EPSS

• CVE-2019-14867: 7.41% estimated exploitation activity in the next 30 days; percentile 94.45 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

A flaw was found in IPA, all 4.6.x versions before 4.6.7, all 4.7.x versions before 4.7.4 and all 4.8.x versions before 4.8.3, in the way the internal function berscanf() was used in some components of the IPA server, which parsed kerberos key data. An unauthenticated attacker who could trigger parsing of the krb principal key could cause the IPA server to crash or in some conditions, cause arbitrary code to be executed on the server hosting the IPA server.

# Patch Next advisory brief: CVE-2019-14867

Advisory: Code injection in FreeIPA
IDs: CVE-2019-14867, GHSA-7hpj-hfcr-5qwm
Record: https://patchnext.com/advisories/cve-2019-14867 (revision 3, source checked 26 Oct 2026, 13:17 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: freeipa 4.8.3, 4.7.4, 4.6.7; ipa 4.8.3, 4.7.4, 4.6.7. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI freeipa: affected >= 4.6.2, < 4.6.7; >= 4.7.0, < 4.7.4; >= 4.8.0, < 4.8.3; fixed in 4.8.3, 4.6.7, 4.7.4
- PyPI ipa: affected >= 4.6.2, < 4.6.7; >= 4.7.0, < 4.7.4; >= 4.8.0, < 4.8.3; fixed in 4.8.3, 4.6.7, 4.7.4

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