CVE-2026-20062 is an improper access control vulnerability in the CLI of Cisco Secure Firewall Adaptive Security Appliance (ASA) Software when running in multiple context mode. The issue affects Secure Copy Protocol (SCP) operations when the CiscoSSH stack is enabled. An authenticated local attacker with administrative privileges in one non-admin context can issue crafted SCP copy commands that bypass intended context isolation and access files belonging to other contexts. This can include sensitive configuration data associated with admin and system contexts. The vulnerability stems from insufficient authorization checks on cross-context SCP file operations. The attacker cannot enumerate files in other contexts and must know the exact target path, which increases exploitation complexity.
