The application accepts a 'limit' query parameter without sanitizing it, so a crafted URL can inject arbitrary JavaScript or HTML. A remote attacker can trigger the execution of the injected script in the victim's browser. The impact of this flaw is that an attacker can perform actions such as stealing session cookies, defacing the site, or injecting malware, thereby compromising the confidentiality and integrity of user data. The weakness is an instance of CWE\u201179: Improper Neutralization of Input During Web Page Generation.", "risk_and_exploitability": "The CVSS score of 4.8 indicates moderate severity, while an EPSS score of <1% shows that current exploit prevalence is very low. The flaw is not listed in the CISA KEV catalog. Attackers would need to entice a user to visit a malicious URL containing a malicious 'limit' parameter; no authentication or privileged access is required. Exploitation is straightforward for someone with knowledge of XSS techniques, but environmental constraints such as additional input filtering could mitigate risk."}}}}, "created": "2026-03-27T20:25:50.975916+00:00", "title": "Reflected XSS via limit Parameter in SourceCodester Sales and Inventory System", "updated": "2026-03-30T20:57:07.141590+00:00", "vendors": ["sourcecodester", "sourcecodester$PRODUCT$inventory_system"]}
