pip install manila>=7.4.1
manila fixed: 8.1.1 
pip install manila>=8.1.1
manila fixed: 9.1.1 
pip install manila>=9.1.1
Verify Direct and Transitive Dependencies

pip show manila

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2020-9543, inspect your installed packages using pip:

pip show manila

Analyze the terminal output to locate any version of Manila in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 7.4.1), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-276: Incorrect Default Permissions, where during installation, installed file permissions are set to allow anyone to modify those files. In Manila, 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

OpenStack Manila <7.4.1, >=8.0.0 <8.1.1, and >=9.0.0 <9.1.1 allows attackers to view, update, delete, or share resources that do not belong to them, because of a context-free lookup of a UUID. Attackers may also create resources, such as shared file systems and groups of shares on such share networks.
