Adobe Flash Player vulnerability
Adobe Flash Player contains a double free vulnerability allowing remote code execution. The flaw has been exploited in the wild.
Verdict
Today item — known-exploited.
A double free memory corruption flaw in Flash Player enables unauthenticated remote attackers to achieve arbitrary code execution through crafted content, with active exploitation confirmed.

Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
4 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 2024-09-17).
Probability (EPSS)
EPSS 0.24204 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 8.8 (CVSS:3.1/AV:N/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.
Weakness (CWE)
Mapped to CWE-399 Resource Management Errors — weakness family: Resource / availability.CWE assignment from the public NVD record (may be stale); the weakness class drives how the flaw is exploited.
CISA SSVC (triage disposition)
Exploitation: active · Automatable: yes · 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 3861 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.

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 malicious Flash content that triggers a double free condition in the player's memory management.
Business
Users visiting attacker-controlled or compromised websites are exposed to code execution without warning or user interaction.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I exploit the memory corruption to overwrite heap structures and gain control of program execution flow.
Business
Attackers achieve arbitrary code execution in the context of the browser, bypassing sandbox protections.
3
Lateral reach — past segmentation narrative 3
Attacker
I execute malware, steal credentials, or establish persistence on the victim's system.
Business
Organizations face data theft, system compromise, and potential lateral movement within their networks.
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.
