How should we interpret CVSS severity scores?

CVSS estimates technical severity, but it does not automatically equal business risk. Prioritize using context like internet exposure, asset criticality, known exploitation, and whether compensating controls exist. A Medium CVSS on an exposed production system can be more urgent than a Critical on an isolated non-production host.

Vulnerability Database

Q: What is a Vulnerability (CVE) and why does it matter?

A security vulnerability is a weakness in software, hardware, or configuration that can be exploited to compromise confidentiality, integrity, or availability. Many vulnerabilities are tracked as CVEs (Common Vulnerabilities and Exposures), which provide a standardized identifier so teams can coordinate patching, mitigation, and risk assessment across tools and vendors.

Q: What's the difference between a vulnerability, an exploit, and a zero-day?

A vulnerability is the underlying weakness. An exploit is the method or code used to take advantage of it. A zero-day is a vulnerability that is unknown to the vendor or has no publicly available fix when attackers begin using it. Risk increases sharply when exploitation becomes reliable or widespread.

Q: Why do vulnerabilities keep reappearing in our environment?

Recurring findings usually come from incomplete asset discovery, inconsistent patch management, inherited images, and configuration drift. In modern environments, you also need to watch the software supply chain: dependencies, containers, build pipelines, and third-party services can reintroduce the same weakness even after you patch a single host.

Q: How do we prioritize remediation without burning out the team?

Use a repeatable triage model: focus first on externally exposed assets, high-value systems (identity, VPN, email, production), vulnerabilities with known exploits, and issues that enable remote code execution or privilege escalation. Then enforce patch SLAs and track progress so remediation is steady, not reactive.

Q: How can SynScan help reduce vulnerability risk over time?

SynScan combines attack surface monitoring and continuous security auditing to keep your inventory current, flag high-impact vulnerabilities early, and help you turn raw findings into a practical remediation plan.

Flowise: Remote code execution vulnerability in AirtableAgent.ts caused by lack of input verification when using `Pandas`. — flowise

Improper Control of Generation of Code ('Code Injection')

Description

Summary

“AirtableAgent” is an agent function provided by FlowiseAI that retrieves search results by accessing private datasets from airtable.com. “AirtableAgent” uses Python, along with Pyodide and Pandas, to get and return results.

The user’s input is directly applied to the question parameter within the prompt template and it is reflected to the Python code without any sanitization.

The point is that an attacker can bypass the intended behavior of the LLM and trigger Remote Code Execution through a simple prompt injection.

About Airtable

The airtable.ts function retrieves and processes user datasets stored on Airtable.com through its API.

The usage of Airtable is as shown in the image above. After creating a Chatflow like above, you can ask data-related questions using prompts and receive answers.

Details

// packages/components/nodes/agents/AirtableAgent/AirtableAgent.ts
  let base64String = Buffer.from(JSON.stringify(airtableData)).toString(&#039;base64&#039;)

  const loggerHandler = new ConsoleCallbackHandler(options.logger)
  const callbacks = await additionalCallbacks(nodeData, options)

  const pyodide = await LoadPyodide()

  // First load the csv file and get the dataframe dictionary of column types
  // For example using titanic.csv: {&#039;PassengerId&#039;: &#039;int64&#039;, &#039;Survived&#039;: &#039;int64&#039;, &#039;Pclass&#039;: &#039;int64&#039;, &#039;Name&#039;: &#039;object&#039;, &#039;Sex&#039;: &#039;object&#039;, &#039;Age&#039;: &#039;float64&#039;, &#039;SibSp&#039;: &#039;int64&#039;, &#039;Parch&#039;: &#039;int64&#039;, &#039;Ticket&#039;: &#039;object&#039;, &#039;Fare&#039;: &#039;float64&#039;, &#039;Cabin&#039;: &#039;object&#039;, &#039;Embarked&#039;: &#039;object&#039;}
  let dataframeColDict = &#039;&#039;
  try {
      const code = `import pandas as pd
import base64
import json

base64_string = &quot;${base64String}&quot;

decoded_data = base64.b64decode(base64_string)

json_data = json.loads(decoded_data)

df = pd.DataFrame(json_data)
my_dict = df.dtypes.astype(str).to_dict()
print(my_dict)
json.dumps(my_dict)`
      dataframeColDict = await pyodide.runPythonAsync(code)
  } catch (error) {
      throw new Error(error)
  }

Airtable retrieves results by accessing datasets from airtable.com. When retrieving data, it is fetched as a JSON object encoded in base64. Then, when loading data, it is decoded and converted into an object using Python code.

// packages/components/nodes/agents/AirtableAgent/AirtableAgent.ts
let pythonCode = &#039;&#039;
if (dataframeColDict) {
    const chain = new LLMChain({
        llm: model,
        prompt: PromptTemplate.fromTemplate(systemPrompt),
        verbose: process.env.DEBUG === &#039;true&#039; ? true : false
    })
    const inputs = {
        dict: dataframeColDict,
        question: input
    }
    const res = await chain.call(inputs, [loggerHandler, ...callbacks])
    pythonCode = res?.text
    // Regex to get rid of markdown code blocks syntax
    pythonCode = pythonCode.replace(/^```[a-z]+\n|\n```$/gm, &#039;&#039;)
}

The dataframeColDict and input (user input received via prompt) are passed into the LLMChain function. After that, result of LLMChain is stored in the pythonCode variable.

// packages/components/nodes/agents/AirtableAgent/core.ts
export const systemPrompt = `You are working with a pandas dataframe in Python. The name of the dataframe is df.

The columns and data types of a dataframe are given below as a Python dictionary with keys showing column names and values showing the data types.
{dict}

I will ask question, and you will output the Python code using pandas dataframe to answer my question. Do not provide any explanations. Do not respond with anything except the output of the code.

Question: {question}
Output Code:`

export const finalSystemPrompt = `You are given the question: {question}. You have an answer to the question: {answer}. Rephrase the answer into a standalone answer.
Standalone Answer:`

In prompt template used by the chain call, the dataframeColDict is mapped to the {dict}, and the input is mapped to the {question}.

The purpose of the prompt template (and chain call) is to generate code that extracts data using a Pandas DataFrame and returns only the ‘code’ as a result. However, if a malicious payload containing a prompt injection is provided by an attacker, the value might be returned as-is.

// packages/components/nodes/agents/AirtableAgent/AirtableAgent.ts
let finalResult = &#039;&#039;
if (pythonCode) {
    try {
        const code = `import pandas as pd\n${pythonCode}`
        // TODO: get print console output
        finalResult = await pyodide.runPythonAsync(code)
    } catch (error) {
        throw new Error(`Sorry, I&#039;m unable to find answer for question: &quot;${input}&quot; using follwoing code: &quot;${pythonCode}&quot;`)
    }
}

The returned malicious Python code (pythonCode) will be executed by Pyodide in the next line.

This image shows the result of sending a malicious payload without prompt injection. As you can see, an error is returned, indicating that the Python code did not execute.

However, by adding below payload, the malicious payload executes successfully, resulting in remote code execution (RCE). (Check final payload in PoC Code section)

Frequently Asked Questions

What is a Vulnerability (CVE) and why does it matter?

A security vulnerability is a weakness in software, hardware, or configuration that can be exploited to compromise confidentiality, integrity, or availability. Many vulnerabilities are tracked as CVEs (Common Vulnerabilities and Exposures), which provide a standardized identifier so teams can coordinate patching, mitigation, and risk assessment across tools and vendors.

CVSS (Common Vulnerability Scoring System) estimates technical severity, but it doesn't automatically equal business risk. Prioritize using context like internet exposure, affected asset criticality, known exploitation (proof-of-concept or in-the-wild), and whether compensating controls exist. A "Medium" CVSS on an exposed, production system can be more urgent than a "Critical" on an isolated, non-production host.

A vulnerability is the underlying weakness. An exploit is the method or code used to take advantage of it. A zero-day is a vulnerability that is unknown to the vendor or has no publicly available fix when attackers begin using it. In practice, risk increases sharply when exploitation becomes reliable or widespread.

Recurring findings usually come from incomplete Asset Discovery, inconsistent patch management, inherited images, and configuration drift. In modern environments, you also need to watch the software supply chain: dependencies, containers, build pipelines, and third-party services can reintroduce the same weakness even after you patch a single host. Unknown or unmanaged assets (often called Shadow IT) are a common reason the same issues resurface.

Use a simple, repeatable triage model: focus first on externally exposed assets, high-value systems (identity, VPN, email, production), vulnerabilities with known exploits, and issues that enable remote code execution or privilege escalation. Then enforce patch SLAs and track progress using consistent metrics so remediation is steady, not reactive.

SynScan combines attack surface monitoring and continuous security auditing to keep your inventory current, flag high-impact vulnerabilities early, and help you turn raw findings into a practical remediation plan.
