MEDIUM
CVSS 3.1
EPSS 0.06%
Description
### Updated 2020-09-16 This entry previously misidentified the problematic behavior. The HTTP request itself is legitimate, but only authorized users should be able to perform it. ### Original Description Blue Ocean Plugin 1.23.2 and earlier does not perform permission checks in several HTTP endpoints implementing connection tests. This allows attackers with Overall/Read permission to connect to an attacker-specified URL. Blue Ocean Plugin 1.23.3 requires Item/Create permission to perform these connection tests.
