CVE-2026-63225: Path Traversal (CVSS 4.4)

Description

Redocly CLI makes OpenAPI validation, linting, and documentation workflows easier. Prior to @redocly/cli 2.33.2, the split command constructs output paths under --outDir from untrusted OpenAPI or AsyncAPI component names and x-codeSamples lang values without verifying that the resolved target remains inside the selected directory. A description containing literal ../ traversal segments in those fields can cause the split command to place or overwrite files outside --outDir. Component data remains constrained to YAML or JSON, and code-sample filenames remain based on the HTTP method, so this is not an unrestricted arbitrary-content file write. This issue is fixed in @redocly/cli version 2.33.2.
