CVE-2025-53214

Vulnerability

Overview

The Sertifier Certificate & Badge Maker plugin for WordPress (versions up to and including 1.21) contains a missing authorization vulnerability. This flaw stems from incorrectly configured access control security levels, allowing exploitation of broken access control mechanisms [1].

Exploitation

Details

The vulnerability can be exploited without authentication, as the plugin fails to properly verify user permissions before executing certain higher-privileged actions. Attackers can target thousands of websites running the vulnerable plugin in mass-exploit campaigns, regardless of site traffic or popularity [1].

Impact

Successful exploitation enables an unprivileged attacker to perform actions that should require higher privileges, potentially leading to unauthorized certificate or badge creation, modification, or other administrative operations within the plugin's functionality [1].

Mitigation

The vendor has not released a patched version beyond 1.21 at the time of the plugin. Immediate action is recommended: update the plugin to the latest available version. If updating is not possible, users should contact their hosting provider or web developer for assistance [1].
