CVE-2020-12757

Extended GCP credential access via ignored TTL

Published Jun 10, 2020 · Updated Aug 4, 2024

Incorrect lease handling in HashiCorp Vault 1.4.0 and 1.4.1 allows attackers to retain GCP credentials longer than configured. The service-account-key response path fails to copy the GCP Secrets Engine's configured TTL and maximum TTL into the generated secret, leaving Vault's default lease duration in effect. The flaw requires the GCP Secrets Engine and a key request without an explicit TTL; affected credentials remain usable for GCP actions beyond the configured lease.
