Lepton-cms : Security Vulnerabilities, CVEs, CVSS score >= 6

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.

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.

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.

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.
