Summary

CVE-2025-32802 is a medium-severity External Control of File Name or Path (CWE-73) vulnerability. Its CVSS base score is 6.1 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked at the 9th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-6 (Least Privilege) and SC-4 (Information in Shared System Resources) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

AC-6 reduces the set of actors that can reach an insecurely created temp file by limiting privileges on the containing directory.

SC-4 stops unintended information exposure through shared resources such as world-writable temp directories or files.

Input validation directly rejects or sanitizes untrusted path strings before they reach filesystem operations.

Enforces authorization checks on the actual resource accessed, blocking unauthorized files even when a malicious path is supplied.

Secure SDLC practices include input validation and path sanitization that eliminate this weakness.

Least-privilege file authorization directly limits damage from externally controlled paths.

finds

Security testing can detect path-traversal issues but does not itself implement preventive controls.

prevents

Secure development lifecycle mandates input validation and path-handling controls that directly prevent external file/path manipulation.

prevents

Application security requirements explicitly call for controls against untrusted input influencing file operations.

prevents

Secure architecture principles discourage unsafe path construction but do not prescribe concrete file-name controls.

prevents

Secure coding standards require canonicalization, allow-listing, and bounds checks on file paths, directly eliminating CWE-73.

mitigates

Information access restriction limits which files can be reached, indirectly reducing impact of path manipulation.
