CVE-2026-13149 (GCVE-0-2026-13149)
Vulnerability from cvelistv5 – Published: 2026-06-30 08:30 – Updated: 2026-06-30 12:43
VLAI?
Summary
brace-expansion through 5.0.6 is vulnerable to denial of service. The expand() function exhibits exponential-time complexity in the number of consecutive non-expanding '{}' brace groups. An attacker who passes a crafted string to expand(), directly or transitively, can cause significant CPU consumption and event-loop blocking. The max option does not mitigate this, as it bounds the output size rather than the recursion work.
