Stored script execution via unsanitized biography

Published Jul 14, 2022 · Updated Apr 15, 2025

Stored cross-site scripting in Simple E-Learning System 1.0 allows remote authenticated users to inject scripts through the Bio field. The /vcs/claire_blake endpoint stores the Bio value and renders it without neutralizing embedded HTML or JavaScript. A registered user must save a crafted biography, and another user must view the affected profile for the script to execute in that viewer's browser.
