Matrix outbound image downloads validated only the final URL after
following redirects, so a public URL that 302-redirects to loopback /
private-network / cloud-metadata endpoints had already connected to the
unsafe hop before the check ran.
Re-validate every redirect hop before following it:
- aiohttp path resolves redirects manually with allow_redirects=False,
validating each Location via is_safe_url (aiohttp can't use the httpx
response event hook).
- httpx fallback installs the shared _ssrf_redirect_guard event hook.
Regression tests cover per-hop blocking of an unsafe redirect, following
a safe redirect chain, and httpx guard wiring.
An invite to a room with no remaining members surfaces as "no servers
in the room have been provided" or "room not found" on join. The pending
invite was never cleared, so every gateway startup re-attempted the join
and re-emitted the warning indefinitely.
Detect that specific failure mode by narrow error-message match and call
leave_room to decline the invite; transient/network errors leave the
invite untouched for the next sync. Adds 5 tests.
Reimplements the matrix portion of #33953 onto the current plugin adapter
(gateway/platforms/matrix.py was relocated to
plugins/platforms/matrix/adapter.py since the PR was opened). The two
gateway/status.py fixes from that PR (wrapper-subcommand rejection,
psutil start-time fallback) already landed on main independently.
Reported by @Bougey; original patch authored by @KiraKatana.
The Matrix adapter's _upload_file fell back to sending
"(file not found: {file_path})" directly into the room — the same
host-path leak class fixed for the base adapter and Slack in the
previous commit. Replace it with a friendly notice, log the path at
WARN for operators, and preserve any caller-supplied caption.
Two platform-security hardenings:
- Matrix: _on_invite now checks the inviter against the existing
allow-list (_allowed_user_ids / GATEWAY_ALLOW_ALL_USERS) before
auto-joining. Without this any federated Matrix user could invite
the bot into arbitrary rooms, exposing its presence and metadata.
The message and reaction paths already enforce this allow-list; the
invite path bypassed it.
- Mattermost: _api_get / _api_post / _api_put reject any path
containing '..'. WebSocket-event values (channel_id, post_id,
file_id) are interpolated directly into API paths, so a malicious or
compromised server could craft traversal payloads to make the bot
issue authenticated requests to arbitrary endpoints with its bearer
token.
The configurable-E2EE-passphrase change from the original PR is dropped:
the matrix adapter was rewritten onto mautrix and the passphrase-protected
key-export file no longer exists.
Rebase onto plugins/platforms/matrix/adapter.py (code moved from
gateway/platforms/matrix.py). Same logic: _on_invite checks is_direct
on invite events and calls _record_dm_room to persist in m.direct
account data.
Fixes#44679
After a prolonged outage the in-process network-error ladder escalates to
fatal and GatewayRunner._platform_reconnect_watcher rebuilds a fresh adapter
that reconnects through the bootstrap path. That path called
start_polling(drop_pending_updates=True), discarding every update Telegram
queued during the outage — all messages sent while the bot was down were
silently lost. The in-process ladder and 409-conflict handler already passed
drop_pending_updates=False; only bootstrap did not distinguish a cold first
boot from a reconnect.
Thread an is_reconnect signal from the watcher through
_connect_adapter_with_timeout into adapter.connect(). The base
BasePlatformAdapter.connect() gains a keyword-only is_reconnect=False so every
adapter inherits a tolerant signature (no per-platform breakage when the
runner forwards the kwarg). Telegram translates is_reconnect into
drop_pending_updates=not is_reconnect on both the polling and webhook bootstrap
calls. Cold boot still drops the stale queue; a watcher reconnect preserves it.
Fixes#46621.

Most Matrix clients auto-set a room name when creating a DM (e.g.
"Alice & Bot" from participant display names), so the old
`is_direct and not has_explicit_name` heuristic classified virtually
all client-created DM rooms as "room", forcing require_mention gating
in legitimate one-on-one DMs.
member_count is now the primary DM signal: <=2 members means the room
is necessarily a 1:1 conversation, regardless of m.direct or an explicit
name. A room that grew to 3+ members but is still in stale m.direct is
still classified as a room (conflict flag set). Falls back to the
m.direct + name heuristic when the count is unavailable.
Also hardens _get_room_member_count with a joined_members API fallback
when the cache-backed state_store is empty.
Salvaged from #48554 by @justemu onto the current plugin adapter path
(gateway/platforms/matrix.py -> plugins/platforms/matrix/adapter.py).
Fixes#48551
Follow-up to ScotterMonk's cron-truncation fix:
- Remove HERMES_DELIVERY_MAX_PLATFORM_OUTPUT env var. Behavioral config
belongs in config.yaml, not a new HERMES_* env var (.env is secrets
only). The actual bug is fixed entirely by the adapter-aware skip; the
configurable cap was unneeded scope. MAX_PLATFORM_OUTPUT is a constant
again, collapsing the max_output=0 disable branch and the
audit-vs-truncation threshold divergence.
- Flag the remaining verified-chunking adapters (slack, matrix, feishu,
mattermost, teams, whatsapp, whatsapp_cloud, weixin, bluebubbles,
yuanbao) with splits_long_messages=True so the fix covers the whole
bug class, not just Discord/Telegram. Each verified to chunk in its
own send() via truncate_message().
- SMS deliberately left False: it chunks for normal replies but a
multi-segment cron blast is cost-bearing; the 4000-cap + file save is
the safer default there.
- Update tests: drop the two env-override tests, add a test asserting a
save failure during truncation (non-chunking) propagates.
Salvage of PR #41284 onto current main. Relocates the last 9 inline messaging
adapters (+ satellites: telegram_network, feishu_comment/_rules/meeting_invite,
wecom_crypto, wecom_callback) from gateway/platforms/ into self-contained
bundled plugins under plugins/platforms/<x>/, discovered via the platform
registry. Strips the per-platform core touchpoints from gateway/run.py,
gateway/config.py, hermes_cli/gateway.py, hermes_cli/setup.py, and
tools/send_message_tool.py.
Carries forward the migration fixes (explicit enabled:false honored,
get_connected_platforms forces discovery, plugin is_connected via
gateway.get_env_value, logs --component gateway matches plugins.platforms.*,
matrix hidden on Windows).
Additionally ports config keys main added since the PR base: the matrix
plugin's _apply_yaml_config now also covers allowed_users,
ignore_user_patterns, process_notices, and session_scope (the inline
gateway/config.py matrix block gained these in the 1340 commits the PR sat
open; they would otherwise have been silently dropped on deletion).
