Administrator-browser script execution via public project name
Published Sep 24, 2022 · Updated Apr 25, 2025
Stored XSS in renlm MyGraph before 1.0.4 allows remote authenticated users to execute script in an administrator's browser. The New Project workflow stores the Project name without neutralizing script markup, and a public project renders that value in an administrator's browser. Exploitation requires a logged-in attacker and administrator interaction; the advisory describes information theft and phishing, while its claimed server-side code execution mechanism is undisclosed.
