However, despite its convenience, the Updater plugin prior to version 1.35 was susceptible to the CVE-2017-18565 vulnerability. This vulnerability , discovered in 2017, represents a Cross-Site Scripting (XSS) issue that can cause malicious JavaScript code to be injected and executed entirely in the context of the victim's web browser. The code is typically hidden, making it challenging to identify for a regular user, and can result in a script leaking sensitive user data, changing website content, or performing other malicious activities.

In particular, hackers can use it to launch attacks on the site users themselves by injecting a malicious script into the Updater's code.

This issue can be exacerbated further for multi-tenant environments or web hosting environments.
