Technical details
This is a stored cross-site scripting (XSS) vulnerability in the helpers.markdown_extract() function, which processes markdown input and wraps it in HTML without sufficient output encoding. The vulnerability affects dataset, resource, organization, and group pages, as well as any extension using this helper. An authenticated attacker can inject JavaScript payload into description fields; when a victim visits the page, the script executes in their browser context with their privileges. The vulnerability requires authentication and user interaction (victim viewing the page). Patches are available in CKAN 2.10.9 and 2.11.4.
