Weekly CVE Report: Daily Cybersecurity Beats CISA KEV on Exploited Flaws

Daily Cybersecurity flagged nine actively exploited vulnerabilities before or beyond CISA this week. That is the standout finding from the latest CVE WATCHTOWER report, spanning August 31 to September 6, 2026. The tracker also logged 2,316 new CVEs over the same period. This weekly CVE report puts the two feeds side by side, so you can measure the intelligence lead time in days.

The week in numbers

Volume set the backdrop this week. CVE WATCHTOWER recorded 2,316 fresh disclosures across the seven-day window. Of those, 271 rated critical, and another 708 landed as high severity. So roughly a thousand new flaws demand near-term attention.

Yet counts alone do not equal risk. Confirmed exploitation does. Daily Cybersecurity’s intelligence sources marked nine flaws as ACTIVE this week. Five of them reached CISA’s Known Exploited Vulnerabilities (KEV) catalog a day later. The other four never made the KEV catalog at all.

The intelligence lead: Daily Cybersecurity vs CISA KEV

The table below compares when Daily Cybersecurity marked each flaw exploited against the official CISA KEV “date added.” The lead-time column shows the gap. Four flaws remain exclusive to Daily Cybersecurity, since CISA has not listed them.

The pattern is clear. On every flaw the two feeds share, Daily Cybersecurity flagged the exploitation a full day ahead. More striking, four critical bugs surfaced only through Daily Cybersecurity. A team waiting on CISA KEV alone would have missed those entirely.

Exploited vulnerabilities from CISA KEV only

These five exploited vulnerabilities appear on CISA KEV but not in Daily Cybersecurity’s ACTIVE feed this week. Each still warrants urgent patching. The “CISA KEV date added” column reflects the official catalog.

The flaws that stand out

SonicWall gateways under active attack

Two SonicWall bugs led the shared list. CVE-2026-83548 is a pre-authentication SSRF rated a perfect 10.0. Paired with the command-injection flaw CVE-2026-83549, it opens a path to unauthenticated code execution. SonicWall confirmed live attacks, and Daily Cybersecurity flagged both a day before CISA. Since SMA1000 gateways face the internet, exposed units need an immediate review.

AI tools and WordPress plugins hit hardest

The four DC-exclusive flaws show why early intelligence matters. VulnCheck watched the Langflow bug draw hundreds of attacks that harvest OpenAI and AWS keys. Wordfence, meanwhile, blocked roughly 200,000 attempts on Elementor Pro and over 440,000 on the Super Forms plugin. Both plugin flaws let unauthenticated visitors upload a web shell. None of these four sit on CISA KEV yet.

What defenders should do

Prioritize by exploitation, not by score alone. First, patch the internet-facing SonicWall, JFrog, and Switchvox systems. Next, update every affected WordPress site and inspect upload folders for stray PHP files. Then patch Chrome to close the V8 drive-by bug. Finally, secure the Langflow, LiteLLM, Kestra, PaperCut, and Starlette instances on your network.
