CVE-2026-13149

A flaw was found in brace-expansion. An attacker can exploit a vulnerability in the `expand()` function by providing a specially crafted string. This string, containing consecutive non-expanding brace groups, can trigger exponential-time complexity, leading to significant CPU consumption and event-loop blocking. This can result in a Denial of Service (DoS) for the affected system.

CVE-2026-48936

A flaw was found in Node.js. The Node.js Permission API can allow a local server to be started through a Unix domain socket, even when the `--allow-net` permission is not explicitly granted. This bypasses intended security restrictions, potentially leading to unintended local network exposure or integrity impact.
