About this tag
CVE-2026-67277 is a MikroTik RouterOS vulnerability that CISA added to its Known Exploited Vulnerabilities catalog after evidence of exploitation in the wild.

Coverage here focuses on the CISA KEV alert and remediation guidance for WindowsForum readers managing network edge equipment.
