Low severity GitHub Reviewed Published Apr 18, 2026 to the GitHub Advisory Database • Updated Apr 22, 2026

Package

pip apache-airflow-core (pip)

Affected versions

>= 3.0.0, < 3.2.0

Patched versions

3.2.0

Description

Secrets in Variables saved as JSON dictionaries were not properly redacted - in case the variables were retrieved by the user the secrets stored as nested fields were not masked.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
