FKIE_CVE-2026-48765

Vulnerability from fkie_nvd - Published: 2026-08-11 21:17 - Updated: 2026-09-09 20:46
Severity
9.9 (Critical) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:L
Summary
TypeBot is a chatbot builder tool. Versions prior to 3.17.0 allow a low-privilege read collaborator to extract a workspace OAuth `credentialsId` from a readable bot configuration and then overwrite that credential through `handleUpdateOAuthCredentials()` by supplying an attacker-controlled writable `workspaceId`. The update path validates only the attacker-supplied workspace and then updates the credential record by global `id` alone, while also rewriting the credential's `workspaceId`. This allows cross-workspace OAuth credential takeover and reassignment. Version 3.17.0 patches the issue.
