OpenStack Nova-LXD before 13.1.1 uses the wrong name for the veth pairs when applying Neutron security group rules for instances, which allows remote attackers to bypass intended security restrictions.
CVE-2017-5936
This high-severity CVE scores 7.5 under NVD CVSS v3. EPSS exploit probability: 2.5%, top 15% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
