SaltStack Salt is vulnerable Arbitrary Directory Access

CVE-2020-11652GHSA-vp49-2g4r-m3x3

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (salt 3000.2, 2019.2.4), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

An issue was discovered in SaltStack Salt before 2019.2.4 and 3000 before 3000.2. The salt-master process ClearFuncs class allows access to some methods that improperly sanitize paths. These methods allow arbitrary directory access to authenticated users.

# Patch Next advisory brief: CVE-2020-11652

Advisory: SaltStack Salt is vulnerable Arbitrary Directory Access
IDs: CVE-2020-11652, GHSA-vp49-2g4r-m3x3
Record: https://patchnext.com/advisories/cve-2020-11652 (revision 4, source checked 26 Oct 2026, 13:35 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.1)
Exploitation: confirmed: listed in the CISA Known Exploited Vulnerabilities catalog.
Vendor response: Vendor fix available; fixed versions by package: salt 3000.2, 2019.2.4. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI salt: affected < 2019.2.4; >= 3000, < 3000.2; fixed in 3000.2, 2019.2.4

## Suggested inspection (read-only)
- `python -m pip show salt`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on salt.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Mark the work resolved only after the fixed version is verified in production.
