nexxo	f8874f32ea	Put customer instances on their own domain, and say which domains are ours ... ── The zone ──────────────────────────────────────────────────────────────── A fresh install now addresses customer instances under clupilot.cloud rather than clupilot.com. Not branding: a Nextcloud is third-party software that strangers sign in to, and on the same registrable domain as the portal it shares cookie scope, document.domain and CAA with it. The same reason googleusercontent.com and vercel.app exist. Existing installations keep whatever the console says — the zone has been a setting all along. `clupilot:check-zone <zone>` reports what a change would touch before anything is touched: the DNS records, the monitoring targets, the certificates and Nextcloud's trusted_domains all carry the old name and the setting reaches none of them. With no instances in service it says so and stops. Changing it later is a migration with an outage, and the command says that too. ── Which addresses are ours ──────────────────────────────────────────────── A new public page at /sicherheit: the domains that belong to us, the rule for reading an address bar, what we never do, and — the part that matters — what to do if you have already typed your password into a copy of our sign-in form. Change it, end every other session, change it wherever else you use it, tell us. In that order. Reachable without an account, deliberately: somebody who has just given their password away is signed in nowhere, and the page they need cannot be behind the thing they lost. Linked from the three places a person is when the question comes up: every mail footer (the mail is the vector), the sign-in form (this is the page a phishing kit copies, so the real one says which host you are on), and the site footer. The domain list is DERIVED from configuration and keyed by what each domain is for. A list typed into a page would eventually tell a customer that a phishing domain is one of ours, or that one of ours is not — the same two-sources-of-truth failure that had the price sheet promising an address on a domain the company does not own. The operator console is deliberately absent from it: naming it on a public page tells an attacker where to aim. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-07-29 16:03:13 +02:00
nexxo	2609393e3a	Recognise the devices an account signs in from, and warn about a new one ... Sessions lived in Redis, where they cannot be enumerated — one key per session, no index by user — so "where am I signed in" and "end that one" were not answerable at all. The database driver keeps a row per session and makes ending one a delete. It costs every currently signed-in person one forced sign-in, once, which is why it is happening now rather than later. The warning is only worth anything if it is rare, so the two obvious signals are deliberately not used. Not the IP: it changes on every train, every café, every mobile handover, and behind a VPN it is not theirs to begin with. Not the user-agent: Chrome ships every four weeks and the string changes each time, which would be twelve warnings a year per customer, describing nothing. A device is a long-lived signed cookie holding a random token, and nothing else is consulted. The honest cost — cleared cookies, a private window, a second browser — is written into the mail itself, because a reader who thinks the warning is wrong stops reading the next one. Three things the tests found or hold: The first device on an account is new and must not warn. Replying to somebody creating an account by telling them they signed in from a new device is noise on the one message that has to stay worth reading. token_hash was globally unique, and the shared-browser test failed on it. Two people on one machine share one cookie and must each own a device row against it; the obvious repair — issue a fresh token for the second — would orphan the first person's row and warn them about their own desk. Unique is now per identity. Recording a device may never block a sign-in. A safeguard that locks the owner out when it breaks has stopped being one, so the listener logs and swallows, and a test drops the tables to prove it. Sessions are linked by a uuid carried inside the session payload rather than by the session id, which Laravel rotates on every sign-in and every regenerate(). Laravel's own sessions.user_id cannot carry the link either: it is filled from the default guard, while operators and customers are two guards and two tables (R21) — operator 1 and customer 1 would each be offered the other's sessions. Also lands the shared mail layout the rest of the templates will use: tables and inline styles for Outlook, no image and no web font because half of all clients block remote content, and the button in --accent-active rather than the brand orange, which is 2.9:1 against white. Not tagged: the session list is not built yet, and without a tag no server can install this. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-07-28 23:28:34 +02:00
