CVE-2025-25120

Vulnerability

The Slide Banners WordPress plugin (versions <= 1.3) contains a missing authorization vulnerability. The plugin fails to properly enforce access control checks, allowing users to exploit incorrectly configured access control security levels. The vulnerability exists in the plugin's code that handles banner management operations without verifying the user's capabilities.

Exploitation

An attacker must have network access to the WordPress site and an active user session. No special privileges are required beyond standard user access. The attacker can send crafted requests to the vulnerable endpoints to perform unauthorized actions, such as modifying or accessing banner configurations without proper authorization checks.

Impact

Successful exploitation allows an attacker to bypass access controls and perform actions normally restricted to higher-privileged users. This could lead to unauthorized modification of slide banners, information disclosure regarding plugin settings, or other operations the plugin permits without proper capability checks.

Mitigation

The Slide Banners plugin has been closed and removed from the WordPress.org plugin directory as of January 23, 2025, due to a security issue [1]. No patched version is available through the official directory. Users should immediately uninstall the plugin and migrate to an alternative solution. Since no fix has been released, uninstallation is the only complete mitigation [1].
