CVE-2025-48299 is a high-severity SQL Injection vulnerability (CWE-89) found in the YayCommerce YayExtra plugin, affecting versions up to 1.5.5. SQL Injection occurs when user-supplied input is improperly neutralized before being included in SQL commands, allowing an attacker to manipulate the backend database queries. This vulnerability enables a remote attacker with high privileges (authentication required) to inject malicious SQL code due to insufficient input sanitization or parameterization. The CVSS 3.1 score of 7.6 reflects a network attack vector with low attack complexity but requiring privileges, no user interaction, and a scope change, indicating that the vulnerability can affect components beyond the initially vulnerable module. The impact primarily compromises confidentiality by allowing unauthorized reading of sensitive data, with limited impact on availability (low impact) and no direct integrity modification. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability was reserved in May 2025 and published in July 2025, indicating recent discovery. YayExtra is an e-commerce extension, likely used to enhance online store functionality, and the SQL Injection could allow attackers to extract sensitive customer or transactional data from the underlying database, posing significant risks to data privacy and compliance.

For European organizations using YayCommerce YayExtra, this vulnerability poses a significant risk to the confidentiality of customer and business data stored in e-commerce databases. Exploitation could lead to unauthorized data disclosure, including personal data protected under GDPR, resulting in legal and financial repercussions. The scope change in the CVSS vector suggests that the vulnerability could affect other components or modules, potentially broadening the attack surface. Although exploitation requires authenticated access, insider threats or compromised credentials could facilitate attacks. The limited impact on availability reduces the risk of service disruption, but data breaches could damage brand reputation and customer trust. Given the e-commerce context, financial fraud or theft of payment information is also a concern. European organizations must consider the regulatory implications of data breaches and the potential for targeted attacks against online retail platforms, especially during high-traffic periods.

1. Immediate mitigation should include restricting access to the vulnerable YayExtra plugin functionalities to trusted and minimal user roles to reduce the risk of exploitation by authenticated attackers. 2. Implement strict input validation and parameterized queries in the plugin code to neutralize SQL special characters and prevent injection. 3. Monitor database query logs for unusual or anomalous queries that could indicate attempted exploitation. 4. Conduct a thorough security audit of the YayExtra plugin and related e-commerce components to identify and remediate similar injection points. 5. Apply network segmentation and database access controls to limit the impact of a successful injection attack. 6. Prepare incident response plans specifically for e-commerce data breaches, including GDPR notification procedures. 7. Stay alert for official patches or updates from YayCommerce and apply them promptly once available. 8. Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting YayExtra endpoints. 9. Educate administrators and developers on secure coding practices and the risks of SQL injection in e-commerce environments.
