Comment 1 Lumír Balhar 2026-06-14 14:50:06 UTC 
fast-uri is bundled as a dependency of ajv (JSON Schema validator) and used exclusively for URI format validation in settings schemas. JupyterLab makes no security decisions (access control, routing, allowlists) based on URI normalization from fast-uri. No exploitable path exists.
