Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Yesterday's disclosures revealed only 2 critical vulnerabilities, a 91% decrease from the prior day's 22 critical issues. High-priority CVEs dropped 47% to 53, indicating lighter weekend disclosure volume. Five actively exploited vulnerabilities require attention, including CVE-2025-14847 affecting MongoDB, CVE-2026-20805 targeting Microsoft Windows, and CVE-2025-37164 impacting HPE OneView. The critical issues CVE-2025-10484 and CVE-2025-15403 both affect the RegistrationMagic WordPress plugin with privilege escalation flaws. Patch availability stands at 0%, requiring organizations to implement compensating controls until vendor fixes become available.

  • 2 critical CVEs disclosed, down 91% from 22 the prior day
  • 53 high-priority CVEs, a 47% decrease from 100 previously
  • 5 actively exploited vulnerabilities affecting MongoDB, Microsoft Windows, HPE OneView, Microsoft Office, and Gogs
  • 0% patch availability requires alternative mitigations
  • WordPress RegistrationMagic plugin contains two critical privilege escalation flaws

Immediate action: Organizations running MongoDB, Microsoft Windows, HPE OneView, Microsoft Office, or Gogs should review exposure to the five actively exploited vulnerabilities. With no patches currently available for yesterday's disclosures, implement network segmentation and access controls as interim mitigations.

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.
