CVE-2022-4676Public exploitNetwork attack vector

Contributor-level stored XSS via unescaped shortcode attributes

Published May 30, 2023 · Updated Jan 9, 2025

Stored cross-site scripting in OSM – OpenStreetMap before 6.0.6 allows remote authenticated users to execute script via a crafted shortcode. The shortcode renderer inserts attributes such as map_border into generated HTML without validating or escaping embedded attribute syntax. Contributor access is sufficient to store the payload, and execution requires another user to view or interact with the affected map content.
