    CVE-2026-26201 (GCVE-0-2026-26201)

    Vulnerability from cvelistv5 – Published: 2026-02-19 19:21 – Updated: 2026-02-19 21:22

    Title
    emp3r0r Affected by Concurrent Map Access DoS (panic/crash)
    Summary
    emp3r0r is a C2 designed by Linux users for Linux environments. Prior to version 3.21.2, multiple shared maps are accessed without consistent synchronization across goroutines. Under concurrent activity, Go runtime can trigger `fatal error: concurrent map read and map write`, causing C2 process crash (availability loss). Version 3.21.2 fixes this issue.

    CVE-2026-26068 (GCVE-0-2026-26068)

    Vulnerability from cvelistv5 – Published: 2026-02-12 22:01 – Updated: 2026-02-13 17:17
    VLAI
    Title
    emp3r0r Agent-Controlled Metadata to Operator RCE (tmux Command Injection)
    Summary
    emp3r0r is a stealth-focused C2 designed by Linux users for Linux environments. Prior to 3.21.1, untrusted agent metadata (Transport, Hostname) is accepted during check-in and later interpolated into tmux shell command strings executed via /bin/sh -c. This enables command injection and remote code execution on the operator host. This vulnerability is fixed in 3.21.1.
    Severity
    9.3 (Critical)
