Stored cross-site scripting in SourceCodester Inventory System 1.0 allows remote unauthenticated attackers to inject persistent malicious scripts via the fullname and username parameters in /users.php on the User Management Page. When an authenticated user - likely an administrator - visits the affected page, the injected script executes in their browser session, enabling session hijacking, credential theft, or unauthorized UI manipulation. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must be able to reach the /users.php endpoint over the network (AV:N) - the application is PHP/MySQL-based and typically HTTP-exposed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 4.3 (Medium) reflects the low integrity-only impact (I:L) and required user interaction (UI:R), which mechanically suppresses the score. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated external attacker submits a crafted HTTP POST request to /users.php with a fullname or username value containing a JavaScript payload (e.g., a session cookie-stealing script). The payload is stored in the application database without sanitization. … |
| Remediation | No vendor-released patch has been identified at time of analysis - the CVSS RL:X modifier and absence of any advisory from SourceCodester confirm this. … Detailed patch versions, workarounds, and compensating controls in full report. |
