Yoast — Vulnerabilities & Security Advisories 10

Yoast is a WordPress plugin focused on SEO optimization and content management. Historically, vulnerabilities have commonly included stored cross-site scripting (XSS), arbitrary file uploads, and privilege escalation flaws, with several instances allowing remote code execution. The plugin's extensive user base has made it a frequent target for exploitation. In 2020, a critical RCE vulnerability (CVE-2020-14040) affected versions prior to 14.1.1, enabling attackers to execute arbitrary code through crafted requests. While Yoast has addressed these issues through patches, its complex functionality and integration with WordPress core continue to present potential attack surfaces, requiring regular updates and input sanitization to mitigate risks.
