Description
CVE-2026-44097 is a vulnerability in Phoenix Contact CHARX SEC-3150 that allows a low-privileged remote attacker with operator access to upload arbitrary files via the REST endpoint used for firmware updates. This can lead to persistent storage of attacker-controlled files and may exhaust device resources, potentially causing a denial-of-service condition.
