Overview

CVE-2026-45732 is a high-severity vulnerability. It was published on June 23, 2026 and has a CVSS 3.1 base score of 8.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.1, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

n8n is an open source workflow automation platform. Prior to 1.123.43, 2.22.1, and 2.20.7, the OAuth1 and OAuth2 credential reconnect endpoints authorized access using credential:read rather than credential:update. An authenticated user with read-only access to a shared credential could initiate an OAuth reconnect flow and overwrite the stored token material for that credential with tokens bound to an external account they control. Workflows relying on the affected credential would subsequently execute under the attacker's OAuth identity, enabling data exfiltration to attacker-controlled external services and persistent takeover of shared integrations. This vulnerability is fixed in 1.123.43, 2.22.1, and 2.20.7.

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.
