- Around line 637-646: Build separate top-finding lists for the critical and KEV
events instead of sharing topFindings: preserve up to three critical findings
for dispatchCveCriticalDetected, and independently select up to three new KEV
findings for dispatchCveKevDetected. De-duplicate KEV findings by finding
identity, not severity, so a KEV finding that is also critical remains eligible
and every KEV webhook includes an actionable CVE when one exists.
- Around line 607-612: Propagate webhook delivery failures from
WebhookDispatcherService.dispatchEvent through the Pro and Enterprise CVE
wrappers to dispatchCveEvents, setting dispatchedOk to false when any required
delivery fails. Preserve the new scan result for Fleet and Prometheus while
retaining the previous alerting baseline so failed findings are retried.
In `@apps/api/src/prometheus/prometheus.service.ts`:
- Line 767: After the awaited getCveScanResult call in the CVE metrics update
flow, revalidate that the connection’s current state is still the same state
being updated and that its connection label remains valid before recreating or
updating CVE gauges. Abort the stale update when cleanup has replaced or removed
the state, preserving cleanupConnectionMetrics behavior.
In `@apps/web/src/components/pages/security/CveAlertBanner.tsx`:
- Line 40: Update the CVE ID collection in CveAlertBanner to de-duplicate IDs
after priority sorting and before limiting the results with slice(0, 3).
Preserve priority order, ensure distinct IDs reach the badge row, and keep the
resulting React keys unique.

Reviewed the full diff. Solid shape overall — the fire-on-change diffing, the identity-based finding key, the baseline-on-first-scan rule and the label cleanup in the Prometheus exporter are all the right calls, and the docs are unusually complete for a feature PR.
Two findings make the feature silently not work in production, and both are invisible to the test suite because cve-scan-dispatch.spec.ts builds the service with Object.create(prototype) + Object.assign rather than through DI or the real dispatcher:
otelEventsis imported withimport type, so Nest can never inject it — the OTel mirror never emits.dispatchCveEventscan never returnfalse, becauseWebhookDispatcherService.dispatchEventswallows every error — so the documented "preserve the baseline for retry" guarantee is dead code and a failed delivery loses the alert permanently.
A third one is a behaviour regression outside the CVE feature: the new Fleet rollup read sits inside the 5s per-instance timeout. Details inline; the rest are smaller.
|
All the above findings are addressed in a9d2487 .

CI failure is unrelated to this PR — all fails are workspace-broker specs, while every suite this PR touches passes locally and in this same run. |

Re-reviewed a9d2487. Thanks, the fixes are solid: the OTel value import, delivery status returned from the dispatcher, the parallel 1s-bounded Fleet read, de-duplicated topFindings, the partial-scan dispatch, the banner wording and the renamed alert rules all address the earlier threads.
Three things are still open, inline: the retry fix now causes duplicate sends and leaves the stored scan stale, removing the partial-scan gate re-alerts known module CVEs after a transient MODULE LIST failure, and the Prometheus change still reads storage on every tick.

@Kathircpe could you rebase this onto master? It's 13 commits behind. The red There's also still one open thread from my review to close out before this is ready. |
…tric cleanup - Diff on cveId+node identity with explicit KEV-flip and escalation-to-critical transitions (no missed KEV, no reclassification spam, scale-out pages) - Hoist OTel mirrors out of license gates so OSS+OTLP sees events - First scan establishes baseline silently; partial scans never dispatch; dispatch-before-save preserves baseline for retry - Remove CVE gauge series on missing scan, re-address, and connection cleanup; legacy-safe missingSources handling - Docs: connection labels, baseline and dual-delivery notes; banner counts/badges from a single source
…pe, unified finding type - Split webhook topFindings per event so 3+ criticals can't starve KEV entries out of the KEV payload (KEV deduped by CVE id) - Skip CVE gauge writes when cleanup ran during the storage await (identity + label check), with deferred-storage race test - De-duplicate banner CVE ids across cluster nodes (unique badges/keys) - Alias CveWebhookFinding to CveWebhookFindingSummary; drop the unused CveWebhookData; assert payload fields and connectionId passthrough in dispatch specs
…aths honest - fix OTel DI (value import), dispatcher now returns delivery success so CVE baseline preservation works; fleet CVE read overlaps probes with its own timeout - dedupe critical topFindings, dispatch partial scans with partial:true instead of muting, memoize Prometheus CVE gauges with CVE_ENABLED gate - clarify banner counts, rename Alertmanager rules to Present semantics and add CveDatasetStale
…gs, throttle CVE reads - dispatcher: RETRYING hands off to retry processor; baseline holds only for FAILED/DEAD_LETTER/throw - cve diff: skip module findings while either scan has unknown inventory so MODULE LIST blips don't re-alert - prometheus: throttle CVE scan reads to 60s per connection

Thanks for the rebase — CI is green and the carry-forward in 624dd96e is a real improvement: re-validating carried module findings against the current dataset (and recomputing fixedIn) is much better than either dropping them during a blip or trusting them blindly.
One regression from the same commit, inline.

Sorry, this one got a bit messy with the scope and review iterations 😅 |

cec75174 fixes it the right way: prevUncarriedUnknown suppresses module findings only for nodes that had nothing to carry, so nodes that did carry keep the identity-based diff intact. The new spec pins the blip-baseline sequence and still asserts a genuine new finding dispatches once, and the product-change case falls out of the same guard rather than needing its own.
Everything from both rounds is addressed and CI is green. No need to apologise for the iterations — the alerting semantics here are genuinely fiddly, and the result is a lossless diff with honest quiet paths.
