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processed.","score":8.3,"severity":"high","published":"2026-10-29T21:19:12.542Z","modified":"2026-10-29T21:19:12.542Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"lightdash","name":"lightdash","platforms":[],"versions":[{"version":"< 0.3214.0","status":"affected"}],"cpes":[],"source":"GitHub_M","url":"https://www.cve.org/CVERecord?id=CVE-2026-61654"}],"remediation":[],"references":["https://github.com/lightdash/lightdash/security/advisories/GHSA-r4xc-vwqr-3252","https://github.com/lightdash/lightdash/pull/24587","https://github.com/lightdash/lightdash/commit/8d1d9bb6804bbea66a7bdf1b9b00092665382f14","https://github.com/lightdash/lightdash/releases/tag/0.3214.0"],"sources":[{"name":"CVE","id":"CVE-2026-61654","modified":"2026-10-29T21:19:12.542Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-61654"}],"assessments":[{"source":"GitHub_M","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N","score":8.3}],"sourceAffected":[],"observedAt":"2026-10-29T21:56:33.975Z","kev":{"status":"not-listed","checkedAt":"2026-10-31T13:30:33.323Z"},"coverage":[{"source":"NVD","status":"no-result","checkedAt":"2026-10-29T22:00:36.157Z","attemptedAt":"2026-10-29T22:00:36.157Z"},{"source":"GHSA","status":"no-result","checkedAt":"2026-10-29T22:00:34.772Z","attemptedAt":"2026-10-29T22:00:34.772Z"},{"source":"EUVD","status":"available","checkedAt":"2026-10-29T22:00:35.782Z","attemptedAt":"2026-10-29T22:00:35.782Z"},{"source":"EPSS","status":"no-result","checkedAt":"2026-10-29T22:00:34.641Z","attemptedAt":"2026-10-29T22:00:34.641Z"}],"evidence":[{"source":"ENISA EUVD","id":"EUVD-2026-113396","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-113396","modified":"Oct 29, 2026, 9:19:12 PM","score":8.3,"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N","checkedAt":"2026-10-29T22:00:35.782Z"}],"aiSummary":{"text":"Lightdash versions through 0.3213.0 have an unauthenticated dbt Cloud webhook with path injection, potentially leaking API key.
