# amazon-redshift-python-driver vulnerable to Remote Code Execution via eval() Injection

Advisory record · `GHSA-29h4-r29x-hchv`

- **Identifiers:** `GHSA-29h4-r29x-hchv` · `CVE-2026-8838` · `PYSEC-2026-521`
- **State:** Confirmed
- **Severity:** CVSS 9.3 Critical
- **Critical:** Yes: CVSS 9+
- **Weakness (CWE):** [CWE-94](https://cwe.mitre.org/data/definitions/94.html)
- **Tags:** [Code injection](https://agentprime.io/advisories/tag/code-injection.md)
- **Published:** 29 May 2026

Published by the GitHub Advisory Database at 29 May 2026, 19:32 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Critical

Critical, because:

- CVSS score 9.3: 9.0 or more.

How we decide what’s critical: <https://agentprime.io/advisories/critical.md>

## Affected packages

- `redshift-connector` (PyPI): affected `<2.1.14`; fixed in `2.1.14`

## Machine-written summary

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

> The redshift-connector package (the official Python driver for Amazon Redshift) is vulnerable in versions before 2.1.14. A rogue database server or a man-in-the-middle attacker can send crafted query responses that the driver processes without adequate validation, which could lead to arbitrary code execution in the client process. Upgrade to redshift-connector 2.1.14 or later.

Written 5 Nov 2026.

## 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-29h4-r29x-hchv>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
