CVE-2025-59551

Vulnerability

Overview CVE-2025-59551 is a missing authorization vulnerability in the WordPress plugin Revive.so, affecting versions from n/a through 2.0.6. The plugin fails to properly enforce access control checks, allowing unauthenticated or low-privileged users to perform actions that should require higher privileges. This is a classic broken access control issue, where the software does not verify that the user has the necessary permissions are held before executing a sensitive function [1].

Exploitation

An attacker can exploit this vulnerability without needing any authentication or special privileges. The missing authorization check means that any visitor to a WordPress site running the vulnerable plugin can trigger certain higher-privileged actions. This type of vulnerability is often used in mass-exploit campaigns, where attackers target thousands of sites simultaneously, regardless of their size or popularity [1].

Impact

Successful exploitation allows an attacker to perform actions that should be restricted to administrators or other privileged roles. The exact impact depends on the specific function that lacks authorization, but it could include modifying plugin settings, accessing sensitive data, or other unauthorized operations. The CVSS v3 base score is 4.3 (Medium), indicating a moderate severity [1].

Mitigation

The vulnerability has been addressed in version 2.0.7 of the Revive.so plugin. Users are strongly advised to update to this version or later immediately. For those unable to update, contacting a hosting provider or web developer for assistance is recommended. Patchstack users can enable auto-updates for vulnerable plugins to stay protected [1].
