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.

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. Fixed in Vault 1.13.1, 1.12.5, and 1.11.9.

HashiCorp Vault's PKI mount issuer endpoints did not correctly authorize access to remove an issuer or modify issuer metadata, potentially resulting in denial of service of the PKI mount. This bug did not affect public or private key material, trust chains or certificate issuance. Fixed in Vault 1.13.1, 1.12.5, and 1.11.9.

HashiCorp Vault and Vault Enterprise versions 0.8.0 through 1.13.1 are vulnerable to an SQL injection attack when configuring the Microsoft SQL (MSSQL) Database Storage Backend. When configuring the MSSQL plugin through the local, certain parameters are not sanitized when passed to the user-provided MSSQL database. An attacker may modify these parameters to execute a malicious SQL command. This issue is fixed in versions 1.13.1, 1.12.5, and 1.11.9.

HashiCorp Vault and Vault Enterprise’s approle auth method allowed any authenticated user with access to an approle destroy endpoint to destroy the secret ID of any other role by providing the secret ID accessor. This vulnerability is fixed in Vault 1.13.0, 1.12.4, 1.11.8, 1.10.11 and above.

HashiCorp Vault and Vault Enterprise’s TLS certificate auth method did not initially load the optionally configured CRL issued by the role's CA into memory on startup, resulting in the revocation list not being checked if the CRL has not yet been retrieved. Fixed in 1.12.0, 1.11.4, 1.10.7, and 1.9.10.

HashiCorp Vault and Vault Enterprise through 1.7.4 and 1.8.3 allowed a user with write permission to an entity alias ID sharing a mount accessor with another user to acquire this other user’s policies by merging their identities. Fixed in Vault and Vault Enterprise 1.7.5 and 1.8.4.

HashiCorp Vault Enterprise 0.9.2 through 1.6.2 allowed the read of license metadata from DR secondaries without authentication. Fixed in 1.6.3.

HashiCorp Vault and Vault Enterprise’s UI erroneously cached and exposed user-viewed secrets between sessions in a single shared browser. Fixed in 1.8.0 and pending 1.7.4 / 1.6.6 releases.

HashiCorp Vault and Vault Enterprise Cassandra integrations (storage backend and database secrets engine plugin) did not validate TLS certificates when connecting to Cassandra clusters. Fixed in 1.6.4 and 1.7.1

HashiCorp Vault and Vault Enterprise disclosed the internal IP address of the Vault node when responding to some invalid, unauthenticated HTTP requests. Fixed in 1.6.2 & 1.5.7.

HashiCorp Vault and Vault Enterprise allowed for enumeration of Secrets Engine mount paths via unauthenticated HTTP requests. Fixed in 1.6.2 & 1.5.7.

The official vault docker images before 0.11.6 contain a blank password for a root user. System using the vault docker container deployed by affected versions of the docker image may allow a remote attacker to achieve root access with a blank password.

HashiCorp Vault and Vault Enterprise versions 0.8.3 and newer, when configured with the GCP GCE auth method, may be vulnerable to authentication bypass. Fixed in 1.2.5, 1.3.8, 1.4.4, and 1.5.1.

HashiCorp Vault and Vault Enterprise versions 0.7.1 and newer, when configured with the AWS IAM auth method, may be vulnerable to authentication bypass. Fixed in 1.2.5, 1.3.8, 1.4.4, and 1.5.1..

HashiCorp Vault and Vault Enterprise logged proxy environment variables that potentially included sensitive credentials. Fixed in 1.3.6 and 1.4.2.

HashiCorp Vault and Vault Enterprise versions 0.9.0 through 1.3.3 may, under certain circumstances, have an Entity's Group membership inadvertently include Groups the Entity no longer has permissions to. Fixed in 1.3.4.

HashiCorp Vault before 1.0.0 writes the master key to the server log in certain unusual or misconfigured scenarios in which incorrect data comes from the autoseal mechanism without an error being reported.
