    Summary: @ai-sdk/provider-utils has an Uncontrolled Resource Consumption issue

    Details: Versions of `@ai-sdk/provider-utils` before 3.0.28, from 4.0.0 before 4.0.33, and from 5.0.0 before 5.0.1 are vulnerable to uncontrolled resource consumption. The `createJsonResponseHandler`, `createJsonErrorResponseHandler`, and `createStatusCodeErrorResponseHandler` functions in `packages/provider-utils/src/response-handler.ts` read response bodies without a shared size limit, allowing a remote attacker with low privileges to cause excessive memory consumption. The exploit has been publicly disclosed and may be utilized.
