Summary

CVE-2025-65713 is a medium-severity Path Traversal (CWE-22) vulnerability in Home-Assistant Home-Assistant. Its CVSS base score is 4.0 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique File and Directory Discovery (T1083); ranked at the 30th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

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

Vulnerability Data

Home Assistant Core before v2025.8.0 is vulnerable to Directory Traversal. The Downloader integration does not fully validate file paths during concatenation, leaving a path traversal vulnerability.

CWE(s)

Related Threats

MITRE ATT&CK Enterprise TechniquesAI

T1083 File and Directory Discovery Discovery
Adversaries may enumerate files and directories or may search in specific locations of a host or network share for certain information within a file system.
Why these techniques?

Directory traversal in the Downloader integration enables File and Directory Discovery (T1083) by allowing an attacker to read arbitrary files outside the intended directory through path manipulation during file path concatenation.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires validation of file path inputs to reject traversal sequences before concatenation occurs in the Downloader integration.

prevent

Enforces access control decisions on file system resources so that even malformed paths cannot reach unauthorized directories.

detect

Monitors file system access patterns and anomalies that would result from successful path traversal attempts.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

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.

detects

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.
