Severity
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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
