CVE-2022-29244high · fixedCVSS 7.5

Packing does not respect root-level ignore files in workspaces

### Impact `npm pack` ignores root-level `.gitignore` & `.npmignore` file exclusion directives when run in a workspace or with a workspace flag (ie. `--workspaces`, `--workspace=<name>`). Anyone who has run `npm pack` or `npm publish` with workspaces, as of [v7.9.0](https://github.com/npm/cli/releases/tag/v7.9.0) & [v7.13.0](https://github.com/npm/cli/releases/tag/v7.13.0) respectively, may be affected and have published files into the npm registry they did not intend to include. ### Patch - Up

Incorrect Permission Assignment for Critical Resource in NPM

An issue was discovered in an npm 5.7.0 2018-02-21 pre-release (marked as "next: 5.7.0" and therefore automatically installed by an "npm upgrade -g npm" command, and also announced in the vendor's blog without mention of pre-release status). It might allow local users to bypass intended filesystem access restrictions because ownerships of /etc and /usr directories are being changed unexpectedly, related to a "correctMkdir" issue.

CVE-2013-4116low · fixed

Local Privilege Escalation in npm

Affected versions of `npm` use predictable temporary file names during archive unpacking. If an attacker can create a symbolic link at the location of one of these temporary file names, the attacker can arbitrarily write to any file that the user which owns the `npm` process has permission to write to, potentially resulting in local privilege escalation. ## Recommendation Update to version 1.3.3 or later.

npm CLI exposing sensitive information through logs

Versions of the npm CLI prior to 6.14.6 are vulnerable to an information exposure vulnerability through log files. The CLI supports URLs like `<protocol>://[<user>[:<password>]@]<hostname>[:<port>][:][/]<path>`. The password value is not redacted and is printed to stdout and also to any generated log files.

npm Vulnerable to Global node_modules Binary Overwrite

Versions of the npm CLI prior to 6.13.4 are vulnerable to a Global node_modules Binary Overwrite. It fails to prevent existing globally-installed binaries to be overwritten by other package installations. For example, if a package was installed globally and created a `serve` binary, any subsequent installs of packages that also create a `serve` binary would overwrite the first binary. This will not overwrite system binaries but only binaries put into the global node_modules directory. This b

Search all 3 million of your files. In milliseconds.

Windows, MacOS and Linux already know where every last file is.

Now your agents do too.

Real life examples

November 2026 - I was about to wipe my C: drive for a Windows 11 + Linux dual boot and needed to know what on it was irreplaceable: notes, game saves, lab-instrument software, obscure driver installers. An agent audited ~900 GB of user data and produced a 33 GB backup list, separating what had to be kept from what was already on another drive or trivially re-downloadable. One * is:folder call returned all 178,556 folders with aggregate sizes, replacing a dozen recursive walks. The indexer also read C:\Windows\System32\config and Program Files\WindowsApps - both refused to a normal account - which corrected a 7.4 GB undercount in the agent's own PowerShell numbers, and a content:chemstation search surfaced two projects on a second drive that directory listing had never found.

The agent then got the query syntax wrong in five different ways, and every wrong query came back as a confident answer rather than an error: aggregate_files(query="*") inflated totals 4x, a missing include_all silently dropped 24 GB, OR instead of the pipe returned zero. That session is why the server now ships its rules in the initialize handshake and returns a parsed block plus warnings with a concrete fix on every response. It also turned up two real bugs: regex: returned nothing for every MCP query, and a file carrying a 166-byte Zone.Identifier alternate data stream was indexed as 166 bytes instead of its actual 4.4 GB.

October 2026 - A serious security bug was published in PHP on 21 October 2026. It lets an attacker run their own code on a web server that runs PHP. instant-file-search-MCP-server tools were used to assess in a fraction-of-a-second whether any of my dozens of codebases were affected; one indexed count across the entire projects folder using count_files, with dependency and git folders excluded. That single call collapsed the question to machine-wide scope. Zero PHP files across all of B:\Projects, with the noise folders excluded. It converted a repo-local negative into a whole-machine negative

September 2026 - I screwed up and moved all my LM Studio models to the wrong folder, stopped copying halfway through, and messed up the entire directory structure. I didn't know which files to save or where to move them. Using Instant File Search tools, the agent quickly found all the files and determined how to fix the mess. (removed the thinking parts)

How to Install (Recommended)

Have your AI agent do it:

Install Instant File Search MCP from https://github.com/clayleopardlabs/instant-file-search-MCP-server for this computer and this AI app. Use the repository's recommended automatic installer for this operating system, configure this AI app, and complete the native indexer installation with any required OS permissions. Do not treat a fallback-only setup as complete. Verify the installation with the repository's documented diagnostic, restart this AI app if needed, then tell me which client was configured and whether verification passed.

Then the AI uses the following auto installers which pull from the releases. Which you can use manually yourself if you want. They detect if you have Hermes, opencode, DeepSeek Harness, and ohmyopencode. If you have OMO, normally subagents don't have access to top-level MCP servers so this adds a plugin to allow them to use the tools too. The goal is that the tools from instant-file-search become the new go-to tools instead of the much slower an inefficient defaults.
