Short explanation

A vulnerability in Red Hat ansible-core causes sensitive information to leak into terminal output, CI logs, and automation logs when tasks marked with no_log: true fail.

Why does it matter?

Sensitive data that operators explicitly intended to hide can be exposed through error messages and exception handling.

What should be done?

  • Follow the vendor security advisories
  • Apply relevant updates
  • Review automation logs
Chain of evidence and sources2 verified claims

ansible-core 2.19 sürümünde tanıtılan bir regresyon nedeniyle no_log: true görevleri hata verdiğinde istisna alanı korunur.

Hassas veriler terminal çıktısına, CI günlüklerine ve otomasyon loglarına sızabilir.

Show the technical text from the sources

A flaw was found in ansible-core. When a task marked `no_log: true` fails, the task result is censored before being emitted, but the `exception` field is retained because it is present in the PRESERVE allow-list in lib/ansible/_internal/_task.py, and the default stdout callback prints it through CallbackBase._handle_exception. As a result, sensitive values the operator explicitly asked to hide can be disclosed: module argument-validation errors echo the argument value, templating errors print an Origin source snippet (the failing line plus the two preceding lines of the variables file, exposing neighbouring secrets from an -e @secrets.yml file), and fail/assert messages are printed in full. Secret material supplied as extra variables or variables files can therefore leak to terminal output, CI logs, and the stdout logs of any automation wrapping ansible-playbook, even though every task touching the secrets is marked no_log: true. This is a regression introduced with the ansible-core 2.19 data-tagging/templating rework; the behaviour does not occur on 2.16, where the error text is correctly censored.

Patch and Remediation Guide

Solution & Remediation Advisory

Patch status unknown

İncelenen resmî kaynaklarda yama durumu doğrulanamadı. Bu sonuç “yama yok” anlamına gelmez.

Confirm the affected product and version against the source evidence above.
Restrict access to internet-facing services and apply network segmentation.
Until a patch is confirmed, follow the vendor advisory; do not read an unknown status as “no patch”.
Monitor server logs and network endpoints for signs of anomalous execution.
