Cisco disclosed six new vulnerabilities in its SD-WAN Manager on February 25, with three already exploited in the wild. While CVE-2026-20127 grabbed headlines with its perfect 10 CVSS score and three years of zero-day exploitation, researchers at VulnCheck warn that fake proof-of-concept exploits are muddying the waters.

Meanwhile, CVE-2026-20133 is flying under the radar despite allowing attackers to steal private keys and escalate to root access. VulnCheck found most public PoCs for the high-profile bug were either fake or misleading, with one actually exploiting three different vulnerabilities instead.

The chaos highlights how organizations struggle to prioritize patches amid overwhelming vulnerability noise and unreliable exploit code.
