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.
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

Compare what a trading-card seller keeps across eBay and Pulltrader selling methods — inside your AI assistant.
A public, read-only Model Context Protocol server that estimates the net amount a trading-card seller keeps when selling the same card through eBay versus Pulltrader's selling methods (marketplace, Fulfilled by Pulltrader, branded storefront, and in-person POS).
Calculations are deterministic and use a dated, versioned fee schedule. The server performs the math itself — it never asks the model to infer fees from prose. eBay figures are clearly labeled estimates.
POST /mcp)https://mcp.pulltrader.app/mcpapp.pulltrader/seller-economicsTrading-card sellers, dealers, and shops deciding where to list a card and how much they'll take home — especially while comparing eBay against alternatives.
| Does | Doesn't |
|---|---|
| Estimate seller fees & net proceeds per method | Look up a card's market value or recent sales |
| Compare eBay (estimated) vs Pulltrader methods | Identify a card from text or image |
| Compute the price needed for a target net (via inputs) | Make any write/account changes |
| State its assumptions and limitations explicitly | Claim one platform is universally cheapest |
Card identification, comparable sales, and "what's it worth" are out of scope for this server (see ROADMAP).
compare_selling_costsCompare estimated fees and seller net proceeds for one trading-card sale across selling methods.

Supported methods: ebay, pulltrader_marketplace, pulltrader_fbp, pulltrader_storefront, pulltrader_pos, and estimated competitor marketplaces tcgplayer, manapool, misprint, fanatics_collect, goldin (off by default — opt in via methods). Competitor figures model fixed-price / Buy Now seller fees only; auction formats (hammer price, buyer's premium, negotiated consignment) are not modeled.
Output (structured): currency, sale_price, methods[] (each with gross_amount, estimated_total_fees, fee_breakdown, estimated_payout, effective_fee_rate, owns_listing, fulfilled_by, where_it_sells, estimated, notes), difference_from_baseline, best_for_seller, assumptions, inputs_used, fee_schedules, fee_schedule_version, warnings, calculated_at, disclaimer, related_url. A concise, neutral human summary is returned as text content.
