What is CVE-2021-32923?

HashiCorp Vault and Vault Enterprise have a vulnerability that permits the renewal of nearly-expired token leases and dynamic secret leases—specifically those within 1 second of their maximum time-to-live (TTL). This mismanagement leads to these tokens being erroneously categorized as non-expiring during future transactions. The issue affects multiple versions and can result in unintended access privileges if not addressed. The vulnerability has been resolved in versions 1.5.9, 1.6.5, and 1.7.2.
