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.
