The vulnerability identified as CVE-2025-9542 affects the AutomatorWP plugin for WordPress, a tool designed to enable no-code automations, webhooks, and custom integrations. The root cause is a missing authorization check (CWE-862) in multiple plugin functions, which fails to verify whether the authenticated user has sufficient privileges before allowing access to sensitive operations. Specifically, users with Subscriber-level access or higher can exploit this flaw to view and modify integration settings and existing automation workflows without proper authorization. This vulnerability affects all versions up to and including 5.3.7 of the plugin. The CVSS 3.1 base score is 5.4, reflecting a medium severity with network attack vector, low attack complexity, and requiring low privileges but no user interaction. The impact primarily concerns confidentiality and integrity of the plugin's configuration data, as attackers can alter automation rules or extract sensitive integration details. No availability impact is noted. The vulnerability is exploitable remotely over the network, increasing its risk profile. No public exploits have been reported yet, but the widespread use of WordPress and the plugin's role in automations make this a notable threat. The absence of patch links suggests that fixes may be pending or not yet publicly released. The vulnerability was reserved and published in late August and early September 2025, respectively, by Wordfence.

This vulnerability allows attackers with minimal privileges (Subscriber-level) to escalate their effective permissions within the AutomatorWP plugin context, potentially leading to unauthorized disclosure and modification of automation workflows. Such unauthorized changes can disrupt business processes automated via the plugin, possibly causing operational issues, data leakage, or unintended actions triggered by compromised automations. While the vulnerability does not directly impact the entire WordPress site or server availability, the integrity and confidentiality of automation configurations are at risk. Attackers could leverage this to gain insights into integration endpoints or manipulate workflows to facilitate further attacks or data exfiltration. Organizations relying heavily on automated workflows for critical business functions may experience degraded service quality or security breaches. The medium CVSS score reflects the moderate but tangible risk posed by this vulnerability, especially in environments with multiple users having Subscriber or higher roles.

1. Immediately restrict user roles and permissions to the minimum necessary, especially limiting Subscriber-level users from accessing sensitive plugin features until a patch is available. 2. Monitor and audit user activities related to the AutomatorWP plugin to detect unauthorized changes or access attempts. 3. Apply principle of least privilege across WordPress user roles to reduce the attack surface. 4. Stay informed about official patches or updates from the plugin vendor and apply them promptly once released. 5. If possible, temporarily disable the AutomatorWP plugin or its automation features until a fix is deployed in high-risk environments. 6. Implement web application firewall (WAF) rules to detect and block suspicious requests targeting the plugin’s endpoints. 7. Conduct regular backups of WordPress site data and plugin configurations to enable quick restoration if unauthorized modifications occur. 8. Educate site administrators and users about the risks of privilege escalation and encourage strong password policies to prevent account compromise.
