CVE-2026-20262 Is Rated 6.5. It Can Get You Root. Here Is Why That Gap Matters.
Cisco Catalyst SD-WAN Manager's actively exploited file write flaw is a case study in how CVSS scores can dramatically understate real attack chains.
- A CVSS score of 6.5 does not capture chaining potential: CVE-2026-20262 escalates to root in three steps once an attacker has valid credentials.
- Cisco PSIRT confirmed active exploitation in the wild before patches were broadly applied; upgrade Catalyst SD-WAN Manager to a fixed release now.
- Management-plane compromise is categorically more dangerous than an endpoint compromise; treat any flaw in SD-WAN Manager as higher priority than its base score implies.
