CVE intelligence and bounded remediation

CVE-2023-30620 — mindsdb is a Machine Learning platform to help developers build AI solutions

High CVSS 7.5

mindsdb is a Machine Learning platform to help developers build AI solutions. In affected versions an unsafe extraction is being performed using `tarfile.extractall()` from a remotely retrieved tarball. Which may lead to the writing of the extracted files to an unintended location. Sometimes, the vulnerability is called a TarSlip or a ZipSlip variant. An attacker may leverage this vulnerability to overwrite any local file which the server process has access to. There is no risk of file exposure with this vulnerability. This issue has been addressed in release `23.2.1.0 `. Users are advised to upgrade. There are no known workarounds for this vulnerability.

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.
