Executive Summary

This vulnerability exists in Warp, an agentic development environment, in versions from 0.2023.10.24.08.03.stable_00 up to but not including 0.2026.05.06.15.42.stable_01. Warp may open executable local files through the operating system's default file handler when a user clicks on a local-file link embedded in a malicious Markdown document or project. Such links appear as normal rendered content, but clicking them causes Warp to route the resolved local file to a platform file opener instead of restricting the action to safe viewer or editor targets.

Impact Analysis

The impact of this vulnerability is significant because it allows remote attackers to execute local files on the user's system without proper restrictions. If a user opens a malicious Markdown document in Warp and clicks on a crafted local-file link, it may lead to the execution of potentially harmful executable files. This can result in complete compromise of confidentiality, integrity, and availability of the affected system.

Mitigation Strategies

To mitigate this vulnerability, update Warp to version 0.2026.05.06.15.42.stable_01 or later, where the issue is fixed.

Avoid opening Markdown documents or projects from untrusted sources that may contain malicious local-file links.

Compliance Impact

This vulnerability allows a malicious Markdown document to open executable local files through the operating system's default file handler when clicked by a user, potentially leading to arbitrary code execution with the privileges of the Warp user.

Such unauthorized code execution risks compromising the confidentiality, integrity, and availability of data handled within the Warp environment.

In contexts where Warp is used to process or access sensitive personal data protected under regulations like GDPR or HIPAA, exploitation of this vulnerability could lead to data breaches or unauthorized access, thereby impacting compliance with these standards.

Organizations relying on Warp should consider this risk in their security assessments and apply the provided patch or mitigation to maintain compliance.

Detection Guidance

This vulnerability involves Warp opening executable local files through Markdown links when clicked by a user. Detection involves identifying if vulnerable versions of Warp are in use and monitoring user interactions with Markdown files containing local-file links.

To detect the vulnerability on your system, first check the Warp version installed. Versions from v0.2023.10.24.08.03.stable_00 up to but not including v0.2026.05.06.15.42.stable_01 are affected.

• On macOS or Linux, run: warp --version
• On Windows, check Warp version via the application About menu or command line if supported.

To detect exploitation attempts, monitor for user clicks on Markdown files containing local-file links that could open executables. Since exploitation requires user interaction, network detection is limited, but you can audit file access logs or monitor process launches triggered by Warp.

No specific commands are provided in the resources for direct detection of exploitation, but general steps include:

• Search for Markdown files with local-file links in projects or directories used with Warp.
• Audit Warp logs or system logs for unexpected file openings or process executions initiated by Warp.
• Update Warp to version v0.2026.05.06.15.42.stable_01 or later to mitigate the vulnerability.
