# Coraza-SPOA sidecar for haproxy-manager.

#
|

|
|
# Layout: built from upstream source. main.go is at the repo root; CRS rules
|
||
|
|
# are bundled into the binary at build time (referenced as @owasp_crs/), so
|
||
|
|
# the CRS version is whatever ships with the pinned coraza-spoa tag.
|
||
|
|
#
|
||
|
|
# Pin: review the upstream CHANGELOG (https://github.com/corazawaf/coraza-spoa/releases)
|
||
|
|
# before bumping. New tags can ship newer CRS, which can introduce new rules
|
||
|
|
# whose IDs fall into the "enforce day-one" ranges in overrides.conf — verify
|
||
|
|
# those are still high-confidence before promoting a new tag to prod.
