CVE-2026-48765 baptisteArno CVE debrief

Who should care

Defenders responsible for TypeBot deployments, particularly those with low-privilege read collaborators, should assess exposure and prioritize upgrading to version 3.17.0 or later.

Why it matters

CVE-2026-48765 allows low-privilege read collaborators in TypeBot to extract and overwrite workspace OAuth credentials, enabling cross-workspace credential takeover and reassignment. Defenders should prioritize verifying and upgrading to TypeBot version 3.17.0 or later, and review workspace OAuth credentials for potential exposure.

• Credential takeover and reassignment across workspaces
• Potential unauthorized access to sensitive data
• Need for verification of TypeBot version and workspace OAuth credentials
• Priority on upgrading to version 3.17.0 or later

Technical summary

TypeBot versions prior to 3.17.0 contain a vulnerability allowing low-privilege read collaborators 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. The vulnerability is patched in version 3.17.0.

Defensive priority

Defenders should prioritize verifying and upgrading to TypeBot version 3.17.0 or later, and review workspace OAuth credentials for potential exposure.

Recommended defensive actions

• Verify TypeBot version and upgrade to 3.17.0 or later
• Review workspace OAuth credentials for potential exposure
• Restrict access to bot configurations and OAuth credentials
• Confirm whether affected TypeBot deployments exist in managed environments and assign an owner for follow-up
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Check relevant monitoring, detection, and logs for exposed assets that need extra review

Evidence notes

Evidence from the CVE record and source references indicates a critical vulnerability in TypeBot versions prior to 3.17.0, allowing low-privilege read collaborators to extract and overwrite workspace OAuth credentials.
