Title
MaxKB AWS Bedrock model credential injection leads to remote code execution
Summary
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.
