Name of the Vulnerable Software and Affected Versions: WordPress Pie Register plugin versions ≤ 3.7.1.4 Description: An authentication bypass issue exists that allows unauthenticated attackers to impersonate arbitrary users by submitting a crafted POST request to the "login endpoint". By setting `social site` = true and manipulating the `user id social site` parameter, an attacker can generate a valid WordPress session cookie for any user ID, including administrators. Once authenticated, the attacker may exploit plugin upload functionality to install a malicious plugin containing arbitrary PHP code, resulting in remote code execution on the underlying server. Recommendations: For WordPress Pie Register plugin versions ≤ 3.7.1.4, update to a version greater than 3.7.1.4 to resolve the issue. As a temporary workaround, consider disabling the plugin upload functionality to minimize the risk of exploitation. Restrict access to the login endpoint to prevent unauthorized access.
