Jenkins Git client Plugin 3.11.0 and earlier does not perform SSH host key verification when connecting to Git repositories via SSH, enabling man-in-the-middle attacks.

Hammer CLI, a CLI utility for Foreman, before version 0.10.0, did not explicitly set the verify_ssl flag for apipie-bindings that disable it by default. As a result the server certificates are not checked and connections are prone to man-in-the-middle attacks.

The verify_certificate function in lib/vtls/schannel.c in libcurl 7.30.0 through 7.51.0, when built for Windows CE using the schannel TLS backend, makes it easier for remote attackers to conduct man-in-the-middle attacks via a crafted wildcard SAN in a server certificate, as demonstrated by "*.com."

Jenkins View26 Test-Reporting Plugin 1.0.7 and earlier does not perform hostname validation when connecting to the configured View26 server that could be abused using a man-in-the-middle attack to intercept these connections.

FreshService macOS Agent < 4.4.0 and FreshServce Linux Agent < 3.4.0 are vulnerable to TLS Man-in-The-Middle via the FreshAgent client and scheduled update service.
