Detected by Aeon + Semgrep (5x use-defused-xml ERROR).
Severity: medium
CWE-776 (billion laughs) / CWE-611 (XML external entity)
Five XML parse sites pass response bodies into the Python stdlib
xml.etree.ElementTree without protection against entity expansion
attacks. Python's ElementTree still permits internal entity references
by default (per the docs vulnerabilities table), so a malicious or
compromised upstream can ship a "billion laughs"-style payload that
expands to gigabytes in memory.
The user-controllable site is sb_monitor._parse_rss: the OpenClaw skill
exposes add_custom_feed(name, url, ...) to the agent, then
poll_custom_feeds fetches feed.url and passes the body to
xml.etree.ElementTree.fromstring with no host allowlist or
entity-bomb defence. The other four sites (psk_reporter_fetcher,
aircraft_database, cctv_pipeline x2) parse XML from hard-coded
upstreams (pskreporter.info, s3.opensky-network.org,
datos.madrid.es); defence-in-depth for upstream-compromise/MITM.
Switch all five call sites to defusedxml.ElementTree. Same
fromstring/find/findall/iter/findtext API, but rejects entity
references by default (raises defusedxml.EntitiesForbidden).
Confirmed locally that a 4-deep billion-laughs payload that
expands to 3000 chars under stdlib ET is rejected by defusedxml.
Added defusedxml>=0.7.1 to backend/pyproject.toml dependencies.

Ship the v0.9.79 runtime refresh with transport lane isolation, Infonet secure-message address management, MeshChat MQTT controls, selected asset trail behavior, telemetry panel refinements, onboarding updates, and desktop/package metadata alignment.
Also ignore local graphify work products so analysis folders do not leak into future commits.
Add Tor/onion runtime wiring and faster Infonet node status refresh.
Keep node bootstrap state clearer across Docker and local runtimes.
Use selected aircraft trail history for cumulative tracked-aircraft emissions.
Full import audit found these packages used but missing from
pyproject.toml — all silently broken in Docker:
- meshtastic: MQTT protobuf decode (why US/LongFast chat was empty)
- PyNaCl: DM sealed-box encryption
- vaderSentiment: oracle sentiment analysis (unguarded, would crash)
paho-mqtt v2 changed Client constructor and on_connect callback
signatures, breaking the Meshtastic MQTT bridge. Pin to <2.0.0
so the existing v1 code works correctly in Docker.
paho-mqtt was missing from pyproject.toml, causing the Meshtastic MQTT
bridge to silently disable itself in Docker — no live chat messages
could be received. Also improve Infonet node status labels: show
RETRYING when sync fails instead of misleading SYNCING, and WAITING
when node is enabled but no sync has run yet.
Docker image was crash-looping with `ModuleNotFoundError: No module named 'orjson'`
because these packages were imported but not declared as dependencies.

CI runs `uv sync --group dev` but only a `test` group existed.
Renamed to `dev` and added ruff + black so Docker Publish can pass.
