Update your WordPress website now to address a critical vulnerability: Alert Priority Moderate
29 April 2015
WordPress has released a critical update to address a vulnerability that potentially leaves millions of websites worldwide open to attack.
The developers behind the content management system issued the update after researchers released a proof-of-concept exploit showing how an attacker could hijack a website running a vulnerable version of WordPress.
An attacker can insert script into a comment field on a WordPress website. The script is triggered when the infected comment is viewed. If the script is triggered by the website’s logged-in administrators, the attacker may be able to execute code on the server and change the administrators’ passwords, create new administrator accounts and access all other administrator privileges and tasks.
WordPress website administrators are advised to disable comments, including not approving any new comments until they apply the update. They should apply the update as quickly as possible.
Administrators should also strongly consider automating WordPress updates.
WordPress last week also issued a critical update to address multiple vulnerabilities, including a vulnerability that could enable an anonymous user to compromise a WordPress website.
