Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

In LemonLDAP::NG (aka lemonldap-ng) before 2.0.7, the default Apache HTTP Server configuration does not properly restrict access to SOAP/REST endpoints (when some LemonLDAP::NG setup options are used). For example, an attacker can insert index.fcgi/index.fcgi into a URL to bypass a Require directive.
