NVD Description

Note: Versions mentioned in the description apply only to the upstream vault-1.20 package and not the vault-1.20 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

A malicious user may submit a specially-crafted complex payload that otherwise meets the default request size limit which results in excessive memory and CPU consumption of Vault. This may lead to a timeout in Vault’s auditing subroutine, potentially resulting in the Vault server to become unresponsive. This vulnerability, CVE-2025-6203, is fixed in Vault Community Edition 1.20.3 and Vault Enterprise 1.20.3, 1.19.9, 1.18.14, and 1.16.25.
