CVE-2024-47847Public exploitNetwork attack vector

Cross-site scripting via unescaped rendered output

Published Oct 5, 2024 · Updated Oct 7, 2024

Cross-site scripting in Wikimedia Foundation MediaWiki Cargo before 3.6.1 allows remote attackers to inject scripts through generated pages. Multiple Cargo rendering paths insert attacker-controlled wiki data into generated HTML without context-appropriate output escaping. A crafted wiki import, page, or uploaded filename must reach an affected view; viewing that output executes script in the page origin.
