Attack profile from CVSS 4.0 · CNA. Fix status from CNA. Impact type from CWE-863.
Summary
Froxlor from 0.10.0 before 2.3.15 contains an authorization bypass in the Admins.get API command (CWE-863). A reseller can pair their own loginname with another admin's numeric id, so the API returns that admin's record, including contact email, IP allow-lists, resource limits, notes and login history. The CVSS 4.0 vector requires a low-privileged authenticated attacker over the network.
