CVE-2026-34430 is a critical sandbox escape vulnerability (CVSS 9.6) affecting ByteDance Deer-Flow versions prior to commit 92c7a20. This flaw allows attackers to execute arbitrary commands on the host system by bypassing regex validation in bash tool handling, enabling them to read and modify files outside the sandbox. The attack vector is network-based with low complexity, but requires user interaction, leading to high impact on confidentiality, integrity, and availability. There are no known public exploits or active exploitation listed on the KEV catalog. However, the vulnerability has garnered some community discussion.
