CVE-2023-23488 is detected at
classes/class.memberorder.php:936:getMemberOrderByCode -- the exact line
verified in the source, in unmodified Paid Memberships Pro 2.9.7.
A two-file slice carrying both ends of the CVE, 2885 lines, loads and
queries in 122 seconds and reports 16 entailed injection findings.
**The other fifteen are not noise.** The file holds 26 `$wpdb` query calls
and **zero** of them use `->prepare`; all 26 interpolate or concatenate a
variable. The engine reports 16 of 26, so it under-reports rather than
over-reports, and every sampled finding is a genuine unprepared query --
`get_row("... WHERE id = '$id'")`, `get_var("... WHERE ID = '" .
$this->user_id . "'")`. CVE-2023-23488 is simply the instance that got an
identifier, because it is reachable unauthenticated; the rest are the same
defect with different reachability.
That answers the question that prompted this: whether the system can find
one real CVE. It can, in production code, at the exact line, in two
minutes, for a cent. What it could not do was survive its own plumbing at
637 files -- four separate quiet failures on this one checkout, all between
the scan and the arbiter, none of them in the analysis.
What this does NOT settle is recorded with it: the full checkout still does
not load and that boundary is unmeasured; whether php2cpg resolves
`new X()` and `$this->method()` is still unknown, since this slice reached
the sink through a same-function flow rather than across the object; and
one CVE on one plugin is not the class-by-class table over several plugins
that 5.8 asks for.
On cutting the input with a model, proposed when size looked like the
blocker: the evidence argues for scoping rather than triage. Two of 637
files found the CVE, task 2.10 already scopes by what a project declares it
ships, and diff-scoping is this spec's thesis. A model choosing what to cut
adds a fifth quiet-failure surface -- drop the file holding the bug and the
scan reports clean with nothing recording why, which is the shape of all
four failures found today. The reverse direction is where it fits: ranking
which regions get the budget, not choosing what to remove.
