How to Fix CVE-2017-1000482

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

Products.CMFPlone fixed: 4.3.17 
pip install Products.CMFPlone>=4.3.17
Products.CMFPlone fixed: 5.0.10 
pip install Products.CMFPlone>=5.0.10
Products.CMFPlone fixed: 5.1.0 
pip install Products.CMFPlone>=5.1.0
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 Products.CMFPlone

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2017-1000482, inspect your installed packages using pip:

pip show Products.CMFPlone

Analyze the terminal output to locate any version of Products.CMFPlone in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.3.17), your application is affected.

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

Technical Details
