CVE-2023-51540

Name of the Vulnerable Software and Affected Versions Kunal Nagar Custom 404 Pro versions 3.10.0 and earlier

Description The issue is related to improper neutralization of input during web page generation, which allows stored cross-site scripting (XSS). This means that an attacker can inject malicious scripts into the website, potentially leading to unauthorized access or other malicious activities. The estimated number of potentially affected devices worldwide is not available. There is no information about real-world incidents where this issue was exploited.

Recommendations For versions 3.10.0 and earlier, update to a version later than 3.10.0 to resolve the issue. As a temporary workaround, consider restricting user input to prevent malicious scripts from being injected into the website. Avoid using potentially vulnerable functions or parameters that may allow stored XSS until the issue is resolved. At the moment, there is no other information about additional mitigation measures.
