Decided by A reference pointing at the upstream fix: a commit, a PR, a Red Hat bug
Finding A reference points at an upstream fix (commit tier): https://github.com/shopizer-ecommerce/shopizer/commit/197f8c78c8f673b957e41ca2c823afc654c19271. That makes this CVE a candidate for an ARMR patch rule — it is the kind of defect ARMR can address, and there is a fix to work from. No rule exists and none is scheduled: writing one means reading the linked change and finding a hook point ARMR can express it at, which may turn out not to exist.
