Executive Summary

This vulnerability exists in Warp, an agentic development environment, specifically in versions from 0.2025.04.09.08.11.stable_00 up to but not including 0.2026.05.06.15.42.stable_01. It involves a command execution policy bypass in the Agent code search tools. The affected Grep and FileGlob actions are intended to be read or search operations, but their implementations construct shell command strings using inputs controlled by the Agent, such as search text, paths, and glob patterns. These constructed commands are then executed in the active terminal session, which can lead to unintended command execution.

Impact Analysis

This vulnerability can have serious impacts because it allows an attacker to execute arbitrary commands in the active terminal session. According to the CVSS score of 7.8, it requires local access with low privileges and user interaction, but it can lead to high confidentiality, integrity, and availability impacts. This means sensitive data could be exposed or altered, and system availability could be compromised.

Mitigation Strategies

The vulnerability is fixed in Warp version 0.2026.05.06.15.42.stable_01. Immediate mitigation involves upgrading Warp to this fixed version or later.

Compliance Impact

CVE-2026-48703 is a command injection vulnerability that allows attackers to execute arbitrary commands in the Warp terminal session by bypassing command execution policies. This can lead to unauthorized access and potential compromise of confidentiality, integrity, and availability of data handled by the affected system.

Such a vulnerability could impact compliance with common standards and regulations like GDPR and HIPAA, which require protection of sensitive data and prevention of unauthorized access. The high severity and potential for data compromise mean that organizations using affected Warp versions might face increased risk of non-compliance if the vulnerability is exploited.

Mitigation by updating to the patched version is essential to maintain compliance and reduce the risk of data breaches or unauthorized command execution that could violate regulatory requirements.

Detection Guidance

This vulnerability involves command execution policy bypass in Warp's Agent code search tools, specifically in the Grep and FileGlob actions that improperly build shell command strings from user-controlled inputs.

Detection on your system would involve monitoring or inspecting the use of Warp versions from 0.2025.04.09.08.11.stable_00 up to but not including 0.2026.05.06.15.42.stable_01, especially focusing on the execution of Grep and FileGlob actions within Warp's Agent.

Since the vulnerability requires user interaction and involves execution of shell commands constructed from search text, paths, or glob patterns, you can look for suspicious or unexpected command executions originating from Warp sessions.

Suggested commands to detect potential exploitation attempts or presence of vulnerable Warp versions include:

• Check the installed Warp version: `warp --version` or check the Warp application metadata to confirm if it is within the vulnerable range.
• Monitor running processes for Warp Agent activity and inspect command lines for suspicious patterns, e.g., using `ps aux | grep warp` or equivalent.
• Audit shell command history for unusual commands that may have been injected via Warp's code search tools.
• Use system auditing tools (like auditd on Linux) to log executions of shell commands initiated by Warp processes.

Ultimately, the recommended mitigation is to update Warp to version v0.2026.05.06.15.42.stable_01 or later, which contains the fix for this vulnerability.
