Summary
Redocly CLI: Path traversal when using `split` command
Details

Impact

An OpenAPI or AsyncAPI description could make the split command write files outside the chosen output directory, on the machine of anyone who runs split against it. The write is constrained rather than a free file-write primitive: component data is emitted only as YAML/JSON, and code-sample files are named after the HTTP method, so an attacker can place or overwrite files at an unintended path but has limited control over their name and contents.

Patches

Fixed in @redocly/cli v2.33.2.

Workarounds

Do not run the split command on API descriptions from untrusted or unreviewed sources.

To detect an exploit attempt, inspect the description's component names and x-codeSamples lang values for a literal ../ — neither legitimately contains path segments.
