CVE-2026-93333
Vault audit device prefix vulnerable to log injection
Description
Vault's audit devices did not validate the contents of a configured audit log prefix and did not consistently enforce the server-level setting that restricts audit log prefixing. This may allow a privileged operator to inject content into audit logs, potentially leading to forged or misleading audit records. This vulnerability (CVE-2026-93333) is fixed in Vault Community Edition 2.2.2 and Vault Enterprise 2.2.2, 1.21.14, and 1.19.25.
