What is CVE-2020-29240?

Lepton-CMS version 4.7.0 has a significant cross-site scripting (XSS) vulnerability that allows attackers to inject malicious scripts via the URL field on the admin page. This issue becomes exploitable when an administrative user accesses specific sections, such as the Menu-Pages-Pages Overview. When the affected page is loaded, the injected script executes within the context of the admin's session, potentially allowing unauthorized actions or data exposure. Website administrators should apply recommended security patches and regularly audit their systems to mitigate the risk of exploitation.
