The root password hash for a shut-off VM used crypt_r where installed
(Python 3.13) and fell back to the stdlib crypt, which Python 3.11 and
3.12 deprecate: `python -W error::DeprecationWarning manage.py check`
failed there. crypt-r (the same module, it requires Python 3.11) is now
installed from 3.11, and the module is chosen by the Python version;
3.10's crypt is not deprecated.
The updates on the login, SSH and serial console paths:
- django-otp 1.7.5 revokes the session of a device that is no longer
confirmed.
- python-engineio 4.15.1 and python-socketio 5.18.1 refuse requests and
events before the connection completes, HTTP requests after the
upgrade to WebSocket, and ../ in static file paths.
- paramiko 5.1.0 fixes agent keys and the default RSA signature
algorithm.
django-rest-knox 5.1.1 changes only its project's references, and
django-auth-ldap 5.4.0 drops Python 3.10, which the panel supports;
both stay.
django-bootstrap-icons (last release July 2024) only read the SVG of
each {% bs_icon %} from static/icon_cache; for an icon not there it
fetched the SVG from a CDN while rendering the page, and it brought
defusedxml along. A 20-line template tag in webvirtcloud reads the
same files; the package, its CDN path and the BS_ICONS_CACHE setting
go. requests stays: websockify needs it.
Cloud images read their first-boot settings with cloud-init. The panel
served them only over HTTP, which a VM reaches only with the network
and a reverse DNS name for its address. A new VM can now carry them
itself: Cloud-init seed (Advanced) on the create form, or cloud_init in
the API.
The job writes a NoCloud seed, an ISO labelled cidata, into the disk's
directory pool as cidata-<uuid>.iso and puts it in the VM's CD-ROM
drive. Its meta-data holds the VM's UUID as instance-id and its name as
hostname, written as JSON so a VM named 123 or yes keeps a string
hostname; its user-data is what the HTTP datasource serves, with the
creating user's SSH keys. The ISO is built with pycdlib and written
through a libvirt stream, as the NVRAM copy is, now one helper for both.
A seed needs a CD-ROM bus and a directory pool, else the create is
refused. A failed create deletes the seed with the new disk, recovery
names one left behind, and deleting the VM with its disks deletes its
seed, found in the pools by name even when ejected. A clone's drive is
left empty: the seed is the source VM's identity.
The REST API took only the login session, so a script could not use it
without a browser. A user now makes API tokens on the profile page (API
Tokens tab): a name, and an expiry of 30, 90 or 365 days or none. The
token is shown once, on a page that is not cached, and then kept only as
a SHA-512 digest; the list shows its name, first characters, creation
and expiry, and a token is deleted there. Tools send it as
"Authorization: Token wvc_...", and act as its user, with that user's
permissions. Making and deleting a token is logged, without the token.
A password alone (HTTP Basic) still does not reach the API, as it would
skip the OTP second factor: a token is made in a session that passed the
login and its OTP. The token class comes first, so a refused request gets
401 with its challenge instead of 403.
django-rest-knox 5.1.0 provides the tokens (accounts.ApiToken adds the
name); settings.py takes "knox", KNOX_TOKEN_MODEL and REST_KNOX from the
template.
The Administration menu gets "VM report (.xlsx)", a workbook for
superusers. The VMs sheet has one row per VM on every compute, shut-off
ones and those the panel has not registered too: name,
state, host, OS and OS family, vCPUs, memory, IP addresses and where they
came from, MAC addresses, owners, and whether the panel has registered
it. A Coverage sheet says when it was made and what could not be read.
The addresses come from the same live reading as the address search,
now shared by both. The OS is the guest agent's (libvirt's guest info)
or, without one, the libosinfo id a tool such as virt-install wrote into
the definition. Link-local IPv6 addresses are left out of the report.
Text cells stay text: a VM name starting with "=" is not a formula.
openpyxl 3.1.5 writes the workbook.
django-auth-ldap, python-ldap and pyasn1 move to
conf/requirements-ldap.txt. Installs without LDAP no longer need the
openldap and sasl headers that pip builds python-ldap with; the
installer and the README's system packages drop them, and the README's
LDAP section installs them with that file. The settings already work
without the module.
The Docker image and dev/requirements.txt keep LDAP, so CI still builds
and audits python-ldap.
A theme change compiled Bootswatch with libsass (34 MB, upstream
deprecated) into two tracked files, which updates, rollbacks and new
Docker containers then reset. The 27 themes now ship as
static/css/themes/<theme>.min.css, built by "manage.py build_themes";
the Settings page only saves the theme name and every page links that
file (zephyr when no settings are in context, as on the 500 page).
libsass moves to dev/requirements.txt; a test checks that each shipped
file is its theme compiled from dev/scss. The "Theme SASS Path" setting
is removed, and the theme default "flaty", a typo that never applied,
becomes zephyr, the theme those installs showed. The update and
rollback steps restore an older version's rewritten theme files only
where they are modified.
eventlet is in maintenance mode. socketiod now runs python-socketio in
threading mode under gunicorn (one gthread worker, which holds the
sessions), with simple-websocket, already a python-engineio dependency.
gunicorn waits 1 s on stop: an open console never finishes, and its
worker ends when the pty closes. The forward loop waits in select
instead of polling, and a stopped worker is reaped by a blocking
waitpid. eventlet leaves the requirements.
django-qr-code was used for one thing: the QR code in the OTP e-mail,
as an inline SVG and a PNG. It brought pydantic, pydantic-core,
annotated-types and typing-inspection (about 10 MB) and, from 5.0 on,
Pillow. segno, which it used underneath, now draws both images with the
same options (error correction M, 4-module border, 1.8 mm SVG modules,
12 px PNG modules); the SVG, the PNG and the alt text are byte for byte
what django-qr-code 4.2 produced. account.html loaded the tag library
without using it.
django-bootstrap-icons (template tags; it downloads an icon missing from
static/icon_cache) and websockify depend on requests, unpinned. On a
host that already has python3-requests, the installer's venv kept the
distro's idna, requests and urllib3 (Rocky 10: idna 3.7, urllib3
1.26.19; Ubuntu 24.04: idna 3.6, requests 2.31.0, urllib3 2.0.7), all
with advisories, and the panel loads them with its templates. Checked
in fresh Rocky 10 and Ubuntu 24.04 containers with python3-requests
installed first: all three come from the venv.
The installer's venv sees the system site packages, and pip keeps a
system package that meets a requirement. On openSUSE Leap 15.6 the LDAP
login thus ran on the distro's python-ldap 3.4.4 (CVE-2025-61911, a
filter-escaping bypass, and CVE-2025-61912) and pyasn1 0.5.0
(CVE-2026-30922 and others), which django-auth-ldap loads through
ldap.controls. python-ldap>=3.4.5 and pyasn1>=0.6.4 make pip install
fixed copies in the venv. python-ldap builds there, so openldap2-devel
joins the openSUSE package lists (installer, manual and development
setup) and the update steps. Checked in a fresh Leap 15.6 container
with the installer's package list: 3.4.8 and 0.6.4 from the venv,
ldap.controls imports.
1.7.4 no longer preselects a device in the otp_device field. The login
form chooses the user's confirmed TOTP device itself and ignores that
field, so the login is unchanged (OTP login tests pass).
3.18.2 hardens content negotiation against large Accept headers
(GHSA-33wh-fxxf-88vv) and refuses non-text charsets
(GHSA-3547-9m27-7rxg); the API reads both. 3.18 drops Django < 5.2 and
reports list serializer errors as a dict; the API's many=True
serializers only render output.
Security release of 2026-10-06. Two of its fixes reach this app: a
quadratic HTTP header parsing DoS reachable without a login
(CVE-2026-84429) and long language codes through LocaleMiddleware
(CVE-2026-77050). The GeoDjango and model formset fixes do not apply.
Nothing limited failed logins: a password could be guessed at the speed
the server answers. django-axes (8.3.1, Django 5.2, Python 3.10-3.13)
now counts them.
- A user is locked for the address the failed logins come from
(username and IP together), so an attacker cannot lock someone out
from elsewhere and users behind one NAT address do not share a lock.
A successful login resets the count. axes sits in front of every
authentication: the login page with or without OTP, LDAP and the API.
- The number of failed logins (default 5) and the lock time in minutes
(default 15) are on the Settings page (LOGIN_FAILURE_LIMIT,
LOGIN_LOCKOUT_MINUTES, added by migration appsettings.0014) and apply
at once; an invalid value falls back to the default. Unlock with
"manage.py axes_reset_username <username>".
- Behind the bundled nginx every request comes from 127.0.0.1; the
client address is read from X-Real-IP, which nginx sets, but only for
requests from a loopback address or from LOGIN_TRUSTED_PROXIES, so a
forged header does not escape a lock.
settings.py.template gets the app, middleware, backend and AXES_*
settings; README tells existing installations what to copy. Tests that
call client.login now pass a request, which the axes backend needs.
The new tests fail with axes disabled.
ldap3, markdown, zipp, qrcode and tzdata are not imported anywhere and
no installed package needs them on Linux with Python 3.10-3.13: LDAP
login uses python-ldap through django-auth-ldap, QR codes come from
django-qr-code (segno), qrcode is only an optional django-otp extra,
tzdata is a Windows-only Django dependency and TIME_ZONE is UTC.
python-engineio stays pinned next to python-socketio, which requires it.
The test suite passes with the five packages uninstalled.
django-login-required-middleware is dropped; Django 5.1+ ships the same
middleware. The login page is already marked login_not_required by
Django; email_otp gets the decorator, which replaces
LOGIN_REQUIRED_IGNORE_VIEW_NAMES. The datasource still requires login.
Existing settings.py files still name the old middleware. A system
check (accounts.E002) stops migrate and the server until MIDDLEWARE
uses Django's middleware, instead of an ImportError at startup; the
README has the steps.
A new matrix test walks every URL anonymously: everything outside a
short allowlist (login pages, the OpenAPI docs) sends the visitor to
the login page, and API views deny with 401/403. It passed with the old
middleware first and passes unchanged now.
Django 4.2 reached end of life on 2026-04-07.
- Django==5.2.17; django-login-required-middleware 0.9.0 keeps working
(the authorization matrix passes).
- USE_L10N removed from the settings template.
- Log out is a POST form in the navbar; Django 5 removed GET logout.
- pip-audit in CI no longer ignores the Django 4.2.30 advisories.
- README: Django 5.2, backup step and upgrade notes for existing
settings and GET logout callers.
python -Wd manage.py test shows no Django deprecation warnings. The live
libvirt suite passes on 5.2 and on 4.2 against a RHEL qemu-kvm host.
- Matrix 3.10-3.13; pip cache keyed on the requirements.
- New steps: makemigrations --check, spectacular --validate
--fail-on-warn, check --deploy --fail-level ERROR, pip-audit of the
installed environment (the Django 4.2.30 advisories are ignored until
the Django 5.2 upgrade), and a Docker image build.
- The separate vrtManager unittest run is dropped; manage.py test
already runs those tests.
- CodeQL also runs on pull requests to master.
- Docker installs into a plain venv instead of using the distro's
python3-lxml and python3-libvirt; lxml>=6.1, since the distro's
lxml 5.2.1 has CVE-2026-41066.
- dev requirements add ruff and pip-audit.
