CVE-2022-0448Public exploitNetwork attack vector

Stored cross-site scripting via unescaped License ID

Published Mar 7, 2022 · Updated Aug 2, 2024

Stored cross-site scripting in CodePeople CP Blocks before 1.0.15 allows remote authenticated administrators to execute browser scripts. The License ID setting stores browser-supplied content without sanitizing it and renders the stored value without output escaping. Administrator-level access can persist a payload even when unfiltered_html is disabled; execution occurs when the affected license interface is revisited.
