Nomad Vulnerable To Incorrect ACL Policy Lookup Attached To A Job
Noroxi assessment
Priority: Monitor (action score 32/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.51% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: HashiCorp Nomad 1.10.2; HashiCorp Nomad Enterprise 1.10.2, 1.8.14, 1.9.10.
Low priority for now. Upgrade to HashiCorp Nomad 1.10.2; HashiCorp Nomad Enterprise 1.10.2, 1.8.14, 1.9.10 or later.
