CVE-2020-12707 describes a Cross-Site Scripting (XSS) vulnerability in LeptonCMS 4.5.0, specifically within the modules/wysiwyg/save.php component. This medium-severity flaw (CVSS 6.1) allows attackers to execute arbitrary JavaScript by leveraging HTML event handlers, bypassing the system's inadequate defense of merely stripping SCRIPT tags. The vulnerability requires user interaction (UI:R) but can be exploited remotely (AV:N), potentially leading to information disclosure and data integrity issues. While not on the CISA KEV list and lacking significant community discussion or media coverage, a public exploit (EDB-48250) exists, indicating its exploitability.
