CVE-2026-13149
High · CVSS 7.7 (CVSS 4.0)EPSS 0.36%, 30th percentilePublished Updated Assigner: seal
Description
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.
