None of the signals that would put it in front of an engineer is present, and the volume of CVEs below that bar is too great to take one at a time, so no rule is written for it. This is a decision about what we act on, not a finding that the CVE is harmless — a patch may well be derivable, and a low-severity defect can still be one link in a longer chain.","verdicts":[{"rule":"rejected","stage":"identity","outcome":"no-match"},{"rule":"armr-patch-file","stage":"scope","outcome":"no-match"},{"rule":"armr-secure-rule-file","stage":"scope","outcome":"no-match"},{"rule":"manual-classification","stage":"scope","outcome":"no-match"},{"rule":"h2-history","stage":"scope","outcome":"no-match"},{"rule":"non-java-upstream","stage":"scope","outcome":"no-match"},{"rule":"oracle-component","stage":"scope","outcome":"no-match"},{"rule":"osv-maven","stage":"scope","outcome":"matched","status":"QUEUED-FOR-REVIEW","detail":"Maven packages: org.jenkins-ci.main:jenkins-core"},{"rule":"patch-hint","stage":"disposition","outcome":"matched","status":"MITIGATION-CANDIDATE","detail":"References include candidate fix URL (commit tier): https://github.com/jenkinsci/winstone/commit/410ed3001d51c689cf59085b7417466caa2ded7b.patch"},{"rule":"open-source-maven","stage":"disposition","outcome":"skipped"},{"rule":"poc-derivable","stage":"disposition","outcome":"skipped"},{"rule":"no-exploit","stage":"disposition","outcome":"skipped"},{"rule":"secure-rule-match","stage":"disposition","outcome":"no-match"},{"rule":"below-action-threshold","stage":"disposition","outcome":"matched","status":"NO-EXPLOIT-PUBLISHED","detail":"LOW severity, no KEV listing, no public PoC clearing the evidence bar, no CISA exploitation finding, and not in an Oracle advisory — none of the signals we act on is present.","decisive":true},{"rule":"no-exploit-published","stage":"disposition","outcome":"skipped"}],"patchHintUrl":"https://github.com/jenkinsci/winstone/commit/410ed3001d51c689cf59085b7417466caa2ded7b.patch","patchHintTier":"commit","affectedProducts":[{"vendor":"jenkins","product":"jenkins","isKnown":false,"cpe":"cpe:2.3:a:jenkins:jenkins:1.409.1:*:*:*:lts:*:*:*"}],"affectedPackages":[{"name":"org.jenkins-ci.main:jenkins-core","introduced":"0","fixed":"1.409.3"},{"name":"org.jenkins-ci.main:jenkins-core","introduced":"1.410","fixed":"1.438"}]},"assessment":{"record":{"state":"active"},"protection":{"level":"none"},"action":{"state":"unverified","type":"patch-rule"},"review":{"state":"automated","basis":"upstream-data"}},"signals":{"hasPOC":false,"pocCount":0},"kev":{"inKEV":false},"epss":{"available":true,"score":0.01231,"percentile":0.6732},"ssvc":{"available":false},"patchHintUrl":"https://github.com/jenkinsci/winstone/commit/410ed3001d51c689cf59085b7417466caa2ded7b.patch","patchHintTier":"commit"}
