Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Cursor is a code editor built for programming with AI. In versions 1.7 and below, a vulnerability in the way Cursor CLI Agent protects its sensitive files (i.e. */.cursor/cli.json) allows attackers to modify the content of the files through prompt injection, thus achieving remote code execution. A prompt injection can lead to full RCE through modifying sensitive files on case-insensitive filesystems. This issue is fixed in a commit, 25b418f, but has yet to be released as of October 3, 2025.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Cursor CLI Agent fails to properly protect sensitive configuration files (*/.cursor/cli.json) from modification through prompt injection. Attackers can inject malicious prompts to modify these sensitive files, which on case-insensitive filesystems can lead to arbitrary code execution with the privileges of the Cursor process.

MitigationSince the patch is not yet released, users should avoid running the Cursor CLI Agent with untrusted/provided prompts and monitor .cursor/cli.json for unauthorized modifications until version 1.8 or later is available.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check installed Cursor version
    Locate the Cursor application and query its version number (typically via About menu or application metadata)
    Affected if version is 1.7 or lower (the vulnerable versions)
  2. Verify CLI Agent feature usage
    Determine whether the Cursor CLI Agent has been invoked or configured - check for any CLI agent processes, logs, or configuration indicating recent agent usage
    Affected if CLI Agent feature has been used with external or untrusted prompts
  3. Inspect .cursor/cli.json for unauthorized changes
    Locate the .cursor/cli.json file in the user's home directory or project directory and examine its contents for any unexpected modifications or suspicious entries
    Affected if the file contains unexpected configurations or modifications you did not make
  4. Check filesystem type for case-insensitivity
    Identify if the filesystem is case-insensitive (default on Windows and macOS) - this is relevant because the vulnerability leverages case-insensitive file handling
    Affected if running on a case-insensitive filesystem (Windows APFS, macOS default)

You are affected if running Cursor version 1.7 or lower, have used the CLI Agent feature, and notice unexpected modifications to .cursor/cli.json especially on case-insensitive filesystems.

Upgrade available Upgrade to a release after 1.7
Interim mitigation

Since the patch is not yet released, users should avoid running the Cursor CLI Agent with untrusted/provided prompts and monitor .cursor/cli.json for unauthorized modifications until version 1.8 or later is available.

Recommended fix High confidence
  1. Monitor Cursor's official release channels for version 1.8 or later which should contain the security fix
  2. Do not use the Cursor CLI Agent with untrusted input until the patched version is available
  3. If using Cursor CLI Agent, avoid processing prompts from untrusted sources that could inject malicious instructions
  4. Review any automated pipelines using Cursor for potential prompt injection vectors
