CVE-2026-3763 describes a cross-site scripting (XSS) vulnerability discovered in the Simple Flight Ticket Booking System, version 1.0. This flaw allows attackers to inject malicious scripts into the application, potentially compromising user sessions and stealing sensitive data. The vulnerability resides within an unknown function of the showhistory.php file and can be exploited remotely. A public proof-of-concept exists, increasing the risk of exploitation.
Successful exploitation of CVE-2026-3763 enables an attacker to execute arbitrary JavaScript code within the context of a user's browser session. This can lead to various malicious outcomes, including session hijacking, phishing attacks, and defacement of the application. An attacker could steal user credentials, redirect users to malicious websites, or inject malware. The impact is amplified if the application handles sensitive data, such as flight booking information or payment details. Given the public availability of a proof-of-concept, the risk of exploitation is considered high.
CVE-2026-3763 has been publicly disclosed and a proof-of-concept is available, indicating a high probability of exploitation. The vulnerability is not currently listed on CISA KEV. The public availability of the exploit suggests that attackers are actively seeking to exploit this vulnerability. The NVD publication date is 2026-03-08.
Organizations utilizing the Simple Flight Ticket Booking System version 1.0, particularly those handling sensitive user data or integrated with other critical systems, are at significant risk. Shared hosting environments where multiple applications share the same server resources are also vulnerable, as an attack on one application could potentially compromise others.
