Continuous DNN advisory coverage — not a single-CVE feature

DNN Defender 03.03.00 does not protect only CVE-2026-40321. Its release knowledge base contains all 47 official DNN Platform advisories synchronized through 25 August 2026. Security Risk Analysis compares the running DNN build with the authoritative affected range for every entry, avoids the false “predates the fix” result on newer versions, and shows the control state beside the exposure.

The authoritative upstream index is the DNN Platform Security Advisories page. The packaged catalog is used locally at runtime; customer requests and site details are not sent to GitHub for this comparison.

Latest official DNN advisories

The most recent upstream release group was published on 25 August 2026. These entries had GHSA identifiers at synchronization time; a CVE may be assigned later without changing the underlying Defender coverage mapping.

The same release group also includes private Journal interaction, restricted-file metadata, profile-picture privacy, and optional HTML-module JavaScript restriction advisories. Security Risk Analysis displays all of them, not only the highest-severity subset shown above.

Complete 47-advisory coverage matrix (release snapshot)

This is the packaged knowledge snapshot synchronized through 25 August 2026, not a live claim about advisories published after that date. “Targeted” means a mapped request path or exploit pattern has a dedicated Advisory Shield control; “Partial” means a documented subset is guarded; “No targeted control” means only general layers may apply and must not be presented as a virtual patch. These are catalog mappings, not proof that a request was blocked on a particular site. The Security Risk Analysis page shows the running version, affected range, current control mode, and event evidence. Install the vendor fix for the actual platform repair.

What each coverage layer can establish

Publication statement: DNN Defender assesses all advisories in the catalog synchronized through 25 August 2026. In 03.03.00, 42 map to targeted or partial controls; five have no dedicated virtual patch. A finding shows exposure, current control mode, and the actual observed or blocked outcome separately. Strict and Prevention deny a request only when a mapped control matches. A vendor-fixed DNN release remains the definitive correction for vulnerable core code.

CVE-2026-40321 is one example, not the boundary

For CVE-2026-40321, Security Risk Analysis identifies DNN <10.2.2 as affected. When the relevant controls are enabled in blocking mode and a mapped request matches, Advisory Shield Strict and WAF-UPLOAD-001 can deny SVG/SVGZ uploads at the HTTP request boundary and record the evidence. The same control architecture is also applied to authorization bypass, workflow, SSRF, private-file, remote-source, executable upload, XSS, forwarding-header, and other advisory families listed in the catalog.

Security boundary

“Covered” does not mean DNN core binaries have been rewritten. A targeted control blocks the known route/pattern; a partial control closes important exploit paths; the scanner and FIM address payload and persistence behavior. Direct disk access, memory-only/native malware, an unknown custom route, or content stored before protection was enabled may require additional investigation.

Verify Advisory Shield = Enabled + Strict, WAF = Prevention, Realtime Monitor health, a valid FIM baseline, and successful scheduled scans. Keep DNN Defender after upgrading, because future advisories, extension vulnerabilities, credentials, unsafe uploads, and configuration errors remain relevant. The vendor-fixed DNN release remains the definitive correction for vulnerable core code.
