Published by the GitHub Advisory Database at 3 Mar 2021, 23:01 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `com.datadoghq:datadog-api-client` (Maven): affected `>=1.0.0-beta.6, <1.0.0-beta.9`; fixed in `1.0.0-beta.9`

## Machine-written summary

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

> The Maven package com.datadoghq:datadog-api-client, versions from 1.0.0-beta.6 before 1.0.0-beta.9, can leave files downloaded through the API readable by other local users on unix-like systems, because a temporary file is created with world-readable permissions in a shared temporary directory. An attacker needs a local account on the same system. Upgrade to version 1.0.0-beta.9, which removes the affected unused code. The source's suggested workaround is to set java.io.tmpdir to a private directory.

## 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-2cxf-6567-7pp6>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
