## Affected packages

- `github.com/quic-go/quic-go` (Go): affected `<0.48.2`; fixed in `0.48.2`

## Machine-written summary

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

> The quic-go package for Go, versions before 0.48.2, is affected. An off-path attacker who knows the client's IP address and port can inject an ICMP Packet Too Large message, causing the kernel to report "message too large" errors when quic-go sends packets. This can disrupt an established QUIC connection, even after the handshake. Upgrade to version 0.48.2 or later. Dropping ICMP Unreachable packets with iptables is a possible workaround.

## 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-px8v-pp82-rcvr>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
