AI-suggested
Upgrade orval to version 8.28.0 or later where this vulnerability is fixed. Patch status is confirmed by the versioning information indicating the fix in 8.28.0. Until upgrading, avoid processing untrusted OpenAPI schemas that could contain malicious property names.
Description
orval @orval/core before 8.28.0 contains a code injection vulnerability in the form-data serializer that fails to escape multipart property names in generated template literals. Attackers can inject ${...} expressions into OpenAPI schema property names that execute as live interpolation when the generated client builds FormData bodies with consumer process privileges.
