Apache Airflow Providers Http has Unsafe Pickle Deserializatio leading to RCE via HttpOperator

High severity GitHub Reviewed Published Mar 9, 2026 to the GitHub Advisory Database • Updated Mar 10, 2026

Package

pip apache-airflow-providers-http (pip)

Affected versions

< 6.0.0

Patched versions

6.0.0

Description

A user with access to the DB could craft a database entry that would result in executing code on Triggerer - which gives anyone who have access to DB the same permissions as Dag Author. Since direct DB access is not usual and recommended for Airflow, the likelihood of it making any damage is low.

Users should upgrade to version 6.0.0 of the provider to avoid even that risk.

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.
