When a malicious local user <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-50754-stored-cross-site-scripting-xss-vulnerability-leading-to-remote-code-execution-in-unisite-cms-5-0\/\"  data-wpil-monitor-id=\"74696\">executes low-privileged code<\/a>, the software could unintentionally follow a symbolic link that leads outside of its restricted path.

It is highly recommended that users promptly apply this patch to their systems. As a temporary mitigation, users can also utilize a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and block <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2024-7457-macos-authorization-model-exploit-leading-to-potential-mitm-attacks\/\"  data-wpil-monitor-id=\"80124\">potential exploit<\/a> attempts.
