CVE-2025-10740 is a SQL Injection vulnerability classified under CWE-89 found in the rupok98 URL Shortener Plugin for WordPress. The vulnerability stems from improper neutralization of special elements in SQL commands due to a missing capability check in the verifyRequest function. This function is part of the plugin's API and is responsible for verifying requests to modify shortened URLs. Because the plugin fails to verify user capabilities properly, any authenticated user with Subscriber-level access or above can exploit this flaw to inject malicious SQL commands. This can lead to unauthorized modification of URL links managed by the plugin, potentially altering redirect targets or injecting malicious payloads. The vulnerability is remotely exploitable without user interaction, with a CVSS 3.1 base score of 6.3, indicating medium severity. The attack vector is network-based, requiring low attack complexity and privileges of a low-level authenticated user. The scope is unchanged, meaning the impact is limited to the vulnerable plugin's data and functionality. Although no known exploits are currently reported, the vulnerability poses a risk to WordPress sites using this plugin, especially those with multiple users having Subscriber or higher roles. The lack of a patch at the time of publication necessitates immediate mitigation steps to prevent exploitation.

For European organizations, this vulnerability could lead to unauthorized modification of URL redirections, potentially redirecting users to malicious sites, facilitating phishing, malware distribution, or data exfiltration. The integrity of web content and user trust can be compromised, impacting brand reputation and user safety. Confidentiality may be affected if attackers leverage the injection to extract sensitive data from the underlying database. Availability could also be impacted if attackers disrupt URL shortening services, causing denial of service for legitimate users. Organizations relying on the plugin for marketing, internal communications, or customer engagement may face operational disruptions. Given the widespread use of WordPress across Europe, especially in SMEs and public sector websites, the vulnerability presents a tangible risk. Attackers with low privileges can exploit this, increasing the threat surface. The absence of known exploits suggests a window for proactive defense, but also a risk of future exploitation once public awareness grows.

1. Immediately restrict access to the URL Shortener Plugin's API endpoints to trusted administrators only, using web application firewalls or access control lists. 2. Implement strict role-based access controls within WordPress to limit Subscriber-level users from accessing or modifying plugin functionality. 3. Monitor plugin usage logs for unusual modification attempts or SQL error messages indicative of injection attempts. 4. Disable or uninstall the rupok98 URL Shortener Plugin if it is not essential to reduce attack surface. 5. Stay alert for official patches or updates from the vendor and apply them promptly once released. 6. Employ input validation and sanitization at the application level as an additional safeguard. 7. Conduct security audits and penetration testing focusing on WordPress plugins to detect similar vulnerabilities. 8. Educate users with Subscriber-level access about the risks and encourage minimal privilege principles. 9. Use security plugins that can detect and block SQL injection attempts in real-time. 10. Regularly back up WordPress site data to enable quick recovery in case of compromise.
