CVE-2026-48765Public exploitNetwork attack vectorHinoki check available

Authenticated OAuth credential takeover via missing binding

Published Aug 11, 2026 · Updated Aug 11, 2026

Authorization bypass in Typebot before 3.17.0 allows remote authenticated users to take over cross-workspace OAuth credentials. handleUpdateOAuthCredentials validates only the supplied workspace, then updates the credential by its global credentialsId and rewrites its workspaceId without verifying ownership. Exploitation requires read access to a victim bot, write access to another workspace, and a valid OAuth code; affected integrations then use attacker-controlled tokens.
