CVE-2026-48721
Warp: Env-var prefixes can lead to denylisted command autoexecution
Warp is an agentic development environment. From 0.2025.10.08.08.12.stable_00 until 0.2026.05.06.15.42.stable_01, Warp contains a command execution permission-check bypass in the default unsandboxed CLI agent profile. The CLI profile is non-interactive and relies on a command denylist as a safety boundary for commands that should require confirmation. Because command strings were checked before canonicalizing leading environment-variable assignments, an attacker who can influence the agent's command output may cause denylisted commands to be treated as non-denylisted. This vulnerability is fixed in 0.2026.05.06.15.42.stable_01.
