1.15.16 Enterprise

October 09, 2024

SECURITY:

• secrets/identity: A privileged Vault operator with write permissions to the root namespace's identity endpoint could escalate their privileges to Vault's root policy (CVE-2024-9180) HCSEC-2024-21

IMPROVEMENTS:

• core: log at level ERROR rather than INFO when all seals are unhealthy. [GH-28564]

BUG FIXES:

• auth/cert: When using ocsp_ca_certificates, an error was produced though extra certs validation succeeded. [GH-28597]
• auth/token: Fix token TTL calculation so that it uses max_lease_ttl tune value for tokens created via auth/token/create. [GH-28498]

1.15.15 Enterprise

September 25, 2024

SECURITY:

• secrets/ssh: require valid_principals to contain a value or default_user be set by default to guard against potentially insecure configurations. allow_empty_principals can be used for backwards compatibility [HCSEC-2024-20](https://discuss.hashicorp.com/t/hcsec-2024-20-vault-ssh-secrets-engine-configuration-did-not-restrict-valid-principals-by-default/7025

CHANGES:

• core: Bump Go version to 1.22.7.
• secrets/ssh: Add a flag, allow_empty_principals to allow keys or certs to apply to any user/principal. [GH-28466]

BUG FIXES:

• secret/aws: Fixed potential panic after step-down and the queue has not repopulated. [GH-28330]
• auth/cert: During certificate validation, OCSP requests are debug logged even if Vault's log level is above DEBUG. [GH-28450]
• auth/cert: ocsp_ca_certificates field was not honored when validating OCSP responses signed by a CA that did not issue the certificate. [GH-28309]
• auth: Updated error handling for missing login credentials in AppRole and UserPass auth methods to return a 400 error instead of a 500 error. [GH-28441]
• core: Fixed an issue where maximum request duration timeout was not being added to all requests containing strings sys/monitor and sys/events. With this change, timeout is now added to all requests except monitor and events endpoint. [GH-28230]

1.15.14 Enterprise

August 29, 2024

CHANGES:

• activity (enterprise): filter all fields in client count responses by the request namespace [GH-27790]
• core: Bump Go version to 1.22.6

IMPROVEMENTS:

• activity log: Changes how new client counts in the current month are estimated, in order to return more visibly sensible totals. [GH-27547]
