Impact
A stored cross‑site scripting vulnerability exists in the User Registration module of code‑projects Simple Inventory System 1.0. An attacker can submit a malicious value for the last_name field on /register.php; the payload is stored and later rendered without proper escaping, allowing arbitrary JavaScript to execute in the browsers of users who view the stored value.
Affected Systems
The flaw is present only in version 1.0 of code‑projects Simple Inventory System, specifically in the register.php endpoint of the User Registration component. No other versions or components are known to be affected.
Risk and Exploitability
The CVSS base score is 5.3, indicating moderate severity. EPSS data is not available and the vulnerability is not listed in the CISA KEV catalog. The register.php endpoint is publicly reachable, so remote exploitation is possible. The description does not state that authentication or elevated privileges are required; based on that statement it is inferred that a user can supply the payload without logging in.
