Information Exposure Affecting ansible-core package, versions [2.19.0b1,2.22.0b2)
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

Upgrade ansible-core to version 2.22.0b2 or higher.
Overview
ansible-core is an a radically simple IT automation system. It handles configuration management, application deployment, cloud provisioning, ad-hoc task execution, network automation, and multi-node orchestration. Ansible makes complex changes like zero-downtime rolling updates with load balancers easy.
Affected versions of this package are vulnerable to Information Exposure via the PRESERVE allow-list in lib/ansible/_internal/_task.py. When a task marked no_log: true fails, the default stdout callback prints its retained exception text, which can include secret argument values, variable-file source snippets, or full fail/assert messages. This exposes sensitive data in terminal output, CI logs, and automation logs.
Notes
- On the exception-generation step, a templating error prints the failing line and the two preceding lines of the variables file, so secrets in nearby lines of a file such as
-e @secrets.ymlcan leak even if they are not the failing value.
