CVE-2026-102277

The brace-expansion library is vulnerable to a recoverable CPU denial of service due to how the expand function processes specific patterns. Prior to versions 1.1.21, 2.1.7, 3.0.9, and 5.0.12 , providing untrusted {a},b}-shaped patterns with numerous trailing closing braces causes the library to ...

brace-expansion: DoS via unbounded intermediate arrays, bypassing the CVE-2026-14257 mitigation

A flaw was found in the brace-expansion library. The expand function does not apply maxLength when constructing comma-alternative intermediate arrays or padded sequences, allowing attacker-controlled input to exhaust memory or block the event loop, resulting in a denial of service. This issue is...
