CVE-2025-53266

Vulnerability

Overview

The Cron Logger plugin for WordPress (versions up to and including 1.3.0) suffers from a missing authorization vulnerability [1]. This is a broken access control issue where the plugin fails to properly verify that a user has the required privileges before allowing access to certain functions or data. The root cause is an incorrectly configured access control security level, which can be exploited by attackers without proper authentication.

Exploitation

An attacker can exploit this vulnerability by sending crafted requests to the WordPress site running the affected plugin. No prior authentication is required, making it accessible to any unauthenticated visitor. The reference notes that such vulnerabilities are frequently used in mass-exploit campaigns targeting thousands of websites regardless of size or popularity [1].

Impact

Successful exploitation allows an unprivileged user (or unauthenticated attacker) to perform actions that should be restricted to higher-privileged roles, such as administrators. This could include viewing or modifying sensitive log data, or executing other plugin-specific operations that compromise the site's security.

Mitigation

The vendor has not released a patched version beyond 1.3.0, so users are advised to immediately update the plugin if a newer version becomes available. If no update is possible, users should contact their hosting provider or web developer for assistance. Disabling the plugin until a fix is applied is also recommended [1].
