Lightdash is an open source business intelligence platform. In affected versions through 0.3213.0, the dbt Cloud webhook POST /api/v1/projects/{projectUuid}/dbt-cloud/webhook has no authentication middleware or signature validation. In packages/backend/src/controllers/projectController.ts, testWebhook() accepts accountId and runId from a job.run.completed request and passes them to createPreviewWithExplores() in packages/backend/src/services/ProjectService/ProjectService.ts. These unsanitized values are interpolated into the server-side dbt Cloud API URL, which is requested with the victim project's API key in the Authorization header. Path traversal through accountId changes the requested path on cloud.getdbt.com without changing its host, so the credential-bearing request reaches an attacker-influenced path on that fixed host. The advisory claims API-key theft, but the supplied evidence does not establish that the attacker can observe the Authorization header. The unauthenticated webhook also allows preview creation. The target must be a dbt Cloud IDE project and the attacker must know its projectUuid; the UUID is not enumerable but can be discovered in shared or multi-tenant contexts. Version 0.3214.0 fixes identifier path traversal and verifies webhook HMAC signatures only when a secret is configured; without a secret, unsigned webhooks continue to be processed.

EG Risk is EchelonGraph's 0–100 priority score. It fuses impact severity (EG Severity, the CVSS base score, never the KEV-floored or EPSS-lifted EG Score) with real-world exploitation and automatability, under weights EchelonGraph set by hand, so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner.

Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".
