Security readout for executives and security teams
Plain-English summary
CVE-2020-24898 affects the Table Filter and Charts for Confluence Server app before version 5.3.26. A logged-in user could make the app fetch a URL through the Table from CSV macro, creating server-side request forgery risk. The main business concern is exposure of internal resources reachable from Confluence.
Executive priority
Treat this as high priority for Confluence Server environments using the affected app, especially internet-facing or broadly accessible collaboration systems. The issue can expose internal services through Confluence’s network position.
Technical view
The issue is SSRF in the Table from CSV macro URL parameter in Table Filter and Charts for Confluence Server versions before 5.3.26. CVSS 3.1 is 7.6 high, with network attack vector, low complexity, low privileges required, no user interaction, high confidentiality impact, and low integrity and availability impact.
Likely exposure
Exposure is limited to Confluence Server deployments with the Stiltsoft Table Filter and Charts app installed below 5.3.26. Risk is higher where many authenticated users can create or edit pages and use macros.
Exploitation context
The provided sources do not report active exploitation, and the CVE is not listed as KEV in the supplied bundle. Exploitation requires authenticated access, but no user interaction is required after the attacker has privileges.
Researcher notes
The CVE record provides a concise affected condition but limited operational detail. Validation should focus on version confirmation, macro availability, and Confluence’s outbound request history. Do not assume affected products beyond the named Confluence Server app.
Mitigation direction
- Upgrade Table Filter and Charts for Confluence Server to 5.3.26 or later.
- Review Stiltsoft advisory VD-1 for any environment-specific vendor guidance.
- Prioritize Confluence instances with broad page editing or macro permissions.
- Track the change through normal Confluence plugin update and rollback procedures.
Validation and detection
- Inventory Confluence Server apps and confirm the installed Table Filter and Charts version.
- Identify spaces where authenticated users can create pages or use the Table from CSV macro.
- Review Confluence and proxy logs for unusual outbound requests from Confluence servers.
- Confirm remediation by rechecking the app version after maintenance.
