id: CVE-2026-57582

info:
  name: GeoNetwork - Reflected Cross-Site Scripting
  author: DhiyaneshDk
  severity: high
  description: |
    GeoNetwork versions 4.4.5 through 4.4.11 are vulnerable to reflected cross-site scripting (XSS) in the public unauthenticated catalog search functionality. The uiconfig query parameter of the catalog.search endpoint is reflected into a JavaScript context without sufficient sanitization, allowing arbitrary JavaScript execution in a victim's browser.
  impact: |
    An unauthenticated attacker can craft a malicious URL that executes arbitrar JavaScript when opened by a victim. If a privileged GeoNetwork user such as an administrator visits the URL, the attacker may perform actions within the security context of that user.
  remediation: |
    Upgrade GeoNetwork to version 4.4.12 or later.
