CVE-2025-62006 identifies a Missing Authorization vulnerability in the VeronaLabs WP SMS plugin for WordPress, affecting all versions up to and including 7.0.1. Missing authorization means that certain sensitive functions or endpoints within the plugin do not properly verify whether the user has the necessary permissions before allowing access or execution. This can enable unauthenticated or low-privileged attackers to invoke privileged actions such as sending SMS messages, modifying plugin settings, or accessing sensitive data managed by the plugin. The WP SMS plugin is widely used to integrate SMS functionality into WordPress sites, often for notifications, two-factor authentication, or marketing communications. The lack of authorization checks undermines the integrity and confidentiality of these communications and can lead to abuse such as spam SMS sending, phishing, or unauthorized information disclosure. Although no public exploits have been reported yet, the vulnerability is critical because it does not require authentication or user interaction, making exploitation relatively straightforward once discovered. The absence of a CVSS score complicates risk quantification, but the potential impact on confidentiality, integrity, and availability of SMS services is significant. VeronaLabs has not yet released a patch or mitigation guidance, so affected users must take interim protective measures. This vulnerability highlights the importance of strict access control enforcement in plugins that handle communication channels.

For European organizations, exploitation of this vulnerability could lead to unauthorized SMS transmissions, potentially resulting in reputational damage, financial fraud, or regulatory non-compliance, especially under GDPR where unauthorized data processing is a concern. Organizations relying on WP SMS for critical alerts or multi-factor authentication risk losing control over communication channels, which could facilitate phishing or social engineering attacks. The integrity of SMS-based notifications could be compromised, leading to misinformation or disruption of business processes. Additionally, unauthorized SMS sending could incur unexpected costs or trigger spam blacklisting, affecting broader communication capabilities. Sectors such as finance, healthcare, and government, which often use SMS for sensitive notifications, are particularly vulnerable. The lack of authentication requirement increases the attack surface, making it easier for attackers to exploit the vulnerability remotely. The overall impact includes potential confidentiality breaches, integrity violations, and service disruption, which can have cascading effects on organizational security posture and compliance obligations.

1. Immediately audit all WP SMS plugin installations to identify affected versions (<=7.0.1). 2. Restrict access to WordPress administrative and plugin endpoints using web application firewalls (WAFs) or IP whitelisting to limit exposure. 3. Disable or uninstall the WP SMS plugin if SMS functionality is not critical or can be temporarily suspended. 4. Monitor outgoing SMS traffic for unusual patterns or spikes that may indicate exploitation. 5. Implement strict role-based access controls within WordPress to minimize permissions for users interacting with the plugin. 6. Follow VeronaLabs announcements closely for patches or security updates and apply them promptly once available. 7. Consider alternative SMS plugins with verified security postures if immediate patching is not possible. 8. Educate staff about potential phishing or social engineering risks stemming from unauthorized SMS messages. 9. Conduct penetration testing focused on plugin authorization controls to detect similar weaknesses. 10. Maintain comprehensive logging and alerting on plugin-related activities to facilitate rapid incident response.
