GoCD is an open source a continuous delivery server. The bundled gocd-ldap-authentication-plugin included with the GoCD Server fails to correctly escape special characters when using the username to construct LDAP queries. While this does not directly allow arbitrary LDAP data exfiltration, it can allow an existing LDAP-authenticated GoCD user with malicious intent to construct and execute malicious queries, allowing them to deduce facts about other users or entries within the LDAP database (e.g alternate fields, usernames, hashed passwords etc) through brute force mechanisms. This only affects users who have a working LDAP authorization configuration enabled on their GoCD server, and only is exploitable by users authenticating using such an LDAP configuration. This issue has been fixed in GoCD 22.1.0, which is bundled with gocd-ldap-authentication-plugin v2.2.0-144.

Adding a new pipeline in GoCD server version 21.3.0 has a functionality that could be abused to do an un-intended action in order to achieve a Server Side Request Forgery (SSRF). NOTE: the vendor's position is that the observed behavior is not a vulnerability, because the product's design allows an admin to configure outbound requests

In GoCD, versions 19.6.0 to 21.1.0 are vulnerable to Cross-Site Request Forgery due to missing CSRF protection at the `/go/api/config/backup` endpoint. An attacker can trick a victim to click on a malicious link which could change backup configurations or execute system commands in the post_backup_script field.
