Loading vulnerability details...
Affected versions of node-sass are vulnerable to Denial of Service (DoS). Crafted objects passed to the renderSync function may trigger C++ assertions in CustomImporterBridge::get_importer_entry and CustomImporterBridge::post_process_return_value that crash the Node process. This may allow attackers to crash the system's running Node process and lead to Denial of Service.
Upgrade to version 4.13.1 or later

Upgrade to version 4.13.1 or later
This high-severity vulnerability could allow attackers to gain unauthorized access, execute arbitrary code, or compromise data integrity. Prompt remediation is strongly recommended.
Apply security patches to version 4.13.1 immediately
Isolate affected systems from untrusted networks until patching is complete
Implement enhanced monitoring for exploitation attempts and unusual behavior
