Adobe Flash Player vulnerability
Adobe Flash Player contains an unspecified vulnerability allowing remote code execution or denial-of-service attacks. The flaw has been actively exploited in the wild.
Verdict
Today item — known-exploited.
This vulnerability poses significant risk due to high exploitability (EPSS 0.92) and confirmed active exploitation. Remote attackers can execute arbitrary code or disrupt service through unspecified attack vectors in Flash Player.

Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
5 independent public reports of in-the-wild exploitation are cataloged.Distinct reporting sources (vendor, incident response, government); open them for the underlying claims.
Exploited in the wild
Listed in the CISA Known Exploited Vulnerabilities catalog (added 2022-06-08).

Severity / affected
CVSS 7.8 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) · Affected: Adobe, Flash Player. Confirm exact fixed builds in the vendor advisory.CVSS — CISA-assigned via the ADP container (CVE.org), version 3.1; the CNA left no metrics, so CISA's own score is used ahead of NVD.
CISA SSVC (triage disposition)
Exploitation: active · Automatable: no · Technical Impact: totalCISA's own stakeholder-specific triage inputs, published in the CVE record (CISA Coordinator role). NOTE: this is CISA's three decision points; the final Act/Attend/Track decision also requires a Mission & Well-being input not published here, so no overall decision is asserted.
Currency of the record
CISA added this to its KEV catalog 4103 days after the CVE record was published.KEV lag = CISA-KEV dateAdded − CVE.org datePublished; a floor on how long the known-exploited flaw sat in the public record before the federal catalog listed it. Severity/weakness here is CNA- or CISA-assigned (current at disclosure), independent of NVD's analysis backlog.
Public exploit available
Public exploit tooling is catalogued for this CVE (a functional/weaponized public exploit). Catalog entries: Metasploit module. We link the catalog page(s) only — no payload or code is hosted or restated here.Link, never host — the catalog page is the source; basicsecurity.net does not redistribute payloads.

Who’s exploiting it?
— attribution turns risk into urgencyAttribution not established
No confirmed (advisory-backed) threat-actor attribution is established for this record. Absence of a named actor is not absence of compromise — see Coverage & confidence.
03
Why it matters
— the attack path, told twice: adversary, then board1
Front door — unauthenticated access narrative 1
Attacker
I craft a malicious Flash file or web page embedding vulnerable Flash content to deliver my payload to target systems.
Business
End users face compromise of workstations, data theft, and lateral movement into corporate networks through compromised endpoints.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I trigger code execution on the victim's machine when they view or interact with my malicious content in a browser.
Business
Organizations experience unauthorized access to sensitive data, intellectual property theft, and potential system takeover.
3
Lateral reach — past segmentation narrative 3
Attacker
I establish persistence or pivot to other systems on the network using the initial code execution foothold.
Business
Incident response costs, system downtime, regulatory compliance violations, and reputational damage accumulate across the organization.
04
What to do
— defensible action- Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
Say it to the boardA vulnerability with this evidence profile is a defensible budget line, not a backlog ticket — fund the change against the proof above.
