CVE-2026-5551 describes a SQL Injection vulnerability discovered in itsourcecode Free Hotel Reservation System, versions 1.0.0 through 1.0. This flaw allows attackers to inject malicious SQL code through the manipulation of the 'email' parameter in the /hotel/admin/login.php file. Successful exploitation could lead to unauthorized access to sensitive data and compromise the integrity of the system. A public proof-of-concept is available, indicating a heightened risk.
The SQL Injection vulnerability in itsourcecode Free Hotel Reservation System allows an attacker to directly interact with the database underlying the application. By crafting malicious SQL queries, an attacker could bypass authentication mechanisms, potentially gaining administrative access. This could lead to the exfiltration of sensitive customer data, including reservation details, personal information, and payment card data. Furthermore, the attacker could modify or delete data, disrupting the hotel's operations and causing significant financial and reputational damage. The availability of a public exploit significantly increases the likelihood of exploitation.
CVE-2026-5551 is a publicly disclosed vulnerability with a readily available proof-of-concept. This significantly increases the risk of exploitation. The vulnerability is not currently listed on CISA KEV, but the presence of a public exploit warrants immediate attention. Given the ease of exploitation, attackers are likely to actively target vulnerable systems.
