channel: cap the per-channel invite set (maxinvites, default 100) — it only shrank when the invitee joined, so an op could grow it unboundedly; re-inviting an already-listed nick still works

|
dnsbl: cap the number of blocklist zones checked per client at 16 — each zone is a serial blocking DNS lookup, so a long (mis)configured zone list could stall a connecting client's registration for zones.len()*timeout

|
metrics: set read/write timeouts on each scrape connection — the single-threaded accept loop did an untimed read, so one client that connected and never sent blocked every future scrape (slowloris)

|
metadata: prune a channel's metadata once the channel no longer exists (tick GC) — #channel entries were never freed (unlike user entries on quit), so setting metadata on a channel that later empties leaked memory and kept re-persisting to disk forever; +P channels stay live so keep theirs

|
snoop: gate the per-connect/join/quit eprintln! behind snoop_stderr (default off) — it wrote to stderr (journald) on every client event in the reactor thread, unbounded under a connect flood; the +c/+q snotices already carry the operator-facing signal

extbanbanlist: identify extbans by the real rule (<letter>:...) instead of "2nd byte is a colon" — the old heuristic wrongly skipped a plain hostmask whose second char happened to be ':', mis-listing it

captcha: clamp recaptcha/cloudflare token TTL to [60s, 86400s] — an unclamped conf value could set exp in the past (every token instantly invalid, self-DoS) or absurdly far out

|
geoip: bound recursion + require forward progress in the .mmdb value decoder — value_len/map_get recursed into nested maps/arrays with no depth limit (unlike resolve), so a crafted database could overflow the stack or spin on a zero-advance value; cap nesting at 32 and bail on a malformed (0-length) sub-value

|
connclass: resolve hash= independently of token order — the fold only ran if password= had already been parsed, so "hash=sha256 password=<hex>" (hash first) stored the digest as a plaintext password and every login to that class failed; build() now combines <algo>:<digest> after the full token pass

|
permchannels: isolate the load-time mode applier in catch_unwind so a panicking mode handler can't leave mode_sudo stuck true — which would silently disable rank/oper gating for every subsequent MODE; the flag is now always reset

|
multiline: reject an over-limit batch with a FAIL instead of silently dropping the overflowing lines — accumulate() dropped a line that exceeded multiline_maxbytes/maxlines but still returned buffered=true, so the client believed a truncated message was sent whole; now overflow flags the batch and close() drops it with a standard FAIL

|
connflood: bound the per-IP connection-history map (prune stale buckets past 65536 tracked IPs) — it only shrank on the tick GC, so a wide source-IP spread could grow it unbounded between ticks (memory DoS)

|
rpc: authenticate on the header block before buffering the request body — the httpd read up to MAX_REQUEST (256 KiB) and only then checked the Authorization header, so an unauthenticated peer reaching rpc_bind could make each connection consume memory + a worker thread; now POST+auth are validated as soon as headers are complete, before any body is read

|
rpc: refuse an all-wildcard x-line via ban.add — the mask went unvalidated, so an authenticated RPC call with "mask":"" or "*@*" installed a K/G/Z-line matching the entire network; require at least one literal host/ip/nick char
|

|
password_hash: reject a PBKDF2 credential with an absurd iteration count (>10M) instead of running it — the count is read straight from the stored string, so a corrupt/hostile credential (e.g. via a compromised accounts backend) could pin a worker thread for a very long time; legitimate work factors are far below the cap

|
oper: gate the client-facing SVSLOGIN/SVSLOGOUT behind oper_svslogin (default off) — they were a pre-S2S stopgap that let any oper forge an arbitrary account login (set_login) and thus +r/account-gated access; the live path is S2S link_svslogin (source_is_service-gated), so services are unaffected — only the obsolete oper backdoor is closed

perf: S2S channel-message fanout shares the line by Arc across members (relay_channel_message) instead of cloning a String per recipient — mirrors the client PRIVMSG fanout; builds at most three variants (plain / server-time / echo-services-tagged) whatever the channel size, behaviour unchanged

|
perf: glob_match takes a zero-allocation byte-wise path for ASCII operands (the norm for hostmasks/IPs/cloaks) instead of collecting two Vec<char> per call — it runs per-message (filter), per-user (extbans/tline) and per-channel (channelban); non-ASCII still uses the Unicode-lowercased fallback, and a proptest pins the two paths equal on ASCII

|
whoisport: report the port the user actually connected to (User.port, set at accept) instead of conf("bind")/conf("bind_tls") — those are Vec-valued so conf() returned only the LAST configured listener, giving every user the same wrong port on a multi-listener server

|
syslog: strip control chars (CR/LF) from the message before framing — a snotice carrying user-influenced text (nick/realname/quit reason) with an embedded newline could inject a forged syslog record; matches the CR/LF care the JSON log path already takes

|
filehost: refuse to sign upload tokens when filehost_jwt_secret is unset/empty/"changeme" — the default fell open, signing with a world-known key so anyone could forge a server-trusted upload authorization; now it fails closed and tells the user to fix the config

|
auth: constant-time compare for VHOST and WEBIRC secrets — both used plain == on the config password, unlike oper/RPC/JWT secrets which already route through ct_eq; expose password_hash::ct_eq as the shared comparator and use it (usernames stay plain == — not secret)

|
mode: cap mode changes per MODE command (modes=, default 20) and advertise it as the MODES= ISUPPORT token — an uncapped modestring like MODE #c +bbbb… dispatched a handler per letter, each fanning out to the whole channel and every S2S link (amplification DoS); matches InspIRCd's MODES limit

|
s2s/xline: reject a malformed ADDLINE duration instead of coercing it to 0 (= a silent permanent ban), and make add_xline expiry saturating (n.saturating_add) so a peer sending duration=u64::MAX can't overflow-panic the debug build or wrap in release

|
http: bound spawn_http concurrency (http_max_concurrent, default 32) like spawn_crypto — it spawned one unbounded OS thread per call, so a pre-auth VERIFY/REGISTER flood could exhaust threads and hammer the accounts backend; at capacity the command now fails with TEMPORARILY_UNAVAILABLE instead

|
http: verify TLS certs by default + cap the response body — set_verify(NONE) unconditionally let a MITM read/forge the account-registration & captcha traffic (usernames, emails, plaintext passwords) POSTed to operator-configured https URLs; now the connector's cert+hostname check stays on (opt out with http_tls_verify=no), and read_to_end is bounded to 4 MiB so a hostile endpoint can't OOM the worker

denychans: bound redirect recursion — a badchan redirect re-enters Server::join (which re-runs denychans), so a redirect loop (#a->#b->#a) or a redirect into a broad badchan glob recursed until the single-threaded daemon stack-overflowed from one JOIN; cap the chain at 8 hops via a RedirDepth guard in ext

connectban: clamp the IPv6 keep-hextets to >=1 — connectban_ipv6cidr between 1 and 15 made keep==0, so the z-line glob became "*" and banned every IPv6 address on the internet (and bucketed all v6 clients into one key); mirrors the v4 clamp(1,4)

|
webirc: require a non-empty source-IP mask on a webirc block — an empty ipmask meant "any IP", so a maskless webirc=<password> block turned one shared secret into a full host/IP spoof (bypassing z-lines, DNSBL, GeoIP, cloak) for anyone who learned it; now the gateway's connecting IP must match the block's ipmask

f56b68d6f5
|
resolver: close an off-path DNS spoof — connect() the UDP socket so the kernel drops replies from any IP but the nameserver, and use a CSPRNG per-query transaction id instead of the hardcoded 0x4543/0x4544 (which were in the public source, so rDNS/DNSBL answers could be forged with no guessing)

s2s: validate a message source actually lives behind the link it arrived on (source_behind) before applying remote JOIN/IJOIN/KICK/TOPIC/MODE/KILL/PRIVMSG — else a peer could forge ops/kicks/bans/topics/service-badged messages for users behind another link; NICK/QUIT/PART already guarded this, now the channel-state handlers do too
