CVE-2025-63878 identifies a SQL injection vulnerability in the Contact Form page of the Github Restaurant Website Restoran v1.0. SQL injection (CWE-89) occurs when user-supplied input is improperly sanitized before being included in SQL queries, allowing attackers to manipulate backend database queries. In this case, the Contact Form fails to properly validate or parameterize inputs, enabling remote attackers to inject malicious SQL code without requiring authentication or user interaction. The CVSS 3.1 score of 6.5 reflects a medium severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). The impact affects confidentiality and integrity (C:L/I:L) but not availability (A:N), meaning attackers could potentially read or modify sensitive data but not disrupt service. No patches or known exploits are currently available, indicating the vulnerability is newly disclosed. The vulnerability's presence in a restaurant website suggests potential exposure of customer data, reservation details, or internal business information if exploited. The lack of authentication requirement increases the risk, as attackers can target the site remotely without credentials. The vulnerability is typical of web applications that do not implement secure coding practices such as prepared statements or input sanitization. Organizations using this software or similar vulnerable versions should prioritize remediation to prevent data breaches or unauthorized data manipulation.

For European organizations, especially small and medium-sized enterprises (SMEs) in the hospitality sector using the Github Restaurant Website Restoran v1.0 or similar vulnerable platforms, this vulnerability poses a risk of unauthorized data access and modification. Attackers exploiting the SQL injection could extract sensitive customer information, including contact details and reservation data, potentially leading to privacy violations under GDPR. Integrity compromise could allow attackers to alter reservation records or business data, disrupting operations and damaging reputation. Although availability is not directly impacted, the breach of confidentiality and integrity could result in regulatory penalties and loss of customer trust. The vulnerability's remote exploitation capability without authentication increases the attack surface, making it attractive for opportunistic attackers. European organizations with limited cybersecurity resources may be particularly vulnerable if they have not implemented secure coding or web application firewall protections. The absence of known exploits currently reduces immediate risk but also means organizations should act proactively before exploitation occurs. The impact is more pronounced in countries with a high density of hospitality businesses relying on such web platforms.

To mitigate CVE-2025-63878, organizations should immediately review and update the Contact Form implementation to use parameterized queries or prepared statements, eliminating direct concatenation of user input into SQL commands. Input validation should be enforced both client-side and server-side to reject malicious payloads. Employing a web application firewall (WAF) with SQL injection detection rules can provide an additional layer of defense by blocking suspicious requests. Regular security code reviews and penetration testing should be conducted to identify and remediate similar vulnerabilities. Organizations should monitor web server logs for unusual query patterns indicative of injection attempts. If possible, isolate the vulnerable application from critical backend systems to limit potential damage. Applying the principle of least privilege to database accounts used by the web application can reduce the impact of a successful injection. Finally, organizations should stay informed about official patches or updates from the software maintainers and apply them promptly once available.
