Synopsis

A source control application running on the remote web server is affected by an improper access control vulnerability.

Description

According to its self-reported version, the instance of GitLab running on the remote web server is 12.10.0 prior to 14.2.6, 13.0.0 prior to 14.3.4, or 13.1.0 prior to 14.4.1. It is, therefore, affected by an improper access control vulnerability due to pipelines activated by default on imported projects. An unauthenticated, remote attacker could exploit this vulnerability to lead to information disclosure.
