CVE-2022-24967Network attack vector

Cross-user browser actions via stored JavaScript

Published May 29, 2022 · Updated May 30, 2025

Stored XSS in Black Rainbow NIMBUS before 3.7.0 allows remote authenticated users to execute scripts in another user's browser. Several NIMBUS features retain attacker-supplied JavaScript without neutralization and render it when another user opens affected content. Authenticated feature access is required to plant the payload, and victim interaction enables session actions, data exfiltration, and browser-originated network requests.
