A path rule matched only the path as the client sent it, so /%2eenv got
past the default env-file rule while an app that decodes the path
serves /.env. A path rule now matches the path as sent or decoded once,
as a uri rule already did, and so does a path in SWWAF_TRAP_PATHS:
/%77p-login.php matches /wp-login.php. The query is cut off before the
path is decoded, and the path is decoded only once, so /%252eenv is not
/.env. A ban's notes keep the path as sent. SPEC.md and README.md say
so.
Model: opus-5-5
SWWAF_TRAP_PATHS: a request whose path, as a path rule sees it, is one
of them is a clear sign of attack, banned as a ban rule's match is; the
ban's notes give its trap_path. Checked after the rate limits, before the
rule files.
SWWAF_ERROR_BURST_THRESHOLD (default 30, or off): more refusals in a
minute after a block or ban rule or a trap path, or for a missing or
wrong token, ban the client as a broken limit does. Counted in
clients.json's minute_refusals; limit_hit error_burst, notes kind
refusals.
A token refusal is now the offence token_refused, and
smallwebwaf_offences_total counts every kind the history does.
Judgement call: the threshold is not lowered by a client's limit percentage.
