      "value": "The brace-expansion library generates arbitrary strings containing a common prefix and suffix. Prior to 1.1.18, 2.1.4, 3.0.6, and 5.0.9, expand() does not apply maxLength while constructing comma-alternative intermediate arrays or padded sequences, allowing attacker-controlled input to exhaust memory or block the event loop. The fix for CVE-2026-14257 is bypassed by the vulnerability. This issue is fixed in versions 1.1.18, 2.1.4, 3.0.6, and 5.0.9."

Antes de 1.1.18, 2.1.4, 3.0.6 y 5.0.9, expand() no aplica maxLength mientras construye arrays intermedios de alternativas de coma o secuencias rellenadas, permitiendo que la entrada controlada por el atacante agote la memoria o bloquee el bucle de eventos. La corrección para CVE-2026-14257 es eludida por la vulnerabilidad. Este problema está corregido en las versiones 1.1.18, 2.1.4, 3.0.6 y 5.0.9."
