{"id":"BIT-vault-2023-25000","summary":"Vault Vulnerable to Cache-Timing Attacks During Seal and Unseal Operations","details":"HashiCorp Vault's implementation of Shamir's secret sharing used precomputed table lookups, and was vulnerable to cache-timing attacks. An attacker with access to, and the ability to observe a large number of unseal operations on the host through a side channel may reduce the search space of a brute force effort to recover the Shamir shares.
