CVE-2022-43118 An XSS vulnerability in flatCore-CMS v2.1.0 allows attackers to execute arbitrary web scripts or HTML.

This vulnerability is highly recommended for disclosure at the vendor level. A remote attacker could inject malicious script codes in the logged-in user's account that could then be executed in the context of the current site. In particular, XSS flaws can be exploited to steal sensitive data from your site's database, conduct phishing attacks, or even install malware on a site's server. XSS flaws are also a common vector for generating click fraud, where attackers could inject false content into your site's HTML via a crafted XSS payload and then direct users to that content via a fake ad or recommendation. XSS vulnerabilities are often found in third-party software components of web applications, which makes patching these issues a critical step to ensuring the ongoing integrity of your site.
