Overview
CVE-2025-12569 is an Open Redirect vulnerability affecting the “Guest posting / Frontend Posting / Front Editor” WordPress plugin in versions prior to 5.0.0. This vulnerability allows attackers to redirect users to arbitrary websites by exploiting a lack of input validation in a redirect parameter. This can be used in phishing attacks or to trick users into visiting malicious websites that appear legitimate.
Technical Details
The vulnerability stems from the plugin’s failure to properly validate a parameter before redirecting the user to its value. Specifically, the plugin uses a user-supplied input (likely through a GET or POST request) without sanitizing or verifying its intended destination. This allows an attacker to craft a malicious URL that, when clicked, redirects the user to a website controlled by the attacker. This type of vulnerability is particularly dangerous because it can be easily exploited, even by individuals with limited technical skills.
The vulnerable code is located within the plugin’s core functionality that handles redirects after certain actions, such as submitting a guest post. The exact parameter and code location are detailed in the reference link.

Currently, the CVSS score for CVE-2025-12569 is N/A.
