Lifecycle Timeline
4DescriptionCVE.org
knowns versions before 0.30.0 contain a path traversal vulnerability in the POST /api/templates/preview endpoint that allows unauthenticated attackers to read arbitrary files. Attackers can supply directory traversal sequences in the templateFile parameter to bypass path restrictions and read sensitive files like credentials and configuration through the JSON response.
AnalysisAI
Path traversal in the knowns template-preview API (versions before 0.30.0) allows unauthenticated remote attackers to read arbitrary server-side files by injecting directory traversal sequences into the templateFile parameter of POST /api/templates/preview, with file contents returned directly in the JSON response. Sensitive targets include credential files, database configuration, and API keys accessible to the knowns process user. …

Vulnerability AssessmentAI
| Exploitation | No special configuration or authentication is required. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 8.7 with vector AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N accurately characterizes the threat: the endpoint requires no authentication and is reachable over the network with no preconditions, delivering high confidentiality impact through a direct file-read primitive. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade knowns to v0.30.0 or later, which introduces the safepath package providing robust path confinement with rejection of traversal sequences, symlink escapes, and platform-specific bypass variants. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Audit your network for all knowns instances and determine exposure scope, particularly internet-facing deployments, using internal asset inventory and network scanning. …
