QID 982079: Nodejs (npm) Security Update for @backstage/techdocs-common (GHSA-pwhf-39xg-4rxw)

Security update has been released for @backstage/techdocs-common to fix the vulnerability.

Note: The preceding description block is extracted directly from the security advisory. Using automation, we have attempted to clean and format it as much as possible without introducing additional issues.

A malicious internal actor is able to upload documentation content with malicious scripts. These scripts would normally be sanitized by the TechDocs frontend, but by tricking a user to visit the content via the TechDocs API, the content sanitazion will be bypassed. If the TechDocs API is hosted on the same origin as the Backstage app or other backend plugins, this may give access to sensitive data.

The ability to upload malicious content may be limited by internal code review processes, unless the chosen TechDocs deployment method is to use an object store and the actor has access to upload files directly to that store.

CVSS V3 rated as Critical - 8.1 severity.

CVSS V2 rated as Medium - 5.8 severity.

Solution

The vulnerability is patched in the `0.6.4` release of `@backstage/techdocs-common`.
