Redocly CLI: Path traversal when using `split` command
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| npm | @redocly/cli | < 1.34.17 | 1.34.17 |
| npm | @redocly/cli | >= 2.0.0, < 2.33.2 | 2.33.2 |
Details
As written in the advisory (Markdown source, shown as plain text).
### 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.
