CVE-2024-40347Public exploitNetwork attack vector

Browser script execution via unneutralized htmlid parameter

Published Jul 20, 2024 · Updated Mar 18, 2025

Reflected XSS in Hyland Alfresco Platform 23.2.1-r96 allows attackers to execute script in a user's browser through htmlid. The folder-metadata endpoint places the htmlid value into generated page content without neutralizing crafted markup, enabling script-element injection. A signed-in user must open a crafted URL containing a valid SpacesStore node reference, after which the script runs in that user's browser context.
