An issue was discovered in Mattermost Server before 5.12.0.

MEDIUM 5.3EPSS 0.92%

Does this matter?

Lower severity and a low EPSS score (0.92%). Track it; it rarely justifies an emergency change on its own.

Description

An issue was discovered in Mattermost Server before 5.12.0. Use of a Proxy HTTP header, rather than the source address in an IP packet header, for obtaining IP address information was mishandled.
