Microsoft Edge vulnerability
Memory corruption vulnerability in Microsoft Edge's Chakra JavaScript engine allows remote code execution or denial of service through malicious web content.
Verdict
Today item — known-exploited.
A remote attacker can execute arbitrary code or crash the browser by crafting a malicious website that triggers memory corruption in the Chakra engine. The vulnerability is actively exploited in the wild.
01
Is it exploitable?
— the evidence, ranked above the scoreExploit available
Public proof-of-concept exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported 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 2022-03-28).
Probability (EPSS)
EPSS 0.8249 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Microsoft, Edge. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-119 Memory Buffer Bounds Error — weakness family: Memory safety.CWE assignment from the public NVD record; the weakness class drives how the flaw is exploited.
02
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 webpage containing JavaScript that exploits memory corruption in the Chakra engine.
Business
User visits the webpage and the browser crashes or becomes unstable, disrupting productivity.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I trigger the memory corruption vulnerability to achieve arbitrary code execution within the browser process.
Business
Attacker gains code execution in the user's browser context, enabling data theft or lateral movement to the host system.
3
Lateral reach — past segmentation narrative 3
Attacker
I use the code execution to exfiltrate sensitive data or install malware on the victim's machine.
Business
Organization faces data breach, credential compromise, or endpoint infection requiring incident response and remediation.
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.
