Published May 26, 2026CWE-362EPSS 0.18%

Overview

CVE-2026-44443 is a medium-severity vulnerability. It was published on May 26, 2026 and has a CVSS 3.1 base score of 4.8 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.8, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

Lumiverse is a full-featured AI chat application. Prior to 0.9.7, consumeNonce() only checks that the module-level variable is set and unexpired. It does not validate any value from the incoming HTTP request or bind the nonce to the admin's session. If the admin's auth.api.signUpEmail() call fails before the before hook fires (e.g. BetterAuth rejects a duplicate email at the validation layer), the nonce is set but never consumed. Any POST /api/auth/sign-up/email request that arrives during the remaining window registers successfully regardless of who sent it. An attacker who can observe or predict when the admin is creating users (must be a dupplicate user) can race the 10-second window to register an unauthorized account. This vulnerability is fixed in 0.9.7.

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.
