CVE-2026-12375 in uncanny-automator-pro Plugin
Summary
by MITRE • 07/07/2026
The uncanny-automator-pro WordPress plugin before 7.3.0.6 was distributed with malicious code after the vendor's uncanny-automator-pro WordPress plugin before 7.3.0.6 update/distribution infrastructure was compromised; the injected backdoor grants unauthenticated attackers an administrator session on affected sites and beacons the site's secret keys and administrator details to attacker-controlled servers.

The compromised uncanny automator pro wordpress plugin represents a sophisticated supply chain attack that exploited the update infrastructure of a legitimate software vendor. This vulnerability demonstrates how attackers can leverage trusted distribution channels to infiltrate wordpress ecosystems, targeting the core infrastructure that maintains plugin integrity. The malicious code injection occurred during the software update process rather than through direct exploitation of the plugin's functionality, making it particularly dangerous as users would typically trust updates from official sources. Such attacks exploit the fundamental trust model within wordpress plugin ecosystems where administrators expect downloaded updates to be secure and authentic.
The technical flaw in this vulnerability lies in the compromised update infrastructure that allowed attackers to inject backdoor code into the plugin distribution system. The malicious code specifically targets the authentication mechanisms within the plugin, enabling unauthenticated attackers to escalate privileges and obtain administrator sessions without requiring valid credentials. This represents a critical privilege escalation vulnerability that bypasses standard wordpress security controls. The backdoor functionality includes automated beaconing capabilities that exfiltrate sensitive information including site secret keys and administrator details to attacker-controlled servers, effectively providing persistent access and data theft capabilities.
The operational impact of this vulnerability extends far beyond individual plugin compromise, as it affects the entire wordpress ecosystem relying on the compromised vendor infrastructure. Administrators who installed or updated the plugin would unknowingly have granted attackers full administrative control over their websites, potentially compromising multiple sites within a network. The beaconing mechanism creates persistent communication channels between compromised sites and attacker infrastructure, enabling ongoing surveillance and data exfiltration without immediate detection. This type of attack can remain undetected for extended periods, allowing attackers to establish long-term presence and expand their access across interconnected systems.
Security professionals should immediately implement comprehensive mitigation strategies including verification of plugin integrity through cryptographic checksums, monitoring for unusual network traffic patterns, and deployment of network intrusion detection systems. The compromised update infrastructure highlights the importance of using multiple verification methods beyond simple signature validation and implementing robust security monitoring for all automated update processes. Organizations must also consider immediate plugin removal from affected systems and establishment of secure update procedures that verify software integrity through multiple independent channels. This vulnerability underscores the necessity of maintaining updated security practices and the critical importance of supply chain security in modern software ecosystems, where traditional perimeter-based defenses prove insufficient against sophisticated supply chain attacks.
