Detailed vulnerability description
The vulnerability allows a remote attacker to disclose sensitive information from internal services.
The vulnerability exists due to server-side request forgery (SSRF) in plugin/LiveLinks/proxy.php when processing a user-supplied URL that returns an HTTP redirect. A remote attacker can supply a crafted URL that redirects to an internal endpoint to disclose sensitive information from internal services.
The issue occurs because the redirect target is fetched without re-validation, and the returned response can include cloud metadata such as IAM credentials.
