Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Thursday's vulnerability landscape shows modest activity with twelve critical vulnerabilities (CVSS 9.0+) and 100 high-priority CVEs requiring assessment. The critical CVE count decreased by one issue from Wednesday, while high-priority disclosures remained unchanged at 100 vulnerabilities. Ten actively exploited vulnerabilities continue to require priority remediation. Patch availability improved to 15%, up from 9% on Wednesday, providing security teams with more immediate remediation options as the week progresses.

  • Twelve critical vulnerabilities (CVSS 9.0+), representing an 8% decrease from Wednesday's thirteen critical issues
  • 100 high-priority vulnerabilities (CVSS 7.0-8.9), unchanged from Wednesday's count
  • Ten actively exploited vulnerabilities requiring priority remediation across enterprise and critical infrastructure environments
  • Patch availability improved to 15%, up from Wednesday's 9%, providing additional remediation options
  • Notable critical vulnerabilities include WordPress authentication bypass and Adobe Experience Manager issues requiring assessment

Immediate action: Security teams should assess the twelve active critical vulnerabilities and review the 100 high-priority CVEs for applicability to their environments. Organizations should prioritize remediation of the ten actively exploited vulnerabilities. With patch availability at 15%, teams should deploy available vendor patches while implementing compensating controls for vulnerabilities without immediate fixes.

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.
