CVE-2026-72772 Vulnerability Summary

CVE-2026-72772: n8n before 2.32.1 (and before 2.31.5) is vulnerable to account takeover via the Token Exchange Embed Login feature. When a validly-signed incoming token was matched to a local account by its email claim, the service did not verify that the email claim was verified, nor that the trusted key's permitted role ceiling covered that account. As a result, anyone able to obtain a token accepted by a configured trusted key (for example, a trusted issuer emitting unverified email addresses) could authenticate as any existing user and gain full account control. This issue only affects instances where the embed login feature is enabled and at least one trusted key source is configured.

Assessing the Risk of CVE-2026-72772

Access Complexity Graph

The exploitability of CVE-2026-72772 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2026-72772

No exploitability data is available for CVE-2026-72772.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2026-72772, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
