Vulnerability in Prolix-Oc Lumiverse
CVE-2026-44443
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.
