ROUNDCUBE WEBMAIL FLAW NOW UNDER ACTIVE ATTACK

Roundcube Webmail users face immediate risk from a high-severity flaw that allows code injection attacks. Despite a patch released in May, threat actors are now actively leveraging the vulnerability to compromise systems. The Canadian Centre for Cyber Security flagged the active exploitation, urging organizations to prioritize updates. Roundcube, a widely-used open-source webmail client, powers email access for numerous businesses and service providers. Code injection vulnerabilities enable attackers to insert malicious code into applications, potentially granting them unauthorized access or control over affected systems. The flaw's active exploitation underscores the risk of delayed patching. Administrators should apply the May patch immediately if not already done. Organizations using Roundcube should verify their systems are running the latest version and monitor for suspicious activity. The vulnerability represents a critical risk to email infrastructure security.
