CVE-2020-22985Known exploitationPublic exploitNetwork attack vector

Reflected XSS via getESRIExtraConfig key parameter

Published May 12, 2022 · Updated Jul 9, 2026

Cross-site scripting in MicroStrategy Web SDK 10.11 and earlier allows remote attackers to run script via the getESRIExtraConfig key parameter. The public record identifies the task and parameter but does not disclose the code path or exact missing output-neutralization operation. No authentication is required, but a victim must open attacker-controlled content; successful exploitation runs script in the affected web origin.
