CVE-2021-32923: Hashicorp Vault

High severity, CVSS 7.4. EPSS: 1.4% chance of exploitation in the next 30 days.

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.

Affected products

• Hashicorp Vault: from 0.10.0, before 1.5.9 (fixed in 1.5.9); from 1.6.0, before 1.6.5 (fixed in 1.6.5); from 1.7.0, before 1.7.2 (fixed in 1.7.2)
