Security readout for executives and security teams
Plain-English summary
CVE-2026-22785 affects orval, a tool that generates TypeScript clients from OpenAPI or Swagger definitions. Before version 7.18.0, malicious content in an API specification’s summary field could be inserted into generated MCP server code. Organizations using orval in development or CI/CD should treat untrusted API specs as a serious supply-chain risk.
Executive priority
Prioritize remediation for teams using orval in automated builds or accepting third-party API specifications. The business risk is malicious code entering generated software through a trusted development tool.
Technical view
The vulnerable MCP server generation logic used string manipulation without properly validating or escaping the OpenAPI summary field. An attacker controlling a consumed specification could break out of a string literal and inject arbitrary code into generated output. The issue is listed as CWE-77 and fixed in orval 7.18.0.
Likely exposure
Exposure is most likely in developer workstations, build systems, or CI pipelines using orval versions earlier than 7.18.0 to generate MCP server code from OpenAPI v3 or Swagger v2 specifications, especially externally supplied or partner-provided specs.
Exploitation context
The CVE record states network attack complexity is low and no privileges or user interaction are required in the CVSS model. However, the provided sources do not state active exploitation, and the CVE is not marked in KEV.
Researcher notes
The public record identifies affected versions as orval before 7.18.0 and points to a fixing commit. Evidence is sufficient for exposure assessment, but the provided sources do not include proof of exploitation or detailed operational indicators.
Mitigation direction
- Upgrade orval to version 7.18.0 or later.
- Avoid generating MCP server code from untrusted specifications until upgraded.
- Review provenance of OpenAPI and Swagger files used in builds.
- Check the GitHub advisory for any additional vendor guidance.
Validation and detection
- Inventory projects and CI jobs using orval.
- Confirm installed orval versions are 7.18.0 or later.
- Identify workflows generating MCP server output.
- Review whether consumed API specs come from external or untrusted sources.

Improper Neutralization of Special Elements used in a Command ('Command Injection')
Improper Neutralization of Special Elements used in a Command ('Command Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
