| Title | redocly redocly-cli 2.32.2 Path Traversal |
|---|
| Description | Output file paths are built directly from untrusted specification content (component names, and x-codeSamples lang values) with no traversal guard, so a crafted name writes files outside the output directory with attacker controlled content.
redocly split builds output paths directly from untrusted specification content with no traversal guard. A component key (components.<type>.<key>) is used raw in getFileNamePath (packages/cli/src/commands/split/utils/iterate-components.ts:70 and get-file-name-path.ts), so a key containing ../ escapes the output directory and writes a YAML or JSON file there. A second vector is x-codeSamples[].lang, where escapeLanguageName replaces only the first / (no global flag) in packages/cli/src/utils/miscellaneous.ts:150, allowing traversal and writing fully raw attacker content.
