# Rule Outcome Status Detail

identity: Does this identifier describe a vulnerability at all? first match wins

1 rejected no-match CVE Program withdrawal of this identifier

scope: Is the vulnerability ARMR's to address? first match wins

2 armr-patch-file no-match An ARMR patch file on disk for this CVE

3 armr-secure-rule-file no-match An ARMR security-rule template on disk for this CVE

4 manual-classification no-match A researcher's recorded decision for this specific CVE

5 manual classification no-match Manual classification of this CVE in the legacy dataset

6 non-java-upstream no-match A root cause in non-Java code: an OS kernel, a C library, or a bundled runtime

7 oracle-component no-match The defect being in a component of a tracked product the agent does not reach: JavaFX, the Java SE installer, the native WebLogic proxy plug-in. Oracle gives these no CPE of their own and names them only in the description.

8 osv-maven no-match An OSV.dev record of this CVE affecting a package published to Maven Central

9 cna-maven-package no-match An affected Maven artifact named by the CNA itself

10 known-cpe-product no-match An NVD CPE naming a product ARMR tracks

11 cna-cpe-product no-match A CPE the CNA published naming a tracked product. Oracle publishes these on advisory day, months before NVD.

12 oracle-advisory-family no-match A tracked product family named in Oracle's own risk matrix. CPE cannot carry a suite name, only a module.

13 non-deployable-product no-match The only affected product being a sealed appliance image, where Java runs but no -javaagent can be attached

14 unmatched-product decided it matched Not applicable No tracked product matched

disposition: What do we do about one that is? cumulative: every rule gets a turn

17 poc-derivable not-reached An indexed exploit to reverse-engineer, where there is no source to read

18 no-exploit not-reached With no fix path, a public exploit, or a CISA record of one

19 secure-rule-match not-reached A vulnerability class already blocked by an ARMR security rule

20 below-action-threshold not-reached Medium or Low severity, no KEV listing, no PoC clearing the evidence bar, no CISA verdict, no Oracle advisory

21 no-exploit-published not-reached A published working exploit for this candidate, not only a proof of concept, a forecast, or nothing at all
