{"id":"CVE-2026-113788","kind":"vulnerability","aliases":["CVE-2026-113788"],"related":[],"title":"Lagoon Kubernetes platform: ssh service flaw lets logged-in users run code","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.","summary":"Lagoon is an application delivery platform for Kubernetes, and its core ssh service has a flaw that allows arbitrary code execution.
