CVE-2026-62865Public exploitNetwork attack vectorHinoki check available

Server file read via unchecked attachment path

Published Aug 25, 2026 · Updated Aug 26, 2026

Path traversal in Typebot before 3.18.0 allows remote authenticated users to read server files through Send Email attachments. The parseAttachments helper passes any value outside the application base URL to Nodemailer as a filesystem path while local file access remains enabled. A registered user can publish a bot with attacker-controlled attachment and recipient variables, exposing any file readable by the server process without administrator access or victim interaction.
