DescriptionCVE.org

A security flaw has been discovered in liketrek TREK up to 3.0.22. This affects an unknown function of the file server/src/nest/journey/journey-public.controller.ts of the component Public Journey Photo Proxy. Performing a manipulation results in path traversal. The attack can be initiated remotely. The attack's complexity is rated as high. The exploitability is reported as difficult. Upgrading to version 3.1.0 mitigates this issue. It is advisable to upgrade the affected component.

AnalysisAI

Path traversal in the liketrek TREK Public Journey Photo Proxy controller allows remote attackers - without authentication - to read files outside the intended directory on self-hosted instances running version 3.0.22 or earlier. The affected endpoint (server/src/nest/journey/journey-public.controller.ts) fails to adequately sanitize path inputs, exposing server-side files to limited confidentiality disclosure. …

Hypothetical attack flow derived from CVE metadata

Access

Execution
Bypass partial path sanitization logic
Impact
Read arbitrary files accessible to server process

Vulnerability AssessmentAI

Exploitation The target must be running liketrek TREK version 3.0.22 or earlier with the instance network-accessible to the attacker. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 6.3 with AV:N/AC:H/PR:N/UI:N reflects a remotely reachable, unauthenticated attack surface paired with high exploitation complexity - meaning this is not a trivially weaponizable flaw. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An unauthenticated remote attacker sends a crafted HTTP GET request to the TREK Public Journey Photo Proxy endpoint, embedding path traversal sequences (e.g., `../../.env` or URL-encoded equivalents) in the filename or path parameter. If the server's partial validation is bypassed through encoding tricks or specific path structures, the server returns the contents of files outside the media directory - potentially including the application's `.env` file containing database credentials or API keys. …
Remediation The primary remediation is to upgrade liketrek TREK to version 3.1.0, the vendor-released patch available at https://github.com/liketrek/TREK/releases/tag/v3.1.0. … Detailed patch versions, workarounds, and compensating controls in full report.
