Summary

Backstage: Improper input validation in Confluence to Markdown scaffolder module

Details

Impact

Insufficient input validation in the Confluence to Markdown scaffolder module could allow an attacker to influence file write operations during template execution. Exploitation requires a Backstage user to run a template that processes attacker-influenced Confluence content.

Patches

Patched in @backstage/plugin-scaffolder-backend-module-confluence-to-markdown version 0.3.25

Workarounds

If unable to update immediately:

Restrict Confluence edit access to trusted users.
Review Confluence page content before running scaffolder templates against untrusted pages.
