Arbitrary code execution via comment breakout
Published Jan 30, 2026 · Updated Jan 30, 2026
Code injection in Orval 7.19.0 and later before 7.21.0 and 8.0.0 and later before 8.2.0 allows remote attackers to execute arbitrary JavaScript. The x-enumDescriptions path emits attacker-controlled descriptions inside JavaScript comments, while jsStringEscape leaves * and / unchanged, so */ closes the comment and injected code enters generated files. Exploitation requires processing an attacker-controlled OpenAPI specification; the injected JavaScript runs when the generated client is consumed.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=>= 7.19.0, < 7.21.0
- Affected versionversion=>= 8.0.0, < 8.2.0
