Overview

CVE-2026-48765 is a critical-severity vulnerability. It was published on August 11, 2026 and has a CVSS 3.1 base score of 9.9 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.9, rated CRITICAL. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
