Name of the Vulnerable Software and Affected Versions @backstage/plugin-scaffolder-backend-module-confluence-to-markdown versions prior to 0.3.25

Description Improper repository path validation in a scaffolder backend module allows an authenticated user who can execute an affected template and control its repository file location to cause generated content to be written outside the task workspace, within locations writable by the Backstage backend process.
