    CVE-2026-33331 (GCVE-0-2026-33331)

    Title
    oRPC: Stored XSS in OpenAPI Reference Plugin via unescaped JSON.stringify
    Summary
    oRPC is an tool that helps build APIs that are end-to-end type-safe and adhere to OpenAPI standards. Prior to version 1.13.9, a stored cross-site scripting (XSS) vulnerability exists in the OpenAPI documentation generation of orpc. If an attacker can control any field within the OpenAPI specification (such as info.description), they can break out of the JSON context and execute arbitrary JavaScript when a user views the generated API documentation. This issue has been patched in version 1.13.9.

    CVE-2026-28794 (GCVE-0-2026-28794)

    Vulnerability from cvelistv5 – Published: 2026-03-06 05:02 – Updated: 2026-03-09 19:53

    Title
    oRPC: Prototype Pollution in `@orpc/client` via `StandardRPCJsonSerializer` Deserialization
    Summary
    oRPC is an tool that helps build APIs that are end-to-end type-safe and adhere to OpenAPI standards. Prior to version 1.13.6, a prototype pollution vulnerability exists in the RPC JSON deserializer of the @orpc/client package. The vulnerability allows unauthenticated, remote attackers to inject arbitrary properties into the global Object.prototype. Because this pollution persists for the lifetime of the Node.js process and affects all objects, it can lead to severe security breaches, including authentication bypass, denial of service, and potentially Remote Code Execution. This issue has been patched in version 1.13.6.
