Three plugins, each pinned at a version whose advisory was read out of the
code, each measured against its own fixed commit:
unauth injection, sink in the receiving function pmpro FOUND
arbitrary file operation mwwpform FOUND
unauth injection across a WordPress hook wpstatistics MISSED
missing capability check -- cannot be asked
unescaped output -- cannot be trusted
Both hits are entailed by the graph alone -- no judge, no spend -- and both
disappear on the fixed side, because both fixes are calls the fact tables
carry: `$wpdb->prepare` and `realpath()`. The engine is not recognising a bug;
it is failing to find a cleansing call on a path it resolved, then finding one.
Precision is stated rather than flattered. PMPro's vulnerable side reports 15
entailed, 4 from a named parameter and 11 from the receiver, and one of those
survives into 2.9.8 at a query whose every fragment is `esc_sql`-wrapped.
The miss is the useful half, and it is checkable rather than inferred. WP
Statistics' CVE has a modelled source, a modelled sink and `esc_sql` as its
fix, and reports nothing on either side, because the file holding the sink has
zero superglobals, makes no call into the class holding the source, and is
joined to it only by
add_filter('wp_statistics_current_page', array($this, 'set_current_page'));
return apply_filters('wp_statistics_current_page', $current_page);
Both ends name the callback with a string, so no frontend can draw the edge.
Most plugin data travels this way. What the engine reports there instead is two
other sites, the same class at the wrong lines, identical on both sides -- and
not noise: upstream annotates both `// phpcs:ignore WordPress.DB.PreparedSQL`
and later rewrote one with `$wpdb->prepare`.
Two classes could not be asked at all, which is not the same as a miss.
`dominance_specs(language="php")` is empty, so missing-capability is never
asked; and `output_encoding` shares the one flat sanitizer list, which holds
`esc_sql` and `intval` but not `esc_html` -- wrong in both directions, so no
XSS verdict from this engine currently means anything.
5.10's root cause is recorded too: php2cpg's parser bridge, a race rather than
a scale limit, and the mitigation is per-file exclusion. Adds 5.11 (the hook
edge, with CVE-2022-25148 as its observable) and 5.12 (taint a field where it
is assigned, with CVE-2023-6559 as its guard).
