DC-80: Improper Authentication
CVE-2026-22099 is a high-severity improper authentication vulnerability in DC-80 from EVbee, with a CVSS 4.0 base score of 8.7 out of 10. It can be exploited from the same local network by an unauthenticated attacker, without any action from a user. The record lists version 1.5.4 as the first without the flaw, so updating DC-80 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.3% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
