Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited

Attackers can inject malicious HTML or JavaScript payloads through Markdown markup submitted to the 'Table from CSV' macro, which is then executed when other users view the rendered content.

MitigationUpgrade the Table Filter and Charts for Confluence app to version 5.3.25 or later through the Atlassian Marketplace or Unified Plugin Management (UPM), and verify that the Table from CSV macro functions correctly post-upgrade.
