Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Sunday's disclosure activity reveals 4 critical vulnerabilities (CVSS 9.0+), representing a 64% decrease from the prior day's 11 critical issues. High-priority vulnerabilities also declined substantially, with 34 disclosed compared to 71 previously, a 52% reduction. Four actively exploited vulnerabilities (KEV) require attention, including legacy threats targeting Microsoft Office (CVE-2009-0556), MongoDB Server (CVE-2025-14847), and HPE OneView (CVE-2025-37164). Notable critical disclosures include CVE-2025-65091 affecting XWiki Full Calendar Macro with a maximum CVSS 10 score, CVE-2026-22688 in WeKnora with CVSS 9.9, and CVE-2026-61686 impacting React Router. With 0% patch availability currently reported, organizations should prioritize compensating controls and monitoring until vendor patches are released.

  • 4 critical vulnerabilities disclosed, 64% decrease from prior day
  • 34 high-priority vulnerabilities, 52% reduction from previous 71
  • 4 actively exploited vulnerabilities targeting Microsoft Office, MongoDB, HPE OneView, and Digiever systems
  • 0% patch availability indicates compensating controls needed
  • XWiki, React Router, WeKnora, and OpenProject among affected products

Immediate action: Organizations using Microsoft Office, MongoDB Server, HPE OneView, or Digiever DS-2105 Pro should prioritize review of the four actively exploited vulnerabilities. With no patches currently available for Sunday's disclosures, implement network segmentation, enhanced monitoring, and access restrictions for affected systems until vendor remediation guidance is released.

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.
