Description
From CVE.org
HTTP request/response smuggling vulnerability in HAProxy version 2.7.0, and 2.6.1 to 2.6.7 allows a remote attacker to alter a legitimate user's request. As a result, the attacker may obtain sensitive information or cause a denial-of-service (DoS) condition.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Red Hat CVSS v3 Score Explanation
Confidentiality, Integrity, and Availability metrics are Low, because:
- Successful exploitation may lead to some loss of confidentiality, but it's not under the attacker's control what information will be obtained.
- Theoretically, an attacker may be able to modify some data but does not have control over the consequences of that modification.
- An attacker is not able to determine if successful exploitation will affect the availability of the target environment.
