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

CVE-2018-7408high · fixedCVSS 7.8

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.

Affected: >= 0Fixed in 5.7.1source →

CVE-2013-4116info · 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.

CVE-2019-16777high · fixedCVSS 7.7

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

README

knowledge-base-server

Make every AI agent you use smarter.

This is not just a search engine. It is an intelligence pipeline that turns raw information into refined, retrievable knowledge -- and gets smarter every session.

The Problem

AI agents are stateless. Every session starts from zero. You end up:

Copy-pasting context between sessions
Re-explaining your codebase, architecture, and preferences
Watching agents hallucinate because they lack YOUR information
Losing debugging insights that took hours to discover
Running multiple agents that can't share what they know

The smarter the model, the more painful the amnesia. Context is the bottleneck, not intelligence.

The Solution

knowledge-base-server sits between your knowledge and your AI agents. It ingests everything -- your Obsidian vault, code, documents, YouTube transcripts, X bookmarks, terminal sessions -- and serves it through MCP and REST APIs. Every agent you use reads from and writes to the same brain.

Your AI gets smarter every day. Every session builds on the last.

Code Repos ----------+
YouTube Transcripts --+---> [ KB Server ] ---> SQLite + FTS5 ---> [ MCP ] ---> Claude Code
X/Twitter Bookmarks -+         |                   |                          Codex CLI

Obsidian is the source of truth -- the human layer where you organize, link, and curate knowledge. The KB server is the optimized retrieval layer that makes it AI-ready with minimal token usage.

How It Works: The Intelligence Pipeline

This is the core differentiator. Raw information flows through seven layers to become actionable intelligence:

1. Capture Layer

Ingest from everywhere:

Obsidian vault -- bidirectional sync, auto-indexes on changes
YouTube transcripts -- via yt-dlp or kb_capture_youtube
X/Twitter bookmarks -- browser export to markdown, auto-ingest
Web articles -- Obsidian Web Clipper or kb_capture_web
Terminal sessions -- kb_capture_session records what worked, failed, and why
Bug fixes -- kb_capture_fix records symptom, cause, and resolution
Code, PDFs, text -- 20+ file types with automatic type detection

Every source enters the system as a raw capture, ready for processing.

2. Classification Layer

The kb_classify tool runs AI classification on unprocessed content:

Assigns document type (research, idea, workflow, lesson, fix, decision, session)
Auto-generates tags and project routing
Writes structured summaries and key topics
Adds confidence scoring
Enforces frontmatter discipline on every note

Raw clippings become structured, searchable knowledge automatically.

3. Promotion Pipeline

Raw captures get refined into higher-value knowledge artifacts:

Captures in inbox get normalized into sources
Sources get promoted to insights, lessons, decisions, runbooks
The kb_promote tool extracts structured knowledge from raw material
Higher-value knowledge ranks higher in retrieval
The system distinguishes signal from noise automatically

4. Synthesis Layer

The kb_synthesize tool connects dots across sources:

Reads recent notes across all types and projects
Identifies recurring themes, patterns, and bottlenecks
Surfaces opportunities and workflow improvements
Generates cross-cutting insights that no single source contains
This is where raw information becomes actionable int
