WordPress 4.7 "Content Injection Vulnerability" - Fixed!Just recently, security vendor Sucuri disclosed a severe "Content Injection Vulnerability" in the WordPress REST API that allows remote unauthorized hackers to modify the content of any page or post within a WordPress web site as well as privilege escalation that could affect millions of web sites worldwide.
Is your WordPress web site vulnerable to the attack?The WordPress REST API was recently added and enabled by default on WordPress 4.7.0.
If you are using WordPress versions: 4.7.0 or 4.7.1 you should immediately update to version 4.7.2 where WordPress patched the "then-secret zero-day vulnerability" security flaw.
What's this all about?One of these WordPress REST API endpoints allows access (via the API) to view, edit, delete and create posts.
Within this particular endpoint, a subtle bug allows visitors to edit any post on the site.
That could lead to the creation of two new vulnerabilities "Remote privilege escalation" and "Content injection bugs".
For the technical details of the injection, you can check Sucuri's post here.
