info:
  name: XWiki Platform - Cross-Site Scripting
  author: ritikchaddha
  severity: medium
  description: |
    XWiki Platform versions >= 4.2-milestone-3 and < 16.4.8, >= 16.5.0-rc-1 and < 16.10.6, and >= 17.0.0-rc-1 and < 17.3.0-rc-1 are vulnerable to reflected XSS in two templates. The vulnerability allows an attacker to execute malicious JavaScript code in the context of the victim's session by getting the victim to visit an attacker-controlled URL.
  impact: |
    Attackers can execute malicious JavaScript in victim sessions by crafting URLs with XSS payloads in translationPrefix, extensionId, or extensionVersionConstraint parameters.
  remediation: |
    Upgrade to XWiki Platform version 16.4.8, 16.10.6, or 17.3.0-rc-1 or later that properly sanitizes user input in templates.
