Security readout for executives and security teams

This is a stored cross-site scripting issue in Plone. A lower-privileged Contributor could place script content in a folder description, and an Editor could be exposed when viewing folder contents. Business risk is mainly account/session abuse or unauthorized actions inside the CMS, depending on Editor privileges. Exposure is likely limited to Plone 5.0 through 5.2.4 installations where Contributors can create folders and Editors use the folder contents view. Treat as a moderate-priority CMS issue. Prioritize public or multi-user Plone sites, especially where external contributors can create content and internal Editors have privileged CMS access. Mitigation focus: Review Plone's 20210518 security hotfix guidance.; Apply the vendor hotfix where applicable.; Check current Plone guidance for supported upgrade paths..
