How to Fix CVE-2017-1000483

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

Plone fixed: 4.3.16 
pip install Plone>=4.3.16
Plone fixed: 5.1.0 
pip install Plone>=5.1.0
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 Plone

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2017-1000483, inspect your installed packages using pip:

pip show Plone

Analyze the terminal output to locate any version of Plone in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.3.16), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
