CVE-2025-53270

Vulnerability

Overview Cross-Site Request Forgery (CSRF) vulnerability exists in the Blend Media WordPress CTA plugin, also known as easy-sticky-sidebar, affecting versions from n/a through 1.7.0. The flaw arises because the plugin does not properly validate or require a unique token for state-changing requests, allowing an attacker to forge malicious requests that appear legitimate to the server [1].

Exploitation

Prerequisites Exploitation requires user interaction: a privileged user (e.g., an administrator) must be tricked into clicking a malicious link, visiting a specially crafted page, or submitting a form while authenticated to the WordPress site. No authentication is needed on the attacker's side, but the victim must have an active session with the target site. This vector is commonly used in mass-exploit campaigns targeting thousands of sites [1].

Impact

Successful exploitation could force the victim to unknowingly perform actions under their current session, such as modifying plugin settings, creating or deleting content, or changing user roles. The CVSS v3 base score is 4.3 (Medium), indicating a moderate risk due to the required user interaction and the potential for unwanted administrative actions [1].

Mitigation

The vendor has released version 1.7.1, which patches the CSRF vulnerability. Users are strongly advised to update the plugin immediately to 1.7.1 or later. For those unable to update, enabling auto-update for vulnerable plugins through Patchstack is recommended as a workaround [1].
