DataHub Image Retrieval SSRF Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2026-50775

DataHub is typically deployed as a data management or integration platform which often acts as an externally reachable web-based service or API endpoint, increasing the likelihood of exposure to internet-based requests that can trigger server-side resource retrieval.

Horizon Alert

Summary of the vulnerability and why it matters

A critical vulnerability has been identified in DataHub, a data management platform, allowing remote attackers to potentially execute arbitrary code. This issue stems from how the system handles image retrieval from specific web addresses, which, if crafted maliciously, could lead to unauthorized actions on the server. The primary concern is to confirm if this specific technology is in use and assess any potential exposure.

Issue: Code execution risk in data management software.
Why remember: Affects systems handling data access.
Executive takeaway: Confirm use and assess exposure.

Attack Path

How an attacker could exploit the issue

An unauthenticated attacker can exploit this vulnerability by tricking the server into retrieving an image from a URL they control. Since the server does not properly handle or return errors from this image retrieval process, it creates an opportunity for the attacker to potentially achieve arbitrary code execution.

No authentication required.
Server retrieves a crafted image URL.
Leads to arbitrary code execution.

Live Threat

Current exploitation, exposure, and threat context

A blind server-side request forgery (SSRF) vulnerability in DataHub could allow an unauthenticated remote attacker to compromise system integrity. When DataHub attempts to retrieve an image from a malicious URL, the lack of direct error reporting might be exploited for further attacks. This could lead to unauthorized access or manipulation of internal network resources when the service is exposed externally and configured to fetch external content.

Internal network access and data.
Crafted URLs trigger server requests.
Potential for arbitrary code execution.

Operational Fix

Recommended remediation, mitigation, and detection steps

This blind SSRF vulnerability in DataHub requires immediate attention from the platform or infrastructure team responsible for its deployment and security. The first step is to identify all instances of DataHub, confirm their accessibility and business criticality, and then assign ownership for remediation planning.

Platform/Infrastructure teams own this.
Verify DataHub reachability and criticality.
Plan remediation based on risk exposure.

Frequently asked questions

What is DataHub and how is it used?

DataHub is a data management and integration platform. Organizations use it to streamline data workflows, connect various information sources, and provide a unified interface for data access. Because it often manages connections to external resources or web services, it frequently acts as an API endpoint or a web-based portal to process data requests.

What does CWE-918 mean in the context of CVE-2026-50775?

CWE-918 refers to Server-Side Request Forgery (SSRF). In this specific vulnerability, the application is tricked into making unauthorized requests to a location chosen by an attacker. Because this is a 'blind' SSRF, the server performs the request but does not return the response or errors to the attacker, which obscures the activity while still allowing the attacker to leverage the server to execute arbitrary code.

How does an attacker trigger this vulnerability?

An unauthenticated attacker triggers this by providing a crafted URL to the image retrieval function within DataHub. When the server processes this URL, it initiates an unintended request to the attacker's target. It is important to note that this process does not rely on valid user credentials; the simple act of the server attempting to fetch the malicious resource is sufficient to set the attack in motion.

Is my DataHub instance at risk?

According to Halo Surface Signal, risk depends on accessibility. If your DataHub deployment functions as an externally reachable web service or API, it is more likely to be targeted by internet-based requests. Systems that are restricted to internal networks or do not permit the server to make arbitrary external requests for image retrieval may have a reduced likelihood of successful exploitation.

What should I do first to address CVE-2026-50775?

Your first step is to locate all active DataHub instances within your environment. Once identified, evaluate whether these instances are accessible from the internet and determine their overall business criticality. After confirming the footprint of the software, coordinate with your infrastructure or platform management teams to prioritize these systems for remediation planning.
