HashiCorp Vault and Vault Enterprise inbound client requests triggering a policy check can lead to an unbounded consumption of memory. A large number of these requests may lead to denial-of-service. Fixed in Vault 1.15.2, 1.14.6, and 1.13.10.

## Affected packages

- `github.com/hashicorp/vault < 1.13.10`
- `github.com/hashicorp/vault >= 1.14.0, < 1.14.6`
