Report: CVE-2026-45149 - brace-expansion: Large numeric range defeats documented `max` DoS protection - Analysis
CVE ID :CVE-2026-45149 Published : May 29, 2026, 8:16 p.m. | 45 minutes ago Description :The brace-expansion library generates arbitrary strings containing a common prefix and suffix. From 5.0.0 to before 5.0.6, the max option was being applied too late. When expanding a single large numeric range like {1..10000000}, the sequence generation loop generates all 10 million intermediate elements before the max limit is applied With max=10, the output is correctly limited to 10 items, but the process still allocates ~505 MB and spends ~800ms building the full intermediate array. This vulnerability is fixed in 5.0.6. Severity: 6.5 | MEDIUM Visit the link for more details, such as CVSS details, affected products, timeline, and more...
