Description

This security bulletin contains information about 1 security vulnerability.


1) Information disclosure (CVE-ID: CVE-2024-7885)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to insecure sharing of resources where the ProxyProtocolReadListener reuses the same StringBuilder instance across multiple requests. 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.
