CVE-2026-27702Public exploitNetwork attack vector

Authenticated server code execution via unsafe eval

Published Feb 25, 2026 · Updated Feb 25, 2026

Code injection in Budibase Cloud before 3.30.4 allows remote authenticated users to execute arbitrary JavaScript on the server. inMemoryView.ts concatenates a user-controlled view map function into an assignment string and passes it to eval() without sanitizing injected JavaScript syntax. Any authenticated cloud account can reach the path; self-hosted deployments use native CouchDB views, while successful execution exposes pod secrets and tenant database access.
