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
The Table Filter and Charts for Confluence Server app before 5.3.26 (for Atlassian Confluence) allows SSRF via the "Table from CSV" macro (URL parameter).

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The Table Filter and Charts for Confluence Server app before version 5.3.26 contains a Server-Side Request Forgery (SSRF) vulnerability in the 'Table from CSV' macro. The macro accepts a URL parameter to import CSV data without proper validation, allowing attackers to induce the server to make arbitrary requests to internal resources or external systems.

MitigationUpgrade the Table Filter and Charts for Confluence app to version 5.3.26 or later. If immediate upgrading is not feasible, restrict network access to the Confluence instance and consider temporarily disabling the Table from CSV macro.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed version of Table Filter and Charts
    Navigate to Confluence Administration > Manage apps > Table Filter and Charts for Confluence. Check the version number displayed in the app details.
    Affected if The version shown is less than 5.3.26 (e.g., 5.3.25, 5.3.0, etc.)
  2. Verify Table from CSV macro is accessible
    In Confluence, attempt to create or edit a page and check if the 'Table from CSV' macro is available in the macro browser. Look for it under the Table Filter category or search for 'CSV'.
    Affected if The macro is listed and available for use in page editor
  3. Review recent Confluence access logs for suspicious URL patterns
    Examine Confluence access logs (atlasian-confluence-access.log) for requests containing URL parameters that point to internal IP addresses (e.g., 127.0.0.1, 10.x.x.x, 192.168.x.x), cloud metadata endpoints (169.254.169.254), or unusual external domains.
    Affected if Logs show requests from the Table from CSV macro to internal resources or unexpected external URLs
  4. Check for unexpected outbound connections
    Review Confluence server network connections or firewall logs for outbound HTTP/HTTPS requests originating from the Confluence application, particularly to internal services or non-standard ports.
    Affected if The Confluence server has made outbound requests to internal network resources that were not initiated by legitimate user actions

A user is affected if their Table Filter and Charts for Confluence app version is below 5.3.26 AND the Table from CSV macro is accessible and being used.
