Summary
by MITRE • 08/30/2023
The POEditor WordPress plugin before 0.9.8 does not have CSRF checks in various places, which could allow attackers to make logged in admins perform unwanted actions, such as reset the plugin's settings and update its API key via CSRF attacks.

The POEditor WordPress plugin vulnerability represents a critical security flaw that undermines the integrity of WordPress administrative sessions through cross-site request forgery attacks. This vulnerability affects versions prior to 098 and exposes administrators to unauthorized actions that can significantly compromise plugin functionality and potentially broader system security. The absence of proper CSRF protection mechanisms creates an exploitable vector where malicious actors can manipulate authenticated admin sessions without requiring explicit credentials.
The technical implementation flaw stems from the plugin's failure to validate the origin of requests made to its administrative endpoints. Specifically, the plugin lacks anti-CSRF tokens in its settings reset and API key update functionalities, which are critical administrative operations. This absence allows attackers to craft malicious requests that appear to originate from legitimate administrative sessions. The vulnerability manifests when administrators visit compromised websites or are tricked into clicking malicious links that automatically submit requests to the vulnerable plugin endpoints, leveraging the existing authentication state.
The operational impact of this vulnerability extends beyond simple configuration changes, as it enables attackers to modify critical plugin parameters that affect content management and translation workflows. When an administrator resets plugin settings, it can disrupt existing translation projects and potentially expose sensitive data. Updating API keys through CSRF attacks allows attackers to gain unauthorized access to translation services and potentially compromise translation workflows. This vulnerability particularly affects organizations that rely heavily on translation services and content management systems where plugin integrity is crucial for business operations.
Security professionals should note that this vulnerability aligns with CWE-352, which specifically addresses Cross-Site Request Forgery weaknesses in web applications. The issue also maps to ATT&CK technique T1078.004, which covers valid accounts used for unauthorized access, as the attack leverages legitimate administrative sessions. Organizations should implement immediate mitigations including updating to the patched version 098 or later, implementing additional CSRF protection measures, and monitoring administrative sessions for unauthorized configuration changes. The vulnerability demonstrates the critical importance of CSRF protection in administrative interfaces and serves as a reminder that even seemingly minor functionality gaps can create significant security risks in content management systems.
