GHSA-46r8-9cj7-pw6g · Severity: medium · Ecosystem: pip — OpenStack Compute (Nova) Improper Input Validation
The (1) EC2 and (2) OS APIs in OpenStack Compute (Nova) Folsom (2012.2), Essex (2012.1), and Diablo (2011.3) do not properly check the protocol when security groups are created and the network protocol is not specified entirely in lowercase, which allows remote attackers to bypass intended access restrictions.

Core evidence: 2 public exploit reference(s) are indexed (Exploit-DB). EPSS rose +1.45% over the last day, indicating growing attacker interest. Mandatory action: Public exploits are available—assess exposure, apply mitigations, and prioritize patching.
Risk is dynamic; we continuously reassess and refresh what is shown on this page as upstream context changes.
