What is CVE-2026-32720?
CVE-2026-32720 is a high-severity missing authorization vulnerability in ctfer-io monitoring, published on 13 Mar 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The CTFer.io Monitoring component is in charge of the collection, process and storage of various signals (i.e. logs, metrics and distributed traces). Prior to 0.2.1, due to a mis-written NetworkPolicy, a malicious actor can pivot from a component to any other namespace. This breaks the security-by-default property expected as part of the deployment program, leading to a potential lateral movement. This vulnerability is fixed in 0.2.1.
