Title

Redocly CLI: Arbitrary code execution via Arazzo `$faker` expression using `respect`

Summary

Redocly CLI makes OpenAPI validation, linting, and documentation workflows easier. Prior to version 2.33.0 of @redocly/respect-core and @redocly/cli, the respect command dynamically evaluates $faker runtime expressions in Arazzo descriptions. A crafted expression can traverse constructor, prototype, or __proto__ properties in packages/respect-core/src/modules/context-parser/get-value-from-context.ts, reach the JavaScript Function constructor, and execute arbitrary code when a user processes an untrusted description. The executed code runs with the privileges of the CLI process and can execute shell commands or read CI secrets. Users processing only trusted, self-authored workflows are not affected. This issue is fixed in @redocly/respect-core and @redocly/cli version 2.33.0.

Severity

7.8 (High)
