CVE-2025-54794

9.1 · CRITICAL
Published Aug 5, 2025 anthropic CWE-22 EPSS 0.88% (56th pctl)

Overview

CVE-2025-54794 is a critical-severity vulnerability affecting anthropic claude_code. It was published on August 5, 2025 and has a CVSS 3.1 base score of 9.1 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.1, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical Description

Claude Code is an agentic coding tool. In versions below 0.2.111, a path validation flaw using prefix matching instead of canonical path comparison, makes it possible to bypass directory restrictions and access files outside the CWD. Successful exploitation depends on the presence of (or ability to create) a directory with the same prefix as the CWD and the ability to add untrusted content into a Claude Code context window. This is fixed in version 0.2.111.

Remediation

Check the references section for vendor advisories and patches from anthropic. Update claude_code to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
