Apple iOS, iPadOS, and macOS vulnerability
A use-after-free vulnerability in WebKit affects Apple iOS, iPadOS, and macOS, allowing remote code execution through maliciously crafted web content.
Verdict
Today item — known-exploited.
This vulnerability enables attackers to achieve arbitrary code execution on affected Apple devices by exploiting memory safety defects in WebKit's HTML processing. Active exploitation in the wild increases risk for all users of Safari and WebKit-dependent applications.
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
6 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 2022-02-11).
Probability (EPSS)
EPSS 0.16342 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Apple, iOS, iPadOS, and macOS. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-416 Use After Free — 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
Craft malicious web content that triggers use-after-free conditions in WebKit's HTML parser
Business
User devices become compromised with arbitrary attacker code execution, risking data theft and system control
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
Host the malicious content on attacker-controlled or compromised websites to reach victims
Business
Widespread device compromise across Safari users and applications relying on WebKit, damaging Apple's security reputation
3
Lateral reach — past segmentation narrative 3
Attacker
Execute arbitrary code with the privileges of the affected application or user session
Business
Attackers gain access to sensitive user data, credentials, and system resources on millions of devices
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.
