pgAdmin 4 Import Export Tool Query Bypass Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.4)

CVE-2026-116241

pgAdmin is a database management tool typically deployed in internal, administrative, or developer-focused environments to access database servers. While it provides a web interface that can be exposed to the internet, it is not inherently designed for public-facing use by general internet users, making direct exposure less common than typical public-facing web applications or edge services.

Horizon Alert

Summary of the vulnerability and why it matters

A vulnerability in the pgAdmin 4 Import/Export Data tool could allow an attacker to execute commands on the pgAdmin server with the operating system's privileges. This issue arises from how the tool processes database query exports, potentially bypassing security checks when certain quoting and escaping configurations are used, and it affects users with ordinary database roles.

A tool flaw allows unauthorized command execution.
Unpatched systems risk unauthorized server access.
Confirm relevance and exposure for this tool.

Attack Path

How an attacker could exploit the issue

An attacker with limited database access can exploit a flaw in pgAdmin 4's data export feature. By manipulating query syntax to bypass a security check, they can trick the tool into executing arbitrary operating system commands on the server running pgAdmin. This can lead to significant compromise of the server and its data.

Requires less than administrator access.
Exploits data export tool with malformed queries.
Allows remote code execution on the host.

Live Threat

Current exploitation, exposure, and threat context

When a database role can disable `standard_conforming_strings`, an attacker could potentially execute arbitrary operating-system commands on the pgAdmin host by crafting a malicious query. This could affect the pgAdmin service and the underlying operating system.

Arbitrary command execution on the host.
Exploiting a parsing difference in SQL.
Compromise of the host system.

Operational Fix

Recommended remediation, mitigation, and detection steps

The pgAdmin platform team or the application owners are likely responsible for addressing this vulnerability, as it affects the Import/Export Data tool within pgAdmin 4. The immediate first step is to identify all instances of pgAdmin 4, determine their reachability and criticality, and assign an owner for remediation planning.

Assign ownership to platform or application teams.
Verify pgAdmin 4 instances and exposure.
Plan vendor coordination or upgrade.

Frequently asked questions

What is pgAdmin 4 and what is it used for?

pgAdmin 4 is a popular open-source administration and development platform for PostgreSQL databases. It provides a graphical web interface that allows database administrators and developers to manage server objects, run SQL queries, and perform data import or export tasks efficiently from a centralized browser-based console.

How does this vulnerability work in CVE-2026-116241?

This issue is a form of OS Command Injection, classified as CWE-78. The Import/Export tool attempts to safely wrap user queries, but a parsing flaw allows an attacker to hide malicious commands within specific SQL syntax. When the tool processes these queries, it inadvertently escapes the safety wrapper, causing the server to execute unauthorized operating system commands instead of just processing database data.

Do I need administrator access to trigger this bug?

No. The vulnerability does not require administrative database privileges. Because the Import/Export feature is available to ordinary database roles by default, an attacker with basic, non-administrative access to the database can potentially trigger the flaw. Simply having the ability to initiate a data export and manipulate the underlying query string is sufficient to attempt the exploit.

Is my pgAdmin 4 instance at risk?

Halo Surface Signal suggests that pgAdmin is typically used in internal or developer-focused environments, making it less common for these services to face the public internet directly. However, if your specific deployment is reachable from outside your network, the risk increases significantly. You should audit your environment to verify if your pgAdmin instances are internet-facing or restricted to internal users.

When should I take action to remediate this?

You should begin planning your response immediately. Start by identifying all active instances of pgAdmin 4 within your infrastructure to assess their configuration and reachability. Once identified, assign ownership to the appropriate technical team to coordinate a version upgrade, as this flaw affects all versions of pgAdmin 4 prior to 9.19.
