ckeditor — Vulnerabilities & Security Advisories 19

CKEditor serves as a WYSIWYG text editor component integrated into web applications for content creation. Historically, it has been susceptible to cross-site scripting (XSS) vulnerabilities due to improper input sanitization, with several instances allowing remote code execution (RCE) through crafted payloads. Privilege escalation vulnerabilities have also been documented in certain versions. The project maintains a security-focused approach, with regular updates addressing identified flaws. While 19 CVEs exist on record, most relate to older versions; recent releases demonstrate improved security practices. The editor's extensive customization options and third-party plugin ecosystem introduce additional potential attack surfaces requiring careful configuration and maintenance to mitigate risks.
