An arbitrary file upload vulnerability in LEPTON v7.0.0 allows authenticated attackers to execute arbitrary PHP code by uploading this code to the backend/languages/index.php languages area.

Cross Site Scripting (XSS) vulnerability in backend/pages/modify.php in Lepton-CMS version 4.7.0, allows remote attackers to execute arbitrary code.

Lepton-CMS 4.7.0 is affected by cross-site scripting (XSS). An attacker can inject the XSS payload in the URL field of the admin page and each time an admin visits the Menu-Pages-Pages Overview section, the XSS will be triggered.

An XSS vulnerability exists in modules/wysiwyg/save.php of LeptonCMS 4.5.0. This can be exploited because the only security measure used against XSS is the stripping of SCRIPT elements. A malicious actor can use HTML event handlers to run JavaScript instead of using SCRIPT elements.

Multiple cross-site scripting (XSS) vulnerabilities exist in LeptonCMS before 4.6.0.

Directory traversal vulnerability in account/preferences.php in LEPTON before 1.1.4 allows remote attackers to include and execute arbitrary files via a .. (dot dot) in the language parameter.

SQL injection vulnerability in modules/news/rss.php in LEPTON before 1.1.4 allows remote attackers to execute arbitrary SQL commands via the group_id parameter.

Multiple cross-site scripting (XSS) vulnerabilities in LEPTON 1.1.3 and other versions before 1.1.4 allow remote attackers to inject arbitrary web script or HTML via the (1) message parameter to admins/login/forgot/index.php, or the (2) display_name or (3) email parameter to account/preferences.php.

Cross-site scripting (XSS) vulnerability in WebsiteBaker before 2.8, as used in LEPTON and possibly other products, allows remote attackers to inject arbitrary web script or HTML via unknown vectors, a different vulnerability than CVE-2006-2307.
