CVE-2026-40024 — Sleuthkit The Sleuth Kit security vulnerability

High CVSS 8.4

The Sleuth Kit through 4.14.0 contains a path traversal vulnerability in tsk_recover that allows an attacker to write files to arbitrary locations outside the intended recovery directory via crafted filenames or directory paths with path traversal sequences in a filesystem image. An attacker can craft a malicious filesystem image with embedded /../ sequences in filenames that, when processed by tsk_recover, writes files outside the output directory, potentially achieving code execution by overwriting shell configuration or cron entries.

Path traversal, unsafe upload, and file handling

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
  • Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
  • Review canonicalization and containment checks across supported operating systems and storage backends.

Remediate safely

  • Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
  • Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
  • Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
