CVE-2022-48197Public exploitNetwork attack vector

Reflected XSS via unencoded mode parameter

Published Jan 2, 2023 · Updated Oct 28, 2024

Reflected XSS in YUI2 Sandbox examples allows remote attackers to execute script in a victim's browser through a crafted mode parameter. The sandbox/treeview/inc-rightbar.php template copies the mode query value into multiple link href attributes without HTML encoding. Exploitation requires a user to open an attacker-crafted URL for a separately deployed PHP Sandbox example; YUI2 distributions, TreeView, and the library itself are unaffected.
