CVE-2026-96754: Orval-Labs Orval

Critical severity, CVSS 9.8. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Orval-Labs Orval: before 8.29.0 (fixed in 8.29.0)
