Its code-sandbox component relies only on an application-level soft limit, a 500ms polling interval, for memory management and lacks OS-level constraints such as cgroups or kernel-level namespaces. Attackers can bypass memory checks through time-window attacks or exhaust the JavaScript worker pool with concurrent CPU-intensive requests, causing a complete Denial of Service for legitimate users.","solution":"N/A -- no mitigation discussed in source.
