Detailsinfo

A vulnerability was found in orval-labs orval up to 7.17.x. It has been rated as critical. This issue affects an unknown code of the component OpenAPI. The manipulation of the argument summary with an unknown input leads to a command injection vulnerability. Using CWE to declare the problem leads to CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

orval generates type-safe JS clients (TypeScript) from any valid OpenAPI v3 or Swagger v2 specification. Prior to 7.18.0, the MCP server generation logic relies on string manipulation that incorporates the summary field from the OpenAPI specification without proper validation or escaping. This allows an attacker to "break out" of the string literal and inject arbitrary code. This vulnerability is fixed in 7.18.0.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-22785 since 01/09/2026. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1202 for this issue.

Upgrading to version 7.18.0 eliminates this vulnerability. Applying the patch 80b5fe73b94f120a3a5561952d6d4b0f8d7e928d is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
