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 these unauthenticated requests as the local development user, exposing the hosted Inspector and related API endpoints 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 Neotoma application (versions >= 0.6.0 and < 0.11.1). The vulnerability arises because the app treats certain reverse-proxied requests received over a loopback socket without Bearer tokens as local, allowing unauthenticated access. This results in the REST authentication middleware granting access as the local development user, making sensitive API surfaces reachable without authentication. The vulnerability is classified under CWE-288 (Authentication Bypass Using Alternate Path or Channel) and CWE-306 (Missing Authentication for Critical Function). It has a CVSS 4.0 base score of 6.9 (medium severity). The issue is resolved in Neotoma version 0.11.1.
Potential Impact
Unauthenticated attackers can access the hosted Inspector and related API endpoints as the local development user, bypassing authentication controls. This exposure could allow unauthorized access to sensitive application functionality and data. There are no known exploits in the wild at this time.
Mitigation Recommendations
Upgrade Neotoma to version 0.11.1 or later, where this authentication bypass vulnerability is fixed. Patch status is confirmed by the vendor's advisory indicating the fix in 0.11.1. No additional mitigations are specified or required once the update is applied.
