A vulnerability was determined in vercel ai up to 3.0.97. The impacted element is the function createJsonResponseHandler/createJsonErrorResponseHandler of the file packages/provider-utils/src/response-handler.ts of the component provider-utils. This manipulation causes resource consumption. The attack may be initiated remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.

Affected: npm: @ai-sdk/provider-utils

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.
