Remote Code Execution in Lagoon Kubernetes Platform

Publication date: 2026-10-21

Last updated on: 2026-10-23

Assigner: GitHub, Inc.

Description

Lagoon is an application delivery platform for Kubernetes. Versions prior to 2.33.1 have a vulnerability in the `ssh` service in Lagoon core that would allow an attacker to execute arbitrary code which could lead to, among other things, elevated administrative permissions. It is mitigated by the fact that an attacker must have a Lagoon user account. Exploitation may be detected by checking the container logs of the `ssh` service for: `too many arguments`. The vulnerability was fixed in Lagoon v2.33.2, which is included in the `lagoon/lagoon-core` helm chart v1.62.2. As a workaround, the `ssh` service in Lagoon core can be disabled. The `ssh-portal` service and components are not effected and can continue to be used.

Attack-Flow Graph

Executive Summary

CVE-2026-113788 is a critical vulnerability in Lagoon's ssh service that allows remote code execution due to improper neutralization of special elements in OS commands. Attackers with a valid Lagoon user account can exploit this to run arbitrary code and potentially gain elevated administrative permissions.

Detection Guidance

Check the container logs of the ssh service in Lagoon core for the string 'too many arguments'. This may indicate exploitation attempts.

Impact Analysis

This vulnerability allows attackers with a Lagoon account to execute arbitrary code, potentially leading to unauthorized access, data breaches, or system compromise. Exploitation may be detected by checking ssh service logs for 'too many arguments'.

Compliance Impact

This vulnerability allows remote code execution with elevated administrative permissions, which could lead to unauthorized access to sensitive data. For GDPR, this may result in violations of data confidentiality and integrity requirements. For HIPAA, it could compromise protected health information integrity and availability. The high CVSS score (9.4) indicates severe potential impact on compliance.

Mitigation Strategies

Upgrade Lagoon to version 2.33.2 or later, which includes the fix for this vulnerability.
Alternatively, disable the ssh service in Lagoon core as a temporary workaround.
