CVE-2026-45577: CWE-288: Authentication Bypass Using an Alternate Path or Channel in markmhendrickson neotoma
Neotoma versions from 0.6.0 up to but not including 0.11.1 have an authentication bypass vulnerability. The application can mistakenly treat public reverse-proxied requests received over a loopback socket without a Bearer token as local requests. This causes the REST authentication middleware to resolve unauthenticated requests as the local development user, exposing the Inspector and related API without requiring credentials. This issue is fixed in version 0.11.1.
AI Analysis
Technical Summary
CVE-2026-45577 is an authentication bypass vulnerability in the markmhendrickson Neotoma application affecting versions 0.6.0 through 0.11.0. The flaw arises because the application treats certain reverse-proxied requests received over a loopback socket without Bearer tokens as local, allowing unauthenticated access to privileged API endpoints. This effectively allows an attacker to access the hosted Inspector and related API surfaces without credentials. The vulnerability is identified as CWE-288 (Authentication Bypass Using an Alternate Path or Channel) and CWE-306 (Missing Authentication for Critical Function). The issue is resolved in version 0.11.1.
Potential Impact
Unauthenticated attackers can gain access to the local development user context and reach the Inspector and related API endpoints without credentials. This could lead to unauthorized access to sensitive application functionality and data exposed via these APIs. The CVSS 4.0 base score is 6.9 (medium severity), reflecting network attack vector, low complexity, no privileges required, no user interaction, and limited confidentiality impact.
Mitigation Recommendations
Upgrade Neotoma to version 0.11.1 or later, where this authentication bypass vulnerability is fixed. Since the vendor advisory confirms the issue is resolved in 0.11.1, applying this official fix is the recommended remediation. Patch status is confirmed by the vendor advisory statement. No other mitigations are indicated.
