A security update for WordPress was made public to address more than a dozen issues of various severity. To fix many security issues found in WordPress versions prior to 6.0.3, WordPress released a security update. Every update since WordPress 3.7 has also been made by WordPress.
WordPress security advisories about numerous vulnerabilities were released by the US Government’s National Vulnerability Database. A Cross-Site Scripting vulnerability, sometimes known as an XSS vulnerability, is one of many types that harm WordPress.
An online programme like WordPress commonly develops a cross-site scripting vulnerability when it doesn’t thoroughly examine (sanitise) what is entered into a form or submitted through an upload input. When a user visits a website, an attacker can send them a malicious script, which the user can then execute, giving the attacker access to sensitive data or cookies including user credentials. A Stored XSS vulnerability was also found, which is regarded as being worse than a typical XSS assault. When a user or logged-in user visits a website that has been subject to a stored XSS attack, the malicious script that was saved on the website is then executed.
Cross-Site Request Forgery (CSRF) is a third category of vulnerability that has been identified.
The vulnerabilities identified are as follows:
- XSS stored through wp-mail.php (post by email)
- Redirect in “wp nonce ays” is open
- In wp-mail.php, the email address of the sender is displayed
- Reflected XSS on Media Library through SQLi
