Published by the GitHub Advisory Database at 20 May 2024, 20:15 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `requests` (PyPI): affected `<2.32.0`; fixed in `2.32.0`

## Machine-written summary

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

> The requests package, versions before 2.32.0, can keep TLS certificate verification disabled for later requests in a Session. If the first request to an origin uses verify=False, pooled connections may skip verification even when verify=True is set later. An attacker positioned on the network path could then intercept or alter traffic. Upgrade requests to 2.32.0 or later.

## 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-9wx4-h78v-vm56>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
