CVE-2026-48721: CWE-180: Incorrect Behavior Order: Validate Before Canonicalize in warpdotdev warp
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.
AI Analysis
Technical Summary
CVE-2026-48721 is a vulnerability in the Warp development environment affecting the default unsandboxed CLI agent profile. The CLI profile uses a denylist to restrict certain commands requiring confirmation. However, the validation of commands occurs before canonicalization of leading environment-variable assignments, which can be manipulated by an attacker controlling the agent's command output. This results in denylisted commands being incorrectly treated as allowed, effectively bypassing permission checks. The vulnerability is resolved in Warp version 0.2026.05.06.15.42.stable_01.
Potential Impact
An attacker able to influence the agent's command output can bypass the command denylist safety mechanism in the unsandboxed CLI profile, potentially leading to unauthorized command execution with high confidentiality, integrity, and availability impact as indicated by the CVSS score of 8.6.
Mitigation Recommendations
A fix is available in Warp version 0.2026.05.06.15.42.stable_01. Users should upgrade to this version to remediate the vulnerability. Patch status is not explicitly confirmed beyond this version information; therefore, verify with the vendor advisory for the latest remediation guidance.
