CVE-2026-4598

Versions of the package jsrsasign before 11.1.1 are vulnerable to Infinite loop via the bnModInverse function in ext/jsbn2.js when the BigInteger.modInverse implementation receives zero or negative inputs, allowing an attacker to hang the process permanently by supplying such crafted values (e.g., modInverse(0, m) or modInverse(-1, m)).

Versiones del paquete jsrsasign anteriores a la 11.1.1 son vulnerables a un bucle infinito a través de la función bnModInverse en ext/jsbn2.js cuando la implementación de BigInteger.modInverse recibe entradas cero o negativas, permitiendo a un atacante colgar el proceso permanentemente al suministrar dichos valores manipulados (p. ej., modInverse(0, m) o modInverse(-1, m)).
