Every upload now starts as "being checked" and is not served to anyone
until a scanner has looked at it. Infected files are quarantined: kept
on disk, unreachable, waiting for an administrator.
The scanner is ClamAV, reached over a socket, streaming the file
wherever it is stored — no temporary copy for an S3 or GCS disk. What
the scanner answers is a fact; what it means for the file is this
installation's setting, so ClamAvScanner knows nothing about settings
and ScanPolicy knows nothing about sockets. Three of clamd's own alert
options are what make a file it could not open come back as an answer
rather than as "OK"; the client maps those to "too large" and
"encrypted" instead of to a threat.
Both policies default to letting files through, marked "not scanned",
which is the product owner's decision: a scanner that cannot answer must
not stop people working. Every such file is logged, and the screens that
say so come with the rest of this work.
Withholding is two rules. A file that is not available drops out of the
scopes that answer "what may this person see" — recipients and the
public listings, never the uploader's own copy. And every route that
puts bytes on the wire asks FileAvailability first: download, thumbnail,
preview, share link, the four public routes and both ends of a zip
build. A share link minted before the scan finishes says the file is
still being checked rather than 404ing.
Not yet here, and coming next: the quarantine screen and its permission,
the notifications, the settings screen, the hourly retry, the backfill
for existing libraries, and the Docker service.
The expired page offers a "send me a new one" button that re-issues the
invitation with no staff member involved. On its own that is reasonable --
the new link goes to the address on the invitation, never to whoever
clicked, so holding a leaked URL gets nobody a working one, and it is the
same shape as a password reset.
What it spent was the operator's expiry window. A link could be renewed
from a dead link, indefinitely, so a window set to 72 hours was only ever
as short as the longest anybody bothered to wait. That matters in the case
expiry is actually for: a link sitting somewhere it should not be -- a
forwarded thread, a shared inbox, a mailbox that changed hands.
So the chain gets a limit: three renewals, then a staff member has to send
a new invitation. The count is carried forward on each renewal rather than
stored per row, which is what makes it apply to the chain; a staff-sent
invitation starts at zero, because sending one is somebody deciding to.
A renewal beyond the limit answers in exactly the same words as a spent,
unknown or revoked token, and sends nothing. Four situations, one sentence:
telling them apart is how this door would become a way to learn which
addresses an installation has invited.
Renewals are now logged, which they were not -- sending and redeeming
already were, and renewing was the one step that moved an invitation along
with nobody behind it and left no trace. The limit bounds how many rows an
anonymous door can write.

An invitation could be sent and never taken back. There was no list of
outstanding ones and no revoke, so the only way to withdraw a link sent to
the wrong address was to let it expire -- and the expired page's own "send
me a new one" button undoes exactly that, silently, for anybody still
holding the link. The one cancel the feature had could be reversed by the
person it was aimed at.
So: a new STATUS_REVOKED, outside the pending() scope that both the
redemption and the resend doors look through. A revoked link is dead to all
three things a live one can do -- opening the form, redeeming it, and
asking for a replacement -- and nothing but sending a fresh invitation
brings it back.
The list sits under the invite form rather than on a screen of its own,
because the person who wants to cancel an invitation is the person who just
sent one. It shows outstanding invitations only: pending, expired ones
included. An expired invitation is not inert until it is revoked, so hiding
it would hide the rows most worth a decision -- which is why they sort to
the top, soonest expiry first.
Revoking is gated by create_clients, the same authority as sending:
whoever may invite somebody may take it back. It is logged, like sending
and redeeming already were. The row is kept rather than deleted, for the
reason a superseded one is kept -- the activity log names who invited this
address and when, and that trail should still lead somewhere.
Verified in a browser, not only in tests: the screen mounts, both rows
render, and the expired one carries its badge.

Staff can now invite a specific address to register instead of typing a
password for somebody and finding a way to get it to them. The invited
person sets their own, the link is locked to the address it was sent to,
and an invitation always activates the account regardless of the
auto-approve setting -- naming an address is already the decision the
approval queue exists to make for one nobody named.
Two fixes ride along: outgoing mail now reads the installation's own site
name in its title, header and signature rather than the one baked into
config('app.name') at install time, and the CSRF cookie name is read per
request rather than captured once at load.
Follow-up work, tracked separately: an invitation cannot be cancelled --
there is no pending-invitations screen and no revoke, so letting one expire
is the only way to take it back, which the self-service resend button then
undoes. Redemption also needs the address-availability check every other
non-form caller of ClientProvisioning makes.
Thanks @mash2k3.

v1 could preview four kinds of file in a modal — images, video, audio and
PDF. v2 previewed only images, and not by decision: preview shipped as part
of the image *thumbnail* work (1c68aa1), so "previewable" quietly became a
synonym for "GD can decode it". FileThumbnailController::preview() gated on
ThumbnailGenerator::SUPPORTED_MIME_TYPES, the frontend mirrored the same
four types, and the dialog was a hardcoded <img>.
Rather than widen that list — it drives pathFor(), extensionFor(),
generate() and FileDiskCleanup, and a video reaching getimagesize() is a
500 — this separates the two questions. PreviewKind now answers "may these
bytes be served inline, and what element renders them?", while
ThumbnailGenerator keeps answering the narrower "can this app decode it
itself?", which is what renditions, the cache and the watermark hook
actually depend on. Image delegates to it so the two cannot drift.
The allowlist stays a security boundary: mime_type is sniffed from the
bytes, so text/html and image/svg+xml remain excluded, and PreviewKind is
deliberately narrower than "formats a browser might cope with" — no
quicktime, avi or matroska, because an embedded player for those shows a
black rectangle. Those still download exactly as before.
docs/security-audit-2026-08-05.md finding 1 recorded that adding
application/pdf "should be a conscious decision". This is that decision,
and three things were measured rather than assumed:
- An <iframe sandbox> cannot be used. Chrome refuses to run its PDF viewer
in a sandboxed frame at all (ERR_BLOCKED_BY_CLIENT, with or without
allow-same-origin) — the attribute removes the feature, it does not
harden it.
- nginx's `Content-Security-Policy: sandbox; default-src 'none'` on
/protected-files/ does work (a <video> frame lands in an opaque origin),
but Chrome exempts its PDF viewer from it, so it is not what protects
the PDF case.
- What does is the allowlist plus the browser's own PDF sandbox, where PDF
JavaScript has no DOM and no cookies.
Range requests were verified end to end: 206 with a correct Content-Range,
a byte-perfect file reassembled from three ranges, and a real browser
seeking to 10s of a 20s clip. nginx drops the upstream Content-Length on
the X-Accel path, so there is no collision.
Two settings, both defaulting on so no installation loses what it has:
clients_can_preview_files and public_listing_preview_enabled. Staff are
never gated. The anonymous side needed a route of its own — there was no
public preview endpoint — with its own throttle bucket, since a bare
throttle: shares one counter across that whole block.
A preview now logs at most one FilePreviewed per viewer per file per five
minutes: a <video> turns one deliberate act into a long tail of Range
requests, and a row each would bury the log.
Also fixes a layout bug the tests could never catch. A portal file row was
flex justify-between with three children — name, comment trigger, download
— so the middle one settled wherever the name happened to end and the
comment icon sat at a different place on every row. The name block now
takes the slack and every action lives in one trailing group, with the
comment trigger in a fixed-width slot so the icons form a column. And
because half the previewable files have no thumbnail to click — a PDF, an
mp3 and an mp4 all render as a generic icon — every row gains an explicit
PreviewAction beside DownloadAction, matching whatever style that theme
gives its download control.
The activity log is where an administrator goes to answer "what changed
on this installation, and when" — and the largest change of all was not
in it. A new version arrived, the schema moved, behaviour changed, and
the log said nothing.
`projectsend:update` now records it as a system action, naming both
versions: "Updated ProjectSend to 2.1.0, from 2.0.1". It appears in the
log's own action filter without further work, since that list is built
from the enum.
Only a real version change is written. The container entrypoint runs this
command on every boot, so logging unconditionally would bury the log
under an entry per restart, and a first boot is an installation rather
than an update — SetupCompleted already covers that. "First boot" is
decided by whether any migration had run before this one, not by whether
a version was recorded: the first update of any installation older than
this command finds no recorded version, and that update is exactly the
one worth logging. It says "from an unrecorded version", once, ever.
Writing the entry cannot fail the update: an update that worked must not
report failure because its own paperwork did.
Verified on a real manual install — the row renders as
"Updated ProjectSend to 2.0.3, from 2.0.2", attributed to the system.
