# Calibre-Web
Calibre-Web is a web application that browses, reads, and downloads eBooks from an existing Calibre library database. It serves as the web frontend for the Calibre e-book manager.
**Host:** Dankserver — **Hostname:** `books.dankserver.local` — **Docs:** https://github.com/linuxserver/docker-calibre-web
## Facts
| Item | Value |
|------|-------|
| Latest version | 0.6.27-ls397 |
| Image | `lscr.io/linuxserver/calibre-web:0.6.27-ls397` |
| Base OS | Ubuntu Noble (24.04 LTS, since 2024-12-05) |
| Port | 8083 (host) → 8083 (container) |
| Default login | `admin` / `admin123` |
| Docker mod | `linuxserver/mods:universal-calibre` (ebook conversion, x86-64 only) |
| Volumes | `/config` (internal database + config), `/books` (existing Calibre library) |
| Extra tools | `unrar` at `/usr/bin/unrar`, `kepubify` at `/usr/bin/kepubify` (pre-configured since 2025-01-07) |
## CVEs Fixed in Latest Version
| CVE | Issue |
|-----|-------|
| CVE-2025-7404 | External binary names (e.g. `unrar`) restricted to prevent RCE |
| — | XSS in book comments imported via Calibre, now sanitized |
Additional packages added: `libxfixes3` and `libasound2t64` to support epub-to-pdf conversion. The `--no-sandbox` flag is applied to qtwebengine to prevent crashes in Docker.
## Configuration
### Environment Variables
| Variable | Value | Description |
|----------|-------|-------------|
| `PUID` | `1000` | User ID |
| `PGID` | `1000` | Group ID |
| `TZ` | `Etc/UTC` | Timezone |
| `DOCKER_MODS` | `linuxserver/mods:universal-calibre` | Optional: enables ebook conversion tools |
| `OAUTHLIB_RELAX_TOKEN_SCOPE` | `1` | Required for Google OAuth |
### Setup Steps
1. Point the container at the Calibre library directory (set the `/books` volume).
2. Log in with `admin` / `admin123` and change the password immediately.
3. In Basic Configuration → Calibre Database → set Location of Calibre database to `/books`.
4. In Basic Configuration → External Binaries → set the directory to `/usr/bin/` for Calibre-Web >= 0.6.22.
5. **kepubify is pre-configured** since version 0.6.27. No need to set the kepubify path manually.
6. Set up Google OAuth if desired (requires `OAUTHLIB_RELAX_TOKEN_SCOPE=1`).
## Volumes
| Container path | Host path (convention) |
|----------------|------------------------|
| `/config` | `/opt/calibre-web/config` |
| `/books` | The existing Calibre library directory (user-entered during setup) |
## Docker Compose
```yaml
services:
calibre-web:
image: lscr.io/linuxserver/calibre-web:0.6.27-ls397
container_name: calibre-web
restart: unless-stopped
environment:
PUID: "1000"
PGID: "1000"
TZ: Etc/UTC
OAUTHLIB_RELAX_TOKEN_SCOPE: "1"
ports:
- "8083:8083"
volumes:
- /opt/calibre-web/config:/config
- /opt/calibre-web/books:/books
healthcheck:
test: ["CMD", "curl", "-f", "http://localhost:8083/"]
interval: 30s
timeout: 10s
retries: 3
```
## Gotchas
- **Wrong database path:** Login appears to succeed but the library is empty. Verify the Calibre database path in the admin page.
- **Ebook conversion:** Requires the `universal-calibre` Docker mod AND the external binary path set to `/usr/bin/` (directory, not full path to `ebook-convert`).
- **Google OAuth:** Set `OAUTHLIB_RELAX_TOKEN_SCOPE=1` or OAuth login fails.
- **calibre 9.9.0 content server security fix:** A bug since v6.16.0 allows any user with server access to read non-Calibre files on the host. Upgrade to 9.9.0+ if serving content to untrusted users.
