Today we released GitLab Community Edition 7.2.1 and GitLab Enterprise Edition 7.2.1. This is a security release which remedies an XSS vulnerability in GitLab. In addition to this 7.2.1 makes the tag-to-label migration for users upgrading from GitLab 7.1 and earlier more robust.
This XSS vulnerability affects GitLab 7.2.0 and earlier.
The vulnerability patched by this release allows an attacker to carry out a cross-site scripting (XSS) attack against users with a session on an affected GitLab server. In order to exploit this vulnerability, the attacker needs to have commit access to a repository on the affected GitLab server.
We would like to thank Jakub Zoczek for his responsible disclosure of this issue to us.
