prior to 7.21.4, 8.0 prior to 8.0.3, 8.1 prior to 8.1.3, 8.2 prior to 8.2.2 or 8.3 prior to 8.3.1. It is, therefore,
affected by a remote code execution vulnerability. A remote attacker with read permissions to a public or private
Bitbucket repository can send a malicious HTTP request leading to arbitrary code execution.

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