Gliffy — Vulnerabilities & Security Advisories 3

Gliffy serves as a web-based diagramming tool primarily used for creating flowcharts, UML diagrams, and other visual documentation. Historically, the platform has been susceptible to cross-site scripting (XSS) vulnerabilities and remote code execution flaws, often stemming from improper input validation and insufficient sanitization of user-supplied data. While no major public security incidents have been widely reported, the three documented CVEs highlight persistent risks in web application security, particularly around injection-based attacks and inadequate access controls. These vulnerabilities could potentially allow attackers to execute arbitrary code, manipulate sessions, or escalate privileges within the application environment.
