Backstage is an open framework for building developer portals. Prior to 1.14.6, the @backstage/plugin-techdocs-node package is affected by remote code execution via crafted markdown_extensions in techdocs mkdocs.yml. An authenticated user who can register catalog entities can provide a crafted mkdocs.yml causing arbitrary OS command execution on the TechDocs build host when the docs are built. This issue is fixed in versions 1.14.6 and 1.15.4.

Affected: npm: @backstage/plugin-techdocs-node

### Impact

An authenticated user who can register catalog entities can provide a crafted `mkdocs.yml` causing arbitrary OS command execution on the TechDocs build host when the docs are built.

### Patches

Patched in `@backstage/plugin-techdocs-node`, version `1.15.4`.

### Workarounds

If you cannot upgrade immediately:

- Switch to `techdocs.builder: external` to isolate TechDocs builds in a container. - Restrict who can register catalog entities with TechDocs annotations. - Audit existing catalog entities for suspicious `markdown_extensions` values in their `mkdocs.yml` files.
