Doc Text:
A flaw was found in the HashiCorp Vault and Vault Enterprise. The vault could allow a remote attacker to bypass security restrictions caused by a renewal logic flaw when a token lease or dynamic secret lease was renewed inside the last second of its maximum TTL. By sending a specially crafted request, an attacker can bypass authentication validation and gain access to the system.

Description Pedro Sampaio 2021-06-04 18:18:40 UTC 
HashiCorp Vault and Vault Enterprise allowed the renewal of nearly-expired token leases and dynamic secret leases (specifically, those within 1 second of their maximum TTL), which caused them to be incorrectly treated as non-expiring during subsequent use. Fixed in 1.5.9, 1.6.5, and 1.7.2.
