This results in a classic reflected cross\u2011site scripting vulnerability described by CWE\u201179, and the presence of dynamic code execution features indicates potential indirect code injection as CWE\u201194.

The EPSS score is reported below 1\u202f%, suggesting a very low probability of exploitation at the time of publication, and the vulnerability is not included in CISA\u2019s KEV catalog. Exploitation requires a remote attacker to lure a victim\u2019s browser to the vulnerable endpoint and supply crafted input; the impact is confined to the browser session and does not provide native code execution or system compromise. Despite the moderate score, the potential for user\u2011session compromise warrants timely remediation."}}}}, "created": "2026-03-09T10:02:49.287736+00:00", "updated": "2026-04-16T10:30:16.180230+00:00", "vendors": ["code-projects", "code-projects$PRODUCT$simple_flight_ticket_booking_system"]}
