Vault and Vault Enterprise did not properly validate the JSON Web Token (JWT) role-bound audience claim when using the Vault JWT auth method. This may have resulted in Vault validating a JWT the audience and role-bound claims do not match, allowing an invalid login to succeed when it should have been rejected.
This vulnerability, CVE-2024-5798, was fixed in Vault and Vault Enterprise 1.17.0, 1.16.3, and 1.15.9
