CVE-2025-53264

Vulnerability

Overview

The ONet Regenerate Thumbnails plugin for WordPress (versions through 1.5) contains a Cross-Site Request Forgery (CSRF) vulnerability. This flaw arises from insufficient validation of requests, enabling an attacker to trick a logged-in administrator into performing unintended actions without their consent [1].

Exploitation

Details

Exploitation requires user interaction: a privileged user must click a malicious link, visit a crafted page, or submit a specially designed form while authenticated to the WordPress site. The attacker does not need direct access to the site but can leverage social engineering to deliver the payload [1].

Impact

Successful exploitation allows an attacker to force the victim to execute unwanted actions under their current authentication level. This could include modifying plugin settings, regenerating thumbnails, or other administrative operations, potentially leading to further compromise [1].

Mitigation

The vendor has not released a patched version as of the advisory date. Users are advised to update the plugin immediately if a fix becomes available, or to contact their hosting provider or web developer for assistance. Until then, consider disabling the plugin or implementing additional CSRF protections [1].
