CVE-2026-48765

Full vulnerability record from the local CVENow database.

Description

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.

      "value": "TypeBot es una herramienta de creación de chatbots. Las versiones anteriores a la 3.17.0 permiten a un colaborador de lectura con bajos privilegios extraer un “credentialsId” de OAuth de un espacio de trabajo de una configuración de bot legible y luego sobrescribir esa credencial a través de “handleUpdateOAuthCredentials()” suministrando un “workspaceId” escribible controlado por el atacante. La ruta de actualización valida solo el espacio de trabajo suministrado por el atacante y luego actualiza el registro de la credencial solo por el “id” global, mientras también reescribe el “workspaceId” de la credencial. Esto permite la toma de control y la reasignación de credenciales OAuth entre espacios de trabajo. La versión 3.17.0 corrige el problema."
