zopefoundation — Vulnerabilities & Security Advisories 20

The Zope Foundation develops Zope, a Python-based content management framework and application server primarily used for building complex web applications with robust security features. Historically, its vulnerabilities have commonly included cross-site scripting (XSS), remote code execution (RCE), and privilege escalation, often stemming from input validation flaws and insecure default configurations. While Zope's security model emphasizes granular permissions and has generally avoided major high-profile incidents, the 17 recorded CVEs highlight ongoing challenges in maintaining security across its extensive feature set, particularly in third-party extensions and legacy components.
