CVE-2026-24132

CVE-2026-24132 affects Orval’s mock generation path in @orval/mock. Untrusted OpenAPI specs can inject arbitrary TypeScript/JavaScript into generated mock files through the const values on schema properties, which are interpolated into the mock scalar generator without proper escaping. This can l...

GHSA-F456-RF33-4626 Orval Mock Generation Code Injection via const

I am reporting a code injection vulnerability in Orval’s mock generation pipeline affecting @orval/mock in both the 7.x and 8.x series. This issue is related in impact to the previously reported enum x-enumDescriptions https://github.com/advisories/GHSA-h526-wf6g-67jv, but it affects a different...

Arbitrary Code Execution

Orval is vulnerable to Arbitrary Code Execution. The vulnerability is due to unsanitized embedding of untrusted OpenAPI fields, where attacker-controlled values in the x-enumDescriptions field are injected without proper escaping during enum generation, resulting in executable JavaScript/TypeScri...

Orval generates type-safe JS clients TypeScript from any valid OpenAPI v3 or Swagger v2 specification. Versions 7.19.0 and below and 8.0.0-rc.0 through 8.0.2 allow untrusted OpenAPI specifications to inject arbitrary TypeScript/JavaScript into generated mock files via the const keyword on schema...

Arbitrary Command Injection

@orval/mcp is vulnerable to Arbitrary Command Injection. The vulnerability is due to improper validation and escaping of the OpenAPI specification summary field during MCP server generation, which allows an attacker to break out of string literals and inject arbitrary code...

Arbitrary Command Injection

Overview Affected versions of this package are vulnerable to Arbitrary Command Injection via improper handling of the summary field during server generation logic. An attacker can execute arbitrary code by injecting malicious input into the OpenAPI specification, which is then incorporated withou...
