CVE-2025-13077 is a time-based blind SQL Injection vulnerability identified in the payamito sms woocommerce plugin for WordPress, which is widely used to integrate SMS functionality with WooCommerce stores. The vulnerability arises from improper neutralization of special elements in SQL commands (CWE-89) specifically via the 'columns' parameter. The plugin fails to sufficiently escape or prepare user-supplied input before incorporating it into SQL queries, allowing unauthenticated attackers to inject arbitrary SQL code. This injection can be exploited to append additional SQL queries, enabling attackers to infer sensitive information from the backend database through time delays in query execution. The vulnerability affects all versions up to and including 1.3.5. The CVSS 3.1 base score is 7.5, reflecting network attack vector, low attack complexity, no privileges or user interaction required, and a high impact on confidentiality, though integrity and availability remain unaffected. No patches or known exploits have been reported yet, but the vulnerability's nature makes it a significant risk for data leakage. The plugin's integration with WooCommerce means that compromised data could include customer details, order information, and potentially payment data, depending on the backend database schema. This vulnerability is particularly concerning for e-commerce sites relying on this plugin for SMS notifications or marketing, as attackers could silently extract data without detection.

For European organizations, the impact of CVE-2025-13077 could be substantial, especially for e-commerce businesses using WooCommerce with the vulnerable payamito sms plugin. Successful exploitation could lead to unauthorized disclosure of sensitive customer data, including personal information and order details, potentially violating GDPR requirements and resulting in regulatory penalties. The breach of confidentiality could damage customer trust and brand reputation. Since the vulnerability does not affect integrity or availability, direct service disruption is unlikely, but the silent data exfiltration risk remains high. Organizations handling large volumes of transactions or sensitive communications via SMS are at increased risk. Additionally, attackers could leverage extracted data for further attacks such as phishing or fraud. The lack of authentication and user interaction requirements means attackers can exploit this remotely and anonymously, increasing the threat surface. European companies with limited security monitoring or outdated plugin versions are particularly vulnerable. The financial and legal consequences of data breaches in Europe heighten the importance of addressing this vulnerability promptly.

To mitigate CVE-2025-13077, organizations should immediately update the payamito sms woocommerce plugin to a version that addresses this vulnerability once available. In the absence of an official patch, temporary mitigations include implementing web application firewall (WAF) rules to detect and block suspicious SQL injection patterns targeting the 'columns' parameter. Input validation and sanitization should be enforced at the application level to reject unexpected or malformed input. Database queries should be refactored to use parameterized statements or prepared queries to prevent injection. Monitoring database logs for unusual query patterns or time delays can help detect exploitation attempts. Restricting direct database access and limiting the plugin's database permissions to the minimum necessary can reduce impact. Regular security audits and vulnerability scanning of WordPress plugins are recommended to identify and remediate similar issues proactively. Organizations should also review their incident response plans to address potential data breaches resulting from this vulnerability.
