How the CVE Works
The vulnerability (CVE-2025-XXXX) in Hashicorp Vault allows a privileged operator with `sys/audit` write permissions to execute arbitrary code on the host system. This occurs when a plugin directory is configured in Vault, enabling malicious plugin uploads. Attackers can leverage this misconfiguration to inject and execute malicious binaries, bypassing Vault’s security controls. The flaw stems from insufficient validation of plugin paths, allowing path traversal or unauthorized binary execution.
