The editor is about to be opened to strangers: a post on Reddit and a guest access (#428). nginx served the whole workspace and ran every PHP file in it, the API let anybody guess passwords as fast as they liked, and one account could fill the disk. - nginx (shared web stack, outside this repo, backup in /root/config-backup-20261015/) hands out only the two pages, dist/, public/brand/, the uploads by kind and ending, and api/index.php. Everything else under /feuerwerk/ is a 404. - PHP behind it has display_errors off and no X-Powered-By. Plain HTTP forwards to HTTPS, the API refuses it. - Headers: a Content-Security-Policy without inline code or eval, nosniff, frame-ancestors, HSTS, Referrer-, Permissions-, COOP, CORP. - vite.config.ts writes the same policy into the built pages, so CI runs the whole suite under it. Pixi gets by without eval through pixi.js/unsafe-eval. The page CSS left its inline style for a file. - The harness fails a module for anything the policy refuses, from Chrome's log and from the page's securitypolicyviolation event. - LoginThrottle: five wrong passwords from one address within 15 minutes, and it gets 429 until 15 minutes after the last of them. The address is the last X-Forwarded-For entry, the Brandmauer's own. - Quota: 1 GB per account for uploads, projects and snapshots. Only a write that grows the account is refused (413). Admins have no limit. - A write whose Sec-Fetch-Site says another site is refused (403). - The session cookie carries Secure, nginx passes HTTPS on. - showFailure puts the message in as text, not as HTML. - Every PHP script outside api/ stops unless it runs on the command line. - The video worker sees the checkout read-only and can only write data/videos. No capabilities, 2 GB and 256 processes at most. - tests/php/rights.test.php runs the API under php -S on a scratch directory and asks every route as signed out, owner, stranger and admin. A route named in api/index.php but missing in the matrix fails it. limits.test.php covers the brake and the quota. Findings: - tmp/ was readable from outside, with 79 copies of project files. Closed on 15.10. at 20:02 with chmod 750. The log back to 11.10. shows only our own requests. - Port 8080 is bound on 0.0.0.0, so the LAN could reach nginx past the Brandmauer. Left as it is: the web stack is not this project's. - npm audit finds nothing in what is shipped. Dev tools (vitest, brace-expansion, source-map-js) have advisories, not touched here. Tests: check 313 files / 4843 tests. PHP limits 21, rights 60, accounts 56, snapshots 15, releases 20, files 46 (videos 50/51, no ffmpeg in the web container). e2e on stein2, atx was off: 34+38+41 197/198, the one red check (a click in 41) passes with 41 alone, 27/27. 67 misses frames at 1080p on stein2 with and without this. Path list from outside: 10 served, 26 refused. ZAP baseline against the live site: nothing High or Medium under /feuerwerk/. Counter-checks: rights.test.php without the cross-site guard, the quota, the brake, the admin check of users, or with an undocumented route fails each time. A policy without wasm-unsafe-eval fails e2e 41 with the harness's own CSP line. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# The video worker on stein2 (#402), a compose project of its own beside the web stack:
|
|
#
|
|
# docker compose -f tools/video/compose.yml up -d
|
|
#
|
|
# It works on the checkout itself (the folder nginx serves), as www-data like the PHP container, so
|
|
# the files it writes belong to the same user. It needs no network.
|
|
#
|
|
# ffmpeg reads files strangers uploaded, so the container is kept small (#427): the checkout is
|
|
# read-only and only data/videos can be written, there are no capabilities, and memory and processes
|
|
# have a ceiling. A broken decoder could fill that one folder, not change the API or the pages.
