  "summary": "CVE-2026-33750 is fixed in node-brace-expansion on 1 platform by DEBIAN-CVE-2026-33750 (version 2.0.3\u002B~1.1.2-1), released March 27, 2026. It is not reported as exploited. Patch Radar priority: High.",
  "title": "brace-expansion: Zero-step sequence causes process hang and memory exhaustion",
  "description": "The brace-expansion library generates arbitrary strings containing a common prefix and suffix. Prior to versions 5.0.5, 3.0.2, 2.0.3, and 1.1.13, a brace pattern with a zero step value (e.g., \u0060{1..2..0}\u0060) causes the sequence generation loop to run indefinitely, making the process hang for seconds and allocate heaps of memory. Versions 5.0.5, 3.0.2, 2.0.3, and 1.1.13 fix the issue. As a workaround, sanitize strings passed to \u0060expand()\u0060 to ensure a step value of \u00600\u0060 is not used.",
