CVE-2025-66056 is a vulnerability identified in the Uncanny Owl Uncanny Automator plugin, affecting all versions prior to 6.10.0. The flaw allows an authenticated user with limited privileges to remotely retrieve embedded sensitive system information that should otherwise be inaccessible. This exposure occurs due to insufficient access control or improper data handling within the plugin's automation workflows or data retrieval mechanisms. The vulnerability does not require user interaction and can be exploited over the network, making it a remote attack vector. The CVSS v3.1 score is 4.3 (medium), reflecting low attack complexity and no user interaction but requiring privileges. The impact is limited to confidentiality, with no direct effect on integrity or availability. No public exploits have been reported, indicating the threat is currently theoretical but should be addressed proactively. The vulnerability could be leveraged by attackers to gather information useful for further attacks such as privilege escalation or lateral movement within compromised WordPress environments. Uncanny Automator is a popular WordPress plugin used to automate workflows, so the exposure of sensitive data could affect websites relying on it for business-critical automation tasks.

For European organizations, the exposure of sensitive system information can lead to increased risk of targeted attacks, including privilege escalation and data breaches. Organizations using Uncanny Automator in their WordPress infrastructure may inadvertently expose configuration details, credentials, or other embedded secrets that facilitate further compromise. This is particularly concerning for sectors with stringent data protection requirements such as finance, healthcare, and government. The vulnerability's medium severity means it is not immediately critical but should be addressed promptly to prevent attackers from gaining reconnaissance advantages. The impact on confidentiality could lead to regulatory non-compliance under GDPR if personal or sensitive data is indirectly exposed. Additionally, disruption of automated workflows due to exploitation attempts could affect business operations.

The primary mitigation is to update Uncanny Automator to version 6.10.0 or later, where the vulnerability is patched. Until the update is applied, organizations should restrict access to the plugin’s administrative and automation configuration interfaces to trusted and authenticated users only, minimizing the attack surface. Employing the principle of least privilege for WordPress user roles can reduce the risk of exploitation. Monitoring logs for unusual access patterns related to the plugin’s endpoints can help detect attempted exploitation. Additionally, implementing web application firewalls (WAF) with custom rules to block suspicious requests targeting Uncanny Automator may provide temporary protection. Regular security audits of WordPress plugins and dependencies should be conducted to identify and remediate similar issues proactively.
