description

openapi-typescript-codegen through version 0.31.0 can produce generated clients containing attacker-controlled JavaScript. An attacker must be able to supply or modify the OpenAPI document used for generation; the code may run when the generated client is imported or invoked.

mitigation

Do not generate clients from untrusted or user-modifiable OpenAPI documents, and restrict who can alter specifications in the generation pipeline. Review and regenerate affected clients after validating their source specifications; no fixed version is recorded.
