AI risk analysis
- Summary
- The flaw allows code injection by failing to escape OpenAPI path values, enabling arbitrary JavaScript code execution.
- Exploitability
- Exploitation is relatively straightforward with preconditions of an attacker-controlled OpenAPI document containing specific path segments.
- Blast radius
- If exploited, this could lead to full system compromise, as arbitrary code execution can be achieved.
- Detection
- No reliable host or network indicator is derivable from the published description.
- Prioritized remediation
- Upgrade to orval version 8.29.0 or later.

NVD description
orval versions before 8.29.0 contain a code injection vulnerability in the @orval/hono generator that fails to escape OpenAPI path values in single-quoted route literals. Attackers can craft an OpenAPI document with an apostrophe in a static path segment to inject arbitrary JavaScript code that executes when the generated TypeScript module is imported.
