CVE-2026-67449: Portabase path traversal in TUS upload webhook handler

CVE-2026-67449 · Severity: critical · CVSS 9.8 · Published 2026-11-11

Portabase is a database backup tool that stores encrypted backups in the cloud. Prior to version 1.21.2, an attacker could bypass security controls on the file upload endpoint to overwrite critical encryption keys, allowing them to decrypt all stored backups without authentication. This compromises the confidentiality of all backed-up databases.

How to fix

Fixed in: 1.21.2

Technical details

A path traversal vulnerability in the TUS upload webhook handler (app/api/tus/hooks/route.ts) allowed unauthenticated attackers to manipulate the X-File-Path header to write arbitrary files into the private data directory, specifically the AES-256-GCM master key at /data/private/keys/master_key.bin. The fix validates file paths against a regex allowlist, enforces database-backed authorization checks, and blocks direct external access to the endpoint via Nginx rules.
