A Grype scan of the backend image reported 1576 findings, 16 critical. Most came from build headers nothing uses: every requirement ships a wheel (xmlsec and lxml bundle their own libxml2 2.14), so libxml2-dev, libxmlsec1-dev, libsasl2-dev, libldap2-dev, libssl-dev and pkg-config only pulled in linux-libc-dev (1161 findings), libunbound8 and Debian's libxml2. The rest were Debian fixes the python:3.11-slim base had not picked up yet (perl, libc6, gzip, pcre2, sqlite, libevent) and old pip / setuptools / wheel. The image now runs apt-get upgrade, upgrades pip, setuptools and wheel, and installs requirements with --only-binary=:all:, so a requirement without a wheel fails the build instead of needing a compiler. Rebuilt image: 187 findings, none critical, no High with a fix available; the remaining fixable ones are Python 3.11 CVEs fixed only in 3.13+. App import, SAML/xmlsec and the test suite run inside the image.
