k8sGPT Operator Vulnerable to Prompt Injection

hello@craftedsignal.io — Fri, 24 Apr 2026 16:41:39 +0000

k8sGPT is an open-source project that leverages AI to analyze and remediate Kubernetes cluster issues. A critical vulnerability exists in k8sGPT versions prior to 0.4.32, specifically within the k8sGPT-Operator component. The vulnerability stems from the auto-remediation pipeline in object_to_execution.go, which deserializes AI-generated YAML directly into a Kubernetes Deployment object without adequate validation. This lack of validation allows for prompt injection, where malicious YAML payloads generated by the AI can overwrite or modify existing deployments in unexpected ways. This can be exploited by attackers to gain control over resources within the Kubernetes cluster by crafting malicious AI prompts to inject malicious code into deployment configurations.

Attack Chain

An attacker crafts a malicious prompt designed to generate YAML code that includes malicious configurations (e.g., mounting host volumes, privileged containers).
The k8sGPT-Operator receives the prompt and uses its AI engine to generate a YAML manifest for a Kubernetes Deployment object.
The object_to_execution.go component deserializes the AI-generated YAML manifest directly into a Kubernetes Deployment object.
Due to the lack of validation, the malicious configurations within the YAML manifest are not detected.
The k8sGPT-Operator applies the modified Deployment object to the Kubernetes cluster via the Kubernetes API.
The Kubernetes scheduler creates pods based on the compromised Deployment object, potentially executing malicious code within the cluster.
The attacker gains control over the deployed pod, potentially escalating privileges to other resources within the cluster.

Impact

Successful exploitation of this vulnerability allows an attacker to inject arbitrary code into Kubernetes deployments, potentially leading to full cluster compromise. While the precise number of affected installations is unknown, any k8sGPT deployment prior to version 0.4.32 is susceptible. This could lead to data breaches, denial of service, or complete control over the Kubernetes environment. Organizations using k8sGPT for automated remediation should immediately upgrade to version 0.4.32 or later.

Recommendation

Upgrade k8sGPT to version 0.4.32 or later to patch the vulnerability (reference: Affected versions).
Implement additional validation of Deployment objects before applying them to the cluster to prevent malicious configurations (reference: Overview).
Deploy the Sigma rule provided to detect attempts to create privileged containers or mount sensitive host paths (reference: Sigma rule).
Monitor Kubernetes audit logs for suspicious activity related to Deployment object modifications (reference: Attack Chain).

FlowiseAI AirtableAgent Remote Code Execution via Prompt Injection

hello@craftedsignal.io — Thu, 16 Apr 2026 21:43:57 +0000

FlowiseAI is susceptible to a remote code execution (RCE) vulnerability within the AirtableAgent function. This function, designed to retrieve and process datasets from Airtable.com, is flawed due to the lack of input sanitization. Specifically, user-supplied input is directly incorporated into a prompt template, which is then used to generate Python code executed by Pyodide. By injecting malicious payloads into the prompt, an attacker can bypass the intended behavior of the language model and execute arbitrary Python code, leading to complete system compromise. The vulnerability resides in AirtableAgent.ts and is triggered when the input variable, containing user-supplied data, is passed to the LLMChain without proper validation.

Attack Chain

An attacker crafts a malicious payload containing a prompt injection designed to execute arbitrary code.
The attacker submits the crafted payload via the FlowiseAI application to the AirtableAgent function.
The payload is passed into the input variable without sanitization and incorporated into the prompt template within systemPrompt.
The LLMChain uses the crafted prompt, including the injected code, to generate a pythonCode string.
The generated pythonCode string, containing the malicious code, is passed to the pyodide.runPythonAsync() function.
Pyodide executes the malicious Python code, leading to remote code execution on the FlowiseAI server.
The attacker gains control of the FlowiseAI instance, potentially accessing sensitive data or pivoting to other systems on the network.

Impact

Successful exploitation of this vulnerability allows for complete remote code execution on the FlowiseAI server. This could lead to the compromise of sensitive data stored within Airtable datasets, as well as the potential for lateral movement to other systems on the network. The lack of input validation opens the door to attackers using prompt injection to bypass security measures and gain unauthorized access.

Recommendation

Apply input sanitization and validation to the input variable within the AirtableAgent function in AirtableAgent.ts before it is incorporated into the prompt template.
Implement strict output filtering on the pythonCode generated by the LLMChain to prevent the execution of potentially malicious code.
Deploy the Sigma rule to detect prompt injection attempts targeting the AirtableAgent function.
Regularly audit and update FlowiseAI dependencies, including Pyodide and Pandas, to address any known security vulnerabilities.

The server binds to 127.0.0.1:7337 and serves requests without requiring authentication unless ENGRAM_API_TOKEN is explicitly set.
A developer visits a malicious website in their browser.
The malicious website crafts a cross-origin request to 127.0.0.1:7337 due to the Access-Control-Allow-Origin: * header.
A GET request to /query or /stats is sent, exfiltrating the local knowledge graph, including function names, file layout, and recorded decisions/mistakes.
A POST request to /learn is sent with a crafted prompt-injection payload, exploiting the lack of Content-Type: application/json enforcement.
The injected payload is written as mistake/decision nodes in the knowledge graph.
The user’s AI coding agent is persistently reminded of the injected payload on every future session and file edit, leading to compromised code generation and execution.

Impact

Successful exploitation of this vulnerability could lead to the compromise of sensitive developer data, including internal function names, file layouts, and coding decisions, allowing attackers to gain insights into the target’s projects. Furthermore, the injection of persistent prompt-injection payloads can lead to the ongoing corruption of the user’s AI coding agent, potentially causing the generation of flawed or malicious code. While the exact number of affected users is unknown, any developer using a vulnerable version of engramx is susceptible to this attack.

Recommendation

Upgrade to engramx@2.0.2 or later to apply the remediation measures outlined in the advisory.
If upgrading is not immediately feasible, do not run engram server or engram ui as a workaround.
If engram server must be run, set ENGRAM_API_TOKEN to a long random value and terminate the server before browsing the web (as noted in the advisory).
Deploy the Sigma rule “Detect engramx API access without authentication” to identify potentially unauthorized access attempts to the engramx API.
Monitor network connections to port 7337 on localhost, filtering for unexpected processes initiating connections.
