Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Monday's vulnerability disclosures center on multiple Microsoft Windows and Office flaws alongside critical smart home infrastructure weaknesses in eNet SMART HOME servers. The brief includes 4 critical-severity CVEs (up 33% from Sunday) and 10 high-priority issues (down 63%), reflecting a lighter but more concentrated disclosure day. Notable critical entries include CVE-2026-26369 and CVE-2026-26366, both CVSS 9.8 remote code execution flaws in eNet SMART HOME servers, alongside CVE-2026-1490 (CVSS 9.8) targeting WordPress installations. Microsoft dominates the actively exploited category with six Windows and Office vulnerabilities confirmed under exploitation, while legacy flaws in GitLab, FreePBX, and Notepad++ also appear on the KEV list. No patches are currently available for disclosed vulnerabilities, making compensating controls and network segmentation essential in the interim.

  • Microsoft Windows and Office account for 6 of 14 actively exploited vulnerabilities, including CVE-2026-21513 and CVE-2026-21514
  • 4 critical-severity CVEs disclosed (CVSS 9.0+), a 33% increase from Sunday's 3
  • 10 high-priority CVEs (CVSS 7.0–8.9), down 63% from Sunday's 27
  • Remote code execution dominates attack patterns, affecting eNet SMART HOME servers (CVE-2026-26369, CVE-2026-26366) and WordPress (CVE-2026-1490)
  • 0% patch availability across all disclosed CVEs — no vendor fixes released yet
  • 14 CVEs flagged as actively exploited, including legacy issues in GitLab CE/EE and Sangoma FreePBX

Immediate action: Prioritize reviewing Microsoft Windows and Office systems for exposure to the six actively exploited vulnerabilities, and isolate any eNet SMART HOME server deployments until patches are available. With 0% patch availability, apply network segmentation, restrict unnecessary access, and monitor for exploitation indicators across all affected products.

How to read this brief

CVSS score (e.g. 9.1) — severity from 0–10. Red marks critical (9+), orange high (7–8.9).

Exploitability — how hard the flaw is to attack, read from the CVSS vector:

  • Network / Adjacent / Local / Physical — how close an attacker must get. Network means reachable over the internet.
  • No / Low / High privileges — the access they need first. No privileges means no login required.
  • No interaction / User interaction — whether a victim has to do something (open a file, click a link). No interaction means fully automatable.

The lower the bar on all three, the easier to exploit at scale — “Network · No privileges · No interaction” is the worst case: hit from anywhere, no credentials, no victim action.

Actively exploited — confirmed under attack in the wild (CISA’s Known Exploited Vulnerabilities catalog). Prioritize these regardless of score.

EPSS · Nth percentile — FIRST.org’s estimated chance a flaw is exploited within 30 days. We flag it only in the top 10% — a statistical signal it’s unusually likely to be targeted, separate from whether attacks are confirmed.
