CyberRota Analysis
AI-GeneratedThe @backstage/plugin-techdocs-node package in Backstage versions prior to 1.14.6 and from 1.15.0 to 1.15.4 is vulnerable due to insufficient validation of mkdocs.yml files submitted by authenticated users, potentially allowing for unsafe Python YAML tags and configurations to lead to unintended code execution. This vulnerability could compromise the files, credentials, and network access associated with the TechDocs backend or build container. Organizations using affected versions should prioritize updating to versions 1.14.6 or 1.15.4 to mitigate this high-severity risk.

Original NVD Description
Backstage is an open framework for building developer portals. Prior to 1.14.6 and from 1.15.0 until 1.15.4, the @backstage/plugin-techdocs-node package insufficiently validates mkdocs.yml supplied by an authenticated user who can register or modify a TechDocs source. Unsafe Python YAML tags, markdown_extensions names and configuration, theme options, and extra_templates values can reach the documentation generator and cause unintended code execution. The resulting impact is limited to the files, credentials, network access, and other resources available to the TechDocs backend or build container. This issue is fixed in versions 1.14.6 and 1.15.4.
