soroban-poseidon 安全漏洞

Soroban-Poseidon is a Poseidon hash function library developed by Stellar for smart contracts. Soroban-Poseidon has a security vulnerability, which stems from Poseidon V1 accepting variable-length inputs without using injective padding, potentially leading to simple hash collisions...
