Summary

CVE-2025-54794 is a high-severity Path Traversal (CWE-22) vulnerability in Anthropic Claude Code. Its CVSS base score is 7.7 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 44% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

This vulnerability is AI-related — categorised as Enterprise AI Assistants; in the Privacy and Disclosure risk domain.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-54794 is a path traversal vulnerability (CWE-22) in Claude Code, an agentic coding tool developed by Anthropic. Versions below 0.2.111 use prefix matching for path validation instead of canonical path comparison, allowing attackers to bypass directory restrictions and access files outside the current working directory (CWD). The vulnerability carries a CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N) and was published on 2025-08-05.

Exploitation is possible by remote attackers requiring no privileges or user interaction. It depends on the presence of—or ability to create—a directory with the same prefix as the CWD, combined with the attacker's ability to insert untrusted content into a Claude Code context window. Successful attacks enable high confidentiality and integrity impacts, such as reading sensitive files or modifying data outside the restricted directory.

The vulnerability is addressed in Claude Code version 0.2.111. Additional details on the issue and remediation are available in the GitHub security advisory at https://github.com/anthropics/claude-code/security/advisories/GHSA-pmw4-pwvc-3hx2.

Vulnerability Data

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…

Mitigating Controls (NIST 800-53 r5) AI

Enforces the intended directory access authorizations that path traversal would otherwise bypass.

Input validation directly neutralizes special path elements before pathname construction occurs.

Least privilege reduces the impact of any unauthorized file access obtained via traversal.

PR.PS-02 partial match
prevents

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

PR.AA-05 none match
prevents

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

finds

Security testing in development catches path traversal via static/dynamic analysis.

prevents

Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.

prevents

Application security requirements include rules for safe file handling and canonicalization.

prevents

Secure architecture principles require least-privilege file access and directory isolation.

prevents

Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.

mitigates

Information access restriction limits which files an application may read or write.
