- CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H
Description
### Impact undici's `RetryHandler` can leave a response body pending indefinitely. When a retried request receives a non-retryable response after a truncated one, the original `response.body` held by the application is never settled, so reads such as `response.body.text()` hang and `bodyTimeout` does not fire. A malicious server can repeat this to accumulate pending promises and streams, leading to denial of service. ### Patches Patched in undici v7.29.1 and v8.10.2. ### Workarounds Impose an independent request deadline and destroy the response body when it expires. `bodyTimeout` alone does not prevent this.
