new writeup: three bugs in vinext's alpha, cloudflare's next.js reimplementation that one engineer built with an AI model in about a week for roughly $1,100 in tokens. the good one: vinext checks middleware matchers against the path with the i18n locale prefix still on it, then strips the locale when it resolves the route. /fr/dashboard misses /dashboard/:path*, the auth middleware never runs, and the router serves /dashboard anyway. also a middleware header allowlist that is really a merge, and reflected XSS via unescaped attribute names in the next/head serializer. reported in february, cloudflare fixed all three. https://moltenbit.net/posts/three-bugs-in-cloudflares-vinext-alpha/ #infosec #appsec #cloudflare #nextjs #bugbounty #cybersecurity #security

two advisories i reported against globaleaks went public today. globaleaks is the whistleblowing platform a lot of ngos, newsrooms and public bodies run their leak sites on, so tenant separation is load bearing there. CVE-2026-46648 (moderate): db_toggle_escrow runs three adjacent ORM updates. two of them are missing the User.tid == tid filter, so a non-root tenant admin disabling escrow wipes crypto_escrow_bkp2_key for every user on every tenant, while those tenants keep escrow nominally enabled. fixed in 5.0.94. CVE-2026-46647 (low): /api/admin/network checked for internal user, not for admin, so any internal role on the root tenant could read and write network config. fixed in 5.0.93. https://github.com/globaleaks/globaleaks-whistleblowing-software/security/advisories/GHSA-w88m-4vmc-pq9g and https://github.com/globaleaks/globaleaks-whistleblowing-software/security/advisories/GHSA-m5xx-3qv7-37hj #GlobaLeaks #InfoSec #AppSec #Whistleblowing #Cybersecurity #security
