A vulnerability has been found in SourceCodester Inventory Management System 1.0. Affected is an unknown function of the file /api/customers_handler.php of the component Customer Management Module. Such manipulation of the argument Customer_Name leads to cross site scripting. The attack can be executed remotely. The exploit has been disclosed to the public and may be used.
AnalysisAI
Reflected or stored cross-site scripting in SourceCodester Inventory Management System 1.0 allows an authenticated remote attacker to inject malicious JavaScript via the Customer_Name parameter in the Customer Management Module's /api/customers_handler.php endpoint. When a second user (such as an administrator) loads the affected customer record, the payload executes in their browser, enabling session hijacking or unauthorized actions on their behalf. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires: (1) a valid account in the Inventory Management System with at least low-privilege access sufficient to create or modify customer records (PR:L per CVSS 4.0); (2) a second user - typically an administrator - who passively loads the page that renders the injected Customer_Name value (UI:P per CVSS 4.0). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 5.1 (Medium) accurately reflects a constrained threat: the attacker must hold a valid low-privilege account (PR:L) and a second user must load the injected content (UI:P), which together substantially limit opportunistic mass exploitation. … 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; SourceCodester projects are typically not accompanied by formal security advisories or patch releases. … Detailed patch versions, workarounds, and compensating controls in full report. |
