SQL Injection in Kestra Docker Leads to Remote Code Execution

Publication date: 2026-04-03

Last updated on: 2026-04-13

Assigner: GitHub, Inc.

Description
Kestra is an open-source, event-driven orchestration platform. Prior to version 1.3.7, Kestra (default docker-compose deployment) contains a SQL Injection vulnerability that leads to Remote Code Execution (RCE) in the following endpoint "GET /api/v1/main/flows/search". Once a user is authenticated, simply visiting a crafted link is enough to trigger the vulnerability. The injected payload is executed by PostgreSQL using COPY ... TO PROGRAM ..., which in turn runs arbitrary OS commands on the host. This issue has been patched in version 1.3.7.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

Kestra is an open-source, event-driven orchestration platform. Prior to version 1.3.7, the default docker-compose deployment of Kestra contains a SQL Injection vulnerability in the endpoint "GET /api/v1/main/flows/search". Once a user is authenticated, simply visiting a specially crafted link can trigger this vulnerability. The injected SQL payload is executed by PostgreSQL using the COPY ... TO PROGRAM ... command, which allows arbitrary operating system commands to be run on the host machine.

This vulnerability has been fixed in Kestra version 1.3.7.

Impact Analysis

This vulnerability can have severe impacts because it allows an authenticated user to execute arbitrary operating system commands on the host running Kestra. This means an attacker could potentially take full control of the system, leading to data theft, data loss, service disruption, or further compromise of the network.

Mitigation Strategies

The vulnerability has been patched in Kestra version 1.3.7. The immediate step to mitigate this vulnerability is to upgrade Kestra to version 1.3.7 or later.
