CVE-2025-63878 identifies a SQL injection vulnerability in the Contact Form page of the Github Restaurant Website Restoran v1.0. SQL injection occurs when untrusted input is improperly sanitized and directly included in SQL queries, allowing attackers to manipulate the database commands executed by the application. In this case, the Contact Form likely accepts user input that is concatenated into SQL statements without adequate validation or parameterization. Exploiting this vulnerability could enable attackers to extract sensitive data such as customer information, modify or delete records, or escalate privileges within the database. Although no CVSS score or patches have been published yet, the vulnerability was reserved on October 27, 2025, and published on November 19, 2025. No known exploits have been reported, but the lack of mitigation increases risk. The affected software appears to be a niche restaurant website solution hosted on Github, which may be used by small to medium enterprises. The absence of detailed affected versions and patch links suggests that the vulnerability is newly discovered and remediation guidance is pending. SQL injection remains one of the most critical web application vulnerabilities due to its potential for severe impact and relative ease of exploitation, especially if the vulnerable input is exposed publicly without authentication or user interaction requirements.

For European organizations, this vulnerability poses a significant risk to the confidentiality, integrity, and availability of their web applications and underlying databases. Restaurants and hospitality businesses using the affected website or similar platforms could suffer data breaches exposing customer personal data, payment details, or internal business information. Data manipulation could lead to fraudulent transactions or loss of trust. Additionally, attackers might leverage the vulnerability to disrupt services, causing downtime and reputational damage. Given the hospitality sector's importance in Europe, especially in countries with large tourism industries, the impact could extend to economic losses and regulatory penalties under GDPR for data protection failures. The lack of known exploits currently limits immediate widespread impact, but the vulnerability's presence in publicly accessible contact forms increases exposure. Organizations relying on third-party or open-source web solutions must be vigilant to prevent exploitation and ensure compliance with data security standards.

To mitigate CVE-2025-63878, organizations should immediately audit the Contact Form implementation and any other user input handling components for SQL injection risks. Specific steps include: 1) Implementing parameterized queries or prepared statements to separate code from data; 2) Applying strict input validation and sanitization, restricting input length and allowed characters; 3) Employing web application firewalls (WAFs) configured to detect and block SQL injection attempts; 4) Conducting thorough code reviews and penetration testing focused on injection vulnerabilities; 5) Monitoring logs for suspicious database query patterns; 6) Updating or patching the affected software as soon as vendor fixes become available; 7) Considering migration to more secure web frameworks or CMS platforms if the current solution lacks active maintenance; 8) Training developers on secure coding practices to prevent similar vulnerabilities. Additionally, organizations should ensure compliance with GDPR by protecting customer data and reporting breaches promptly if exploitation occurs.
