What is CVE-2026-48765?

TypeBot, a popular chatbot builder tool, is susceptible to an OAuth credential vulnerability where low-privilege users can exploit a bot configuration to hijack workspace OAuth credentials. In versions before 3.17.0, attackers can leverage the handleUpdateOAuthCredentials() function by supplying a writable workspaceId, which allows them to overwrite existing credentials due to inadequate validation processes. This flaw poses a significant risk of unauthorized access to bot configurations and sensitive user data across different workspaces.

Affected Version(s)

typebot.io < 3.17.0
