omarchy-notification-send now calls org.freedesktop.Notifications.Notify
directly with `busctl --user`, instead of shelling out to notify-send. Each
value is one typed D-Bus parameter, so there is no argv/option layer that could
reinterpret a relayed headline like `--hint=…` or `-rf` as an option or a hint:
the summary and body are strings, and omarchy-exec-argv is built only from
--exec. A leading `--` keeps busctl's own getopt from reading a dash-leading
value as a busctl option.
Map -i to app_icon, -t to expire_timeout, and urgency to the byte hint; unknown
options are now a hard error rather than a silent pass-through. Route the unused
hypr o.notify helper and the sample hooks through the wrapper too, and tighten
the bin-style test so nothing under bin/ may call notify-send. The test stubs
busctl and trips if notify-send is invoked.
The argv click command closed injection through the hint's value, but the
sender still handed the headline and description to notify-send bare. A
value beginning with a dash is parsed there as flags, and one shaped like
`--hint=string:omarchy-exec-argv:[...]` is read as a hint of its own --
libnotify keys hints in a hash table, so the later of two replaces the
earlier and a forged headline outranks the vector --exec built.
That is reachable without any --exec in sight: omarchy-tailscale-send
passes a single file's basename verbatim as the description, so a file
named like the hint gives its click action to whoever chose the name.
Put the headline and description behind a `--` so notify-send reads them
as text, and refuse any pass-through word carrying omarchy-exec-argv --
--exec is the only thing that may build a click command.

Replace --exec-arg with an ergonomic --exec that consumes the rest of the line
as the click command. The caller's shell tokenizes the words into discrete
arguments before the tool sees them, and the shell runs them as positional
parameters (never a re-parsed string), so safety is identical to the argv form
while the call sites read naturally: `--exec omarchy toggle something`.
Crucially the tool never splits a string itself — a single quoted whole-command
argument is rejected and points at the unquoted form, because whitespace-
splitting a string hands argument boundaries to whoever controls its content
(the injection we are avoiding). --exec must come last; migrate every caller.
A free-form shell-string --exec sitting next to the safe --exec-arg is a
standing invitation for the next caller to interpolate untrusted data and
reintroduce the RCE. Remove it: omarchy-notification-send --exec now errors and
points at --exec-arg, and the shell drops the omarchy-exec string hint and its
bash -lc execution path, leaving only the argv path.
Migrate the remaining string callers (the first-run invitation hooks, wifi and
welcome prompts) to --exec-arg, and update their notification mocks. Trim the
verbose security comments added along the way.
Quickshell.execDetached(argv) ran the click target with only the shell
process's stripped environment, so GUI actions like the screenshot editor
(tensaku-edit) — resolved on the login-shell PATH the old `bash -lc` string
exec provided — stopped launching on click.
Run the argv through `bash -lc 'exec "$@"'` instead: the script text is a
constant and the arguments are passed as positional parameters, which bash
expands without re-tokenizing or re-evaluating, so injection safety is intact
while PATH and session env match the old behavior exactly.
The click action of a notification was a free-form shell string run through
`bash -lc`, safe only when every sender shell-quoted every interpolated value
perfectly. One slip is RCE: a hostile yt-dlp video title forged an output
record and injected an mpv option into the click command (mehmetince.net RCE,
partially addressed by #7847).
Add a parameterized transport: omarchy-notification-send gains --exec-arg
(repeatable), encoding a JSON argv into the omarchy-exec-argv hint. The shell
runs it with Quickshell.execDetached(argv) and no shell, so data an attacker
controls is only ever one argument and can never be reparsed as a command. The
shell fails closed on a malformed argv hint.
The legacy free-form --exec string is retained but honored only from Omarchy's
own omarchy-action toasts, and deprecated. Migrate all in-repo callers
(screenshot, screen recording, taildrop receive, migrate-notify, crash-watch,
yt-dlp host) to --exec-arg. Update docs and tests.
Every reference doc was audited claim-by-claim against the code.
file-layout and omarchy-shell were the most decayed (renamed commands,
the etc/ overrides source split, dead IPC entry points and example keys);
update-process lagged the recent pipeline changes and gains a channels
section; theming and audio-tuning were accurate but thin around their
lifecycles.
New reference docs for the subsystems that had none: the menu system,
the CLI router, the notification daemon, and the non-acceptance test
architecture. AGENTS.md links the two of those agents will need most.
