Hi,

The following vulnerability was published for undertow.

CVE-2024-7885[0]:
| A vulnerability was found in Undertow where the
| ProxyProtocolReadListener reuses the same StringBuilder instance
| across multiple requests. This issue occurs when the
| parseProxyProtocolV1 method processes multiple requests on the same
| HTTP connection. As a result, different requests may share the same
| StringBuilder instance, potentially leading to information leakage
| between requests or responses. In some cases, a value from a
| previous request or response may be erroneously reused, which could
| lead to unintended data exposure. This issue primarily results in
| errors and connection termination but creates a risk of data leakage
| in multi-request environments.
