Overview

@backstage/plugin-techdocs-node is a Common node.js functionalities for TechDocs, to be shared between techdocs-backend plugin and techdocs-cli

Affected versions of this package are vulnerable to Interpretation Conflict via the extra_templates key in MkDocs configuration handling in helpers.ts, where an attacker with the ability to supply a MkDocs configuration file can inject arbitrary Jinja2 templates that are rendered server-side, leading to high confidentiality impact and partial integrity and availability impact on the host system. The extra_templates key was included in the ALLOWED_MKDOCS_KEYS allowlist, permitting user-controlled template paths to be passed through to MkDocs without restriction.
