{"cve":"CVE-2026-27702","nvd":{"published":"2026-02-25T16:23:26.777","modified":"2026-06-17T10:27:32.633","status":"Analyzed","description":"Budibase is a low code platform for creating internal tools, workflows, and admin panels. Prior to version 3.30.4, an unsafe `eval()` vulnerability in Budibase's view filtering implementation allows any authenticated user (including free tier accounts) to execute arbitrary JavaScript code on the server. This vulnerability ONLY affects Budibase Cloud (SaaS) - self-hosted deployments use native CouchDB views and are not vulnerable. The vulnerability exists in `packages/server/src/db/inMemoryView.ts` where user-controlled view map functions are directly evaluated without sanitization. The primary impact comes from what lives inside the pod's environment: the `app-service` pod runs with secrets baked into its environment variables, including `INTERNAL_API_KEY`, `JWT_SECRET`, CouchDB admin credentials, AWS keys, and more. Using the extracted CouchDB credentials, we verified direct database access, enumerated all tenant databases, and confirmed that user records (email addresses) are readable. Version 3.30.4 contains a patch.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","score":9.0},"cwes":["CWE-94","CWE-20","CWE-95"],"references":["https://github.com/Budibase/budibase/commit/348659810cf930dda5f669e782706594c547115d","https://github.com/Budibase/budibase/pull/18087","https://github.com/Budibase/budibase/releases/tag/3.30.4","https://github.com/Budibase/budibase/security/advisories/GHSA-rvhr-26g4-p2r8"],"products":["budibase:budibase"],"source":"nvd","synced_at":"2026-10-19T22:24:17.937441719+00:00"},"epss":{"cve":"CVE-2026-27702","score":0.00394,"percentile":0.33604,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-rvhr-26g4-p2r8","url":"https://osv.dev/vulnerability/GHSA-rvhr-26g4-p2r8","summary":"Budibase: Remote Code Execution via Unsafe eval() in View Filter Map Function (Budibase Cloud)","modified":"2026-02-25T19:26:58.676004Z","packages":[{"ecosystem":"npm","name":"budibase","purl":"pkg:npm/budibase","ranges":["<3.30.4"],"fixed":["3.30.4"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
