A flaw was found in the Hashicorp vault.

A flaw was found in the Hashicorp vault. This flaw allows an attacker with access to and the ability to observe a large number of unseal operations on the host through a side channel to reduce the search space of a brute-force effort to recover the Shamir shares.

HashiCorp Vault and Vault Enterprise 1.12.0 and newer are vulnerable to a denial of service through memory exhaustion of the host when handling large unauthenticated and authenticated HTTP requests from a client. Vault will attempt to map the request to memory, resulting in the exhaustion of available memory on the host, which may cause Vault to crash.

Fixed in Vault 1.15.4, 1.14.8, 1.13.12.

Vault and Vault Enterprise's (Vault) key-value v2 (kv-v2) diff viewer allowed HTML injection into the Vault web UI through key values. This vulnerability, CVE-2023-2121, is fixed in Vault 1.14.0, 1.13.3, 1.12.7, and 1.11.11.
