CVE intelligence and bounded remediation

CVE-2025-64346 — archives is a Go library for extracting archives (tar, zip, etc.)

Medium CVSS 6

archives is a Go library for extracting archives (tar, zip, etc.). Version 1.0.0 does not prevent a malicious user to feed a specially crafted archive to the library causing RCE, modification of files or other malignancies in the context of whatever the user is running this library as, through the program that imports it. Severity depends on user permissions, environment and how arbitrary archives are passed. This issue is fixed in version 1.0.1.

Matched remediation archetype

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.
