CVE-2025-10048 identifies a SQL Injection vulnerability in the My auctions allegro plugin for WordPress, affecting all versions up to and including 3.6.31. The root cause is insufficient escaping and lack of prepared statements for the 'order' parameter in SQL queries. This flaw allows authenticated attackers with Administrator-level privileges or higher to append malicious SQL code to existing queries. The vulnerability enables attackers to extract sensitive information from the database, compromising confidentiality. The CVSS 3.1 score is 4.9 (medium), reflecting network attack vector, low attack complexity, required high privileges, no user interaction, and impact limited to confidentiality. The vulnerability does not affect data integrity or availability. No public exploits have been reported yet, but the risk remains due to the potential for data leakage. The plugin is used in WordPress environments, commonly deployed in e-commerce and auction sites, making the vulnerability relevant to organizations relying on these platforms. The vulnerability was reserved in early September 2025 and published in October 2025, with no patches currently linked, indicating the need for immediate attention from site administrators.

The primary impact of CVE-2025-10048 is unauthorized disclosure of sensitive data stored in the WordPress site's database, such as user information, transaction details, or configuration data. Since the vulnerability requires Administrator-level access, the risk is somewhat mitigated by the need for high privileges; however, if an attacker compromises an admin account, they can leverage this flaw to escalate data exfiltration capabilities. The vulnerability does not allow modification or deletion of data, nor does it affect system availability, limiting the scope to confidentiality breaches. Organizations running the affected plugin on WordPress sites, especially those handling sensitive auction or e-commerce data, face increased risk of data leakage. This can lead to reputational damage, regulatory non-compliance, and potential financial losses. The absence of known exploits reduces immediate risk but does not eliminate the threat, as attackers may develop exploits in the future.

1. Immediately restrict Administrator-level access to trusted personnel only, minimizing the risk of insider threats or compromised accounts. 2. Implement strict input validation and sanitization for the 'order' parameter and any other user-supplied inputs in the plugin's code, ideally by applying prepared statements or parameterized queries to prevent SQL injection. 3. Monitor database query logs for unusual or unexpected queries that may indicate attempted exploitation. 4. Regularly audit user accounts and permissions to detect unauthorized privilege escalations. 5. If possible, disable or remove the My auctions allegro plugin until a vendor patch is released. 6. Stay informed on vendor updates or security advisories for the plugin and apply patches promptly once available. 7. Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the 'order' parameter. 8. Conduct security assessments and penetration testing focused on WordPress plugins to identify similar vulnerabilities proactively.
