It is classified under OWASP Top 10 A3: Injection and has a CVSS severity score of 7.1, indicating moderate danger with a likelihood of exploitation.
Exploitation requires user interaction, such as a privileged user clicking a malicious link, visiting a crafted page, or submitting a form, but no authentication is required to initiate the attack.
How can this vulnerability impact me? :
This vulnerability can impact you by allowing attackers to execute malicious scripts on your website, which can lead to unauthorized redirects, display of unwanted advertisements, or other harmful HTML payloads.
Such attacks can compromise the integrity and trustworthiness of your website, potentially harming your users and damaging your reputation.
Since exploitation requires user interaction but no authentication, attackers can target visitors or privileged users to trigger the malicious scripts.
