Summary
Backstage: Improper validation of TechDocs MkDocs configuration
Details

Impact

An attacker who can provide configuration to a TechDocs build may execute code in the generator runtime. Impact is greatest when documentation generation runs with backend credentials or host access.

Patches

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

Workarounds

Use external TechDocs generation in an isolated environment without sensitive credentials or host access. Restrict and review changes to documentation configuration before generation.
