Backstage: Improper validation of TechDocs MkDocs configuration
### 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.
