How to Fix CVE-2011-4356

To remediate this vulnerability, upgrade all affected Celery dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

celery fixed: 2.2.8 
pip install celery>=2.2.8
celery fixed: 2.3.4 
pip install celery>=2.3.4
celery fixed: 2.4.4 
pip install celery>=2.4.4
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show celery

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2011-4356, inspect your installed packages using pip:

pip show celery

Analyze the terminal output to locate any version of Celery in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.2.8), your application is affected.

Note: The pip show celery command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-269: Improper Privilege Management, where the product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. In Celery, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Celery 2.1 and 2.2 before 2.2.8, 2.3 before 2.3.4, and 2.4 before 2.4.4 changes the effective id but not the real id during processing of the --uid and --gid arguments to celerybeat, celeryd_detach, celeryd-multi, and celeryev, which allows local users to gain privileges via vectors involving crafted code that is executed by the worker process.
