High impact if exploited, but EPSS currently rates exploitation as unlikely (0.27%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Budibase is a low code platform for creating internal tools, workflows, and admin panels. In 3.31.5 and earlier, a path traversal vulnerability in the PWA (Progressive Web App) ZIP processing endpoint (POST /api/pwa/process-zip) allows an authenticated user with builder privileges to read arbitrary files from the server filesystem, including /proc/1/environ which contains all environment variables — JWT secrets, database credentials, encryption keys, and API tokens. The server reads attacker-specified files via unsanitized path.join() with user-controlled input from icons.json inside the uploaded ZIP, then uploads the file contents to the object store (MinIO/S3) where they can be retrieved through signed URLs. This results in complete platform compromise as all cryptographic secrets and service credentials are exfiltrated in a single request.
