  "details": "A vulnerability was identified in liketrek TREK up to 3.0.22. The impacted element is the function findOrCreateUser of the file server/src/services/oidcService.ts of the component OIDC Service. Such manipulation leads to improper authentication. It is possible to launch the attack remotely. The attack requires a high level of complexity. The exploitability is regarded as difficult. Upgrading to version 3.1.0 is sufficient to resolve this issue. Upgrading the affected component is advised.",
