## Affected packages

- `node-forge` (npm): affected `<1.4.1`; fixed in `1.4.1`

## Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

> Affected: the node-forge npm package, versions below 1.4.1. In TLS record processing, connections from forge.tls.createConnection() handle received records recursively, so one chunk containing thousands of small records (such as heartbeat records, which are accepted before the handshake) can exhaust the call stack. An unauthenticated peer that can connect to a forge TLS endpoint can send such a chunk, causing a RangeError that crashes Node.js processes using the documented socket wiring. Upgrade to node-forge 1.4.1, which processes records in a loop.

## Check whether this affects you

A Match means an installed version is in the affected range above. Most don’t affect the app; agentprime hasn’t analysed this one yet.

- With the agentprime MCP server (<https://api.agentprime.io/mcp>), ask your agent to check the project: `check_lockfile` sends a lockfile, `check_packages` a list of installed packages, and both return the Matches and the upgrades that clear them. `get_advisory` returns this record. Setup: <https://agentprime.io/mcp.md>
- In a browser: <https://agentprime.io/check/> reads your lockfile in the browser, never uploading it.
- Whether it touches your code, with file and line: the Claude Code plugin, <https://agentprime.io/plugin.md>
- As JSON: <https://api.agentprime.io/v1/advisories/GHSA-hqq3-7jhf-c5jx>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
