Command Injection in Coolify Database Backup

Publication date: 2026-07-06

Last updated on: 2026-07-06

Assigner: GitHub, Inc.

Description

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. From 4.0.0-beta.451 through 4.0.0-beta.470, database backup handling for MongoDB collection names did not fully validate shell metacharacters, allowing a highly privileged attacker who can configure backup inputs to inject commands. This issue is fixed in version 4.0.0-beta.471.

Attack-Flow Graph

Executive Summary

This vulnerability exists in Coolify versions from 4.0.0-beta.451 through 4.0.0-beta.470. It involves the handling of database backups for MongoDB collection names, where the software did not fully validate shell metacharacters. This flaw allows a highly privileged attacker, who has the ability to configure backup inputs, to inject arbitrary commands via these unvalidated shell metacharacters.

Impact Analysis

The vulnerability can allow a highly privileged attacker to execute arbitrary commands on the system by injecting shell commands through the backup configuration inputs. This could lead to unauthorized actions affecting the integrity and confidentiality of the database backups, potentially compromising the system or data managed by Coolify.

Mitigation Strategies

To mitigate this vulnerability, you should upgrade Coolify to version 4.0.0-beta.471 or later, where the issue with database backup handling for MongoDB collection names has been fixed.
