Summary
A binary planting vulnerability in Cursor for Windows version 3.2.16 allows remote attackers to achieve arbitrary code execution by placing a malicious git.exe in the repository root. When a developer clones and opens a crafted repository, Cursor automatically executes the malicious binary without user interaction.
Risk Assessment
An attacker can take over the developer's workstation, gaining access to sensitive data, source code, and credentials, potentially compromising the entire organization.
Recommendation
Update Cursor for Windows to the latest version that fixes this vulnerability. Until updated, avoid cloning and opening repositories from untrusted sources.
Other vulnerabilities in Cursor
See all- CVE-2026-73218High
Cursor IDE for macOS before version 3.0.0 allows an agent running in Auto-Run Sandbox mode, when Docker Desktop and Dev Containers CLI are installed, to launch a privileged container and mount Docker's virtiofs0, granting read/write access to the user's home directory and enabling host command execution with the user's privileges without an additional permission prompt.
- CVE-2026-73217High
Cursor IDE for macOS before version 3.1.2 allows an agent running in Auto-Run Sandbox mode to replace a virtual environment's Python executable with a malicious wrapper that the Microsoft Python extension invokes outside the sandbox, allowing arbitrary host commands with the user's privileges, including modifying files outside the workspace and launching applications.
- CVE-2026-61613High
A vulnerability in Cursor editor before 03/31/2026 allowed attacker-controlled web content to connect to an unauthenticated local agent endpoint, enabling code execution in the cloud agent sandbox and access to files, repositories, environment variables, credentials, and GitHub App tokens. The issue was fixed on 03/31/2026 by requiring authentication for the relevant endpoint.
Original NVD description (English source)
Cursor for Windows version 3.2.16 contains a binary planting vulnerability that allows remote attackers to achieve arbitrary code execution by placing a malicious git.exe file in the repository root directory. When a developer clones and opens a crafted repository, Cursor automatically resolves and executes the workspace-resident git.exe during IDE startup and on a recurring timed cadence without any user interaction, running the malicious binary under the privileges of the current user.
