in OpenCart 4.1.0.3 and 4.1.0.4 allows an authenticated low-privilege user (e.g., a customer account) to inject malicious script into the address_1 field via the Autocomplete Workflow in catalog/controller/account/address.php, which then executes in the browser of any user who subsequently views the stored address data. A public proof-of-concept exploit is available on GitHub. …

Vulnerability AssessmentAI
| Exploitation | The attacker must hold a low-privilege authenticated account on the OpenCart store - a customer account obtained via self-registration (the default configuration for most OpenCart storefronts) is sufficient. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 5.1 (Medium) with vector AV:N/AC:L/AT:N/PR:L/UI:P/E:P accurately captures the moderate severity: network-reachable, low complexity, but requires authenticated access and passive victim interaction. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch has been identified at time of analysis - the OpenCart vendor did not respond to the disclosure report. … Detailed patch versions, workarounds, and compensating controls in full report. |
