CVE-2026-26068 is a critical command injection vulnerability affecting emp3r0r, a C2 framework designed for Linux environments, prior to version 3.21.1. The flaw allows untrusted agent metadata, specifically Transport and Hostname, to be interpolated into tmux shell command strings executed on the operator host, leading to remote code execution. With a CVSS score of 9.9 (CRITICAL), this vulnerability is easily exploitable over the network with low privileges and no user interaction, enabling complete compromise of confidentiality, integrity, and availability. While no public exploit intelligence, active exploitation, or significant community discussion has been observed, the high severity warrants immediate patching to version 3.21.1.
