Ansible Insertion of Sensitive Information into Log File vulnerability

CVE-2017-7550GHSA-588w-w6mv-3cw5

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (ansible 2.4.1.0, 2.3.3.0), 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.

A flaw was found in the way Ansible (2.3.x before 2.3.3, and 2.4.x before 2.4.1) passed certain parameters to the jenkinsplugin module. Remote attackers could use this flaw to expose sensitive information from a remote host's logs. This flaw was fixed by not allowing passwords to be specified in the "params" argument, and noting this in the module documentation.

# Patch Next advisory brief: CVE-2017-7550

Advisory: Ansible Insertion of Sensitive Information into Log File vulnerability
IDs: CVE-2017-7550, GHSA-588w-w6mv-3cw5
Record: https://patchnext.com/advisories/cve-2017-7550 (revision 3, source checked 26 Oct 2026, 13:16 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: ansible 2.4.1.0, 2.3.3.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI ansible: affected >= 2.4.0.0, < 2.4.1.0; >= 2.3.0.0, < 2.3.3.0; fixed in 2.3.3.0, 2.4.1.0

## Suggested inspection (read-only)
- `python -m pip show ansible`: 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 ansible.
- 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?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
