Extend Themes — Vulnerabilities & Security Advisories 7

Extend Themes develops WordPress themes and website templates for businesses and content creators. Historically, their products have been susceptible to multiple remote code execution (RCE) vulnerabilities, cross-site scripting (XSS) flaws, and privilege escalation issues, often stemming from insufficient input validation and improper access controls. With seven CVEs documented, these security gaps have allowed attackers to execute arbitrary code, steal session cookies, and gain unauthorized administrative access. While no major public incidents have been widely reported, the consistent pattern of vulnerabilities in their extensions suggests a need for more rigorous security testing and input sanitization practices to protect end users.
