CVE-2020-22986Known exploitationPublic exploitNetwork attack vector

Browser script execution via unencoded scraped content

Published May 12, 2022 · Updated Jul 9, 2026

Cross-site scripting in MicroStrategy Web SDK 10.11 and earlier allows remote attackers to execute browser scripts via searchString. The wikiScrapper task treats an HTTP or HTTPS searchString as a source URL, scrapes a specially structured page, and renders its content without output encoding. No authentication is required, but exploitation requires a victim to open a crafted task URL pointing to attacker-controlled HTML, enabling script execution in the application's browser origin.
