GET /api/v1/ddns and /api/v1/notification returned full objects with
plaintext credentials (Cloudflare/TencentCloud secrets, webhook URLs
with embedded bot tokens, Authorization headers). Redact these fields
in the list responses.
Since the frontend edit form repopulates from the list endpoint, the
update handlers now treat an empty submitted credential as "no change"
and preserve the stored value, preventing accidental secret wipes.

RetentionWindow() trimmed offline-rule samples to 1, but Check's offline
branch reads points[len-Duration:] and needs Duration samples. The window
never filled, boundCheck always returned "passed", and offline alerts never
fired a notification — while other alert types worked. Offline rules now
retain Duration samples (cycle rules still keep 1, matching their last-sample
lookback).
Fixes the prior over-correction in RetentionWindow; corrects the test that
had pinned the buggy offline=1 value, and adds offline + combined-rule
regression tests driving the real trim loop.
The v2.2.2 Release workflow failed: fetch-frontends.sh fetched user-dist
from hamster1963/nezha-dash-v2 at v2.1.1, but upstream went v2.1.0 -> v2.1.2
and never tagged v2.1.1, so the dist.zip download 404'd and unzip aborted the
build. Point at the existing v2.1.2 asset.
Add TestCheckStatus_SampleMemoryBounded asserting that, across 100k ticks,
the per-(alert,server) sample slice length and capacity stay bounded by the
rule's retention window and never grow with elapsed time.
Trim alert samples using AlertRule.RetentionWindow() (max rule duration)
instead of Check()'s verdict max, which is 0 while a rule's window is still
filling. The old max<=0 trim wiped history every tick, so Duration>=2 general
rules never accumulated enough samples and never fired a notification.
Add model + end-to-end singleton regression tests covering sample
accumulation, the retention-window contract, and the actual notify path.
Decouple OAuth2 callback host from agent install host. When dashboard_host
is empty, the request Host is passed through; otherwise non-reserved hosts
are pinned to dashboard_host. Added to reserved-host allowlist for NAT.
After #1197/#244 a new agent emits both hyphenated and underscore credential
metadata, so a new dashboard receives both at once. Add tests for the everyday
both-present case and pin that the hyphenated key takes precedence over the
underscore alias that Caddy v2.11.4 strips.
A general alert rule with Duration:0 (accepted by the API, no minimum
validation) drove fail*100/total with total==0, panicking with an integer
divide-by-zero inside checkStatus, which has no recover and would take down the
whole alert goroutine — a config-reachable DoS by any user able to create alert
rules. Skip duration<=0 rules in Check via continue (not boundCheck, which would
pollute hasPassedRule and skip sibling valid rules). Also trim the sample slice
when max<=0 in alertsentinel, otherwise it appended every tick without ever
trimming. Adds regression tests for zero-only and mixed rule sets.
GHSA-jg62-j5h6-8mpq: the terminal and file-manager endpoints created unbounded
IO streams; an authenticated member could open thousands, each spawning
goroutines, a 1MiB buffer and an agent-side PTY, exhausting dashboard and agent
resources. CreateStream now enforces a per-user (20) and per-server (40) cap in
the existing ioStreamMutex critical section, using the stream map as the single
source of truth. Dashboard-internal streams (uid==0: NAT, server transfer, MCP
transfer) skip the per-user cap but still count per-server. Adds caps,
exemption, slot-release and no-leak regression tests.
GHSA-9rc6-8cjv-rcvx: getRedirectURL derived the OAuth2 callback URL from the
raw Host header, so a forged Host (or a provider with loose redirect-URI
matching) could divert a victim's authorization code to an attacker origin and
bind their identity. Trust the request Host only when it is an operator-declared
dashboard host (IsReservedDashboardHost, same allowlist guarding NAT routing);
otherwise fall back to the configured InstallHost.
