Reported by @choewonwoo1817 as GHSA-wgxf-v8cr-37mj, with a working
end-to-end reproducer against Keycloak.
`where('email', $address)` is not an exact match. It is whatever the
database says equality means, and the collation INSTALL.md tells people to
create — utf8mb4_unicode_ci — folds accents:
administrator@example.com = administrator@éxample.com -> 1
Those are two different domains. The second is xn--xample-9ua.com, which
somebody else can register and honestly verify at an OIDC provider. So an
attacker with no account here could sign in as themselves and be handed
the first account: SocialAuthenticator found it, linked their subject to
it permanently, and started a session. No password, no interaction from
the owner, an administrator session where that account was one.
Comparison now happens in PHP, in one place, on every driver. Case is
still folded because that is a real requirement — addresses are stored
lowercased and a provider may send any case — and mb_strtolower folds case
without folding accents, which is exactly the line to draw.
Three call sites move to it and two deliberately do not. Loose matching is
right when *refusing* and wrong when *selecting*: AvailableEmailRule and
ClientProvisioning ask "is this address free", where a collation that says
no to a near-miss refuses more registrations, which is the safe direction.
The three that ask "which account is this" are the social path, the login
form (where a password still gated it, so it was confusion rather than
takeover) and the erasure command (irreversible, and the wrong row is the
wrong person).
The test story is the part worth reading. The suite runs on SQLite, whose
`=` is byte-exact, so this defect does not exist there and never did —
which is how it survived six releases with everything green. A test
written the obvious way passes on unfixed code. So the comparison is
pinned by driver-independent tests that always run, and the chain is
proved by AccountLookupCollationTest, which skips unless the connection is
MySQL and carries the command to run it. Run against real MySQL with the
real collation: it fails on the old code and passes on the new.
ProjectSend
Share files with your clients, from your own server.
ProjectSend is a self-hosted application for getting files to the people you work with. You upload what you want to send, choose exactly who can see it, and each client signs in to their own private page to download it.
No public link passed around by email, no third-party service holding your clients' documents, no per-seat pricing. It runs on your server, and the files stay there.
Prefer not to run the server yourself? ProjectSend Cloud is the official hosted version of ProjectSend, run by the same team — every subscription funds this free software. The line between the free core and Cloud, and the commitments that go with it, are set out in LICENSING.md.
What it does
For the people you send to
- A private area per client, showing only what has been shared with them
- Sign in with an email address, with optional two-factor authentication
- Search, filter and sort their files; download one, several as a zip, or a whole folder
- Optional comments on a file, so questions live next to the thing they are about
- Email notifications when something new arrives, in their own language
For you
- Resumable uploads that survive a dropped connection, so large files actually arrive
- Organise with folders, categories and client groups
- Share with one client, a whole group, or publicly — and set an expiry date or a download limit
- Thumbnails and previews for images and documents
- Storage quotas per client, and custom fields for the details you need to keep on them
- A full activity log and download history: who got what, and when
For the installation
- Roles and permissions for your own team, so an uploader is not an administrator
- Sign-in the way you already work: LDAP, social sign-in, or plain email and password
- Themes for the client-facing pages and for outgoing email
- 16 languages
- A REST API with scoped tokens and generated OpenAPI docs
- Privacy controls, including GDPR-grade account erasure with a grace period
- Local disk, S3-compatible storage, or Google Cloud Storage
Screenshots
The dashboard — what is in the installation, and what has been happening in it.
Your library — folders, categories, and who each file is shared with.
What your client sees — only their files, nothing else.
Getting started
With Docker — the quickest path, and the one we recommend. Nothing to build: the published image ships with its dependencies and its frontend already compiled.
curl -O https://raw.githubusercontent.com/projectsend/projectsend/main/docker/production/compose.example.yaml
# edit the passwords and APP_URL in it, then:
docker compose -f compose.example.yaml up -d
Open APP_URL and the first thing you see is a setup screen that creates your administrator
account — or uncomment ADMIN_EMAIL and ADMIN_PASSWORD in the file first, with a password of
your own, and it is created for you.
Before you put real files in it, read DOCKER.md — where your database and uploads actually live, how to move them onto paths you chose, and how to back them up so an upgrade can't take them with it.
Without Docker — for servers where it isn't an option, install from a release zip.
INSTALL.md covers requirements, .env, nginx, the background worker and cron,
updating and troubleshooting. You do not need Composer or npm on the server; the zip ships ready to
run.
Already running it? UPDATE.md is how you move to a new version — one command on Docker, one script on your own server, and what to check afterwards either way.
Want to work on ProjectSend itself? Cloning the repository gets you a development copy, not an installation: the dependencies and the compiled frontend are deliberately not in git, so a clone needs Composer and npm before it runs. CONTRIBUTING.md has the sequence, and it is short.
Coming from ProjectSend Legacy?
The previous generation of ProjectSend lives on at projectsend/legacy. This is a rebuild rather than an upgrade, so moving across is an import rather than an update — install fresh, then bring your old site into it with the migration tool: accounts, clients, groups, categories, folders, files and history.
It never writes to your old install, and any run can be undone with a single command. MIGRATING-FROM-V1.md explains what comes across, the two routes (same machine, or a portable export from a server you can't reach), and the one change your clients will notice: they sign in with their email address now, using the same password.
