CVE-2026-96755 Details
Description
orval versions 8.14.0 through 8.28.1 contain a code injection vulnerability in the @orval/effect generator that converts OpenAPI schema defaults into template literals. Attackers can inject arbitrary JavaScript expressions via schema defaults containing ${...} syntax, which are executed at module scope when the generated code is built or imported.
A code injection vulnerability has been identified in the Orval tool, specifically in versions 8.14.0 through 8.28.1. This vulnerability resides within the '@orval/effect' generator, which processes OpenAPI schema defaults. The issue allows attackers to inject arbitrary JavaScript expressions into schema defaults using the '${...}' syntax. When the generated code is built or imported, these expressions are executed at the module scope, potentially leading to unauthorized code execution.
Users can upgrade to Orval version 8.29.0 or later, where this vulnerability has been patched.
