Name of the Vulnerable Software and Affected Versions @backstage/backend-common versions prior to 0.21.1 @backstage/backend-common versions prior to 0.20.2 @backstage/backend-common versions prior to 0.19.10

Description The issue concerns the @backstage/backend-common library, where paths checks with the resolveSafeChildPath utility were not exhaustive enough, leading to a risk of path traversal vulnerabilities if symlinks can be injected by attackers.

Recommendations For versions prior to 0.21.1, update to version 0.21.1 or later. For versions prior to 0.20.2, update to version 0.20.2 or later. For versions prior to 0.19.10, update to version 0.19.10 or later. As a temporary workaround, consider restricting the use of the resolveSafeChildPath utility until a patch is applied.
