Résumé
Backstage: Improper input validation in Confluence to Markdown scaffolder module
Détails de l’avis
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

Workarounds
If unable to update immediately:

- Review Confluence page content before running scaffolder templates against untrusted pages.
