CVE-2025-6000
Vaulted Severance: Turning Audit Logs into Remote Shells
Amit Schendel
Senior Security ResearcherJan 1, 2026·5 min read·75 visits
Executive Summary (TL;DR)
If you have a root token (or 'sys/audit' write privs) in Vault, you can trick the audit logger into writing a binary payload to the plugin directory and executing it. This breaks the boundary between the Vault application and the underlying host OS, allowing a complete container escape or host compromise.
A critical privilege escalation vulnerability in HashiCorp Vault allows privileged operators to achieve Remote Code Execution (RCE) on the host system. By abusing the File Audit Device and Plugin System, an attacker can write executable audit logs to the plugin directory and execute them.
