A source control application running on the remote web server is affected by hash overwrite vulnerability.


In GitLab EE/CE before 15.6.1, 15.5.5, and 15.4.6 using a branch with a hexadecimal name could override an existing hash.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
