Description
Backstage is an open framework for building developer portals. Prior to 0.3.25, the @backstage/plugin-scaffolder-backend-module-confluence-to-markdown package is affected by improper input validation in confluence to markdown scaffolder module. 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. This issue is fixed in version 0.3.25.
Affected configurations
• linuxfoundation backstage\/plugin-scaffolder-backend-module-confluence-to-markdown (< 0.3.25)
• linuxfoundation backstage (< 1.54.6)
