CVE-2024-32344Public exploitNetwork attack vector

Browser script execution via saved Language Edit value

Published Apr 17, 2024 · Updated Aug 2, 2024

Stored cross-site scripting in CMSimple 5.15 allows remote authenticated users to execute arbitrary script in a victim's browser. The Language settings Action form saves the crafted Edit value and renders it as active HTML instead of neutralizing script-capable markup. A settings-authorized account must store the payload, and script execution occurs only when the affected view is rendered.
