Typing --from/--to/--image by hand means someone has to remember the recipe also
bumped its redis. That is how sidecar CVEs went uncounted for months. Point this
at a PR's compose.yml and it reads the windows off the diff instead.
advisory-scan.py plausible --compose-to <.../branch/<pr>/compose.yml>
-> community-edition: v2.0.0 -> v3.2.1
-> clickhouse-server: 23.4.2.11-alpine -> 24.12-alpine
-> 6 CVEs, identical to the hand-specified args
Details that mattered:
- keyed by SERVICE, not image repo. plausible moved plausible/analytics ->
ghcr.io/plausible/community-edition; keyed by repo that reads as one image
vanishing and an unrelated one appearing, and the app window - the one carrying
the critical - is lost entirely.
- the baseline is the repo's DEFAULT BRANCH resolved from the API, never assumed
to be main, because several recipes keep a stale main beside a live master.
- image names are matched against advisory sources BOTH ways: an image name is
often longer than its source repo (clickhouse/clickhouse-server vs
ClickHouse/ClickHouse) and sometimes shorter (redis vs redis/redis). One
direction silently dropped the clickhouse window.
- credentials go in an Authorization header, never the URL: in-URL creds leak
into shell history and process lists, and urllib mis-parses a password
containing a colon.
--from/--to/--image remain for finer-grained checks (scanning a window that is
not a literal compose diff). 71 tests; discourse 140 / gitea 2 / mailu 2
unchanged.
