Apple iOS vulnerability
Apple iOS type confusion vulnerability in web content processing enables remote code execution. Exploited in the wild.
Verdict
Today item — known-exploited.
Type confusion in iOS web rendering allows attackers to execute arbitrary code by delivering maliciously crafted web content. Active exploitation demonstrates immediate risk to deployed devices.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
13 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 2022-12-14).
Probability (EPSS)
EPSS 0.08523 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Apple, iOS. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-843 Type Confusion — 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 type confusion in iOS web processing engine
Business
User device compromised through web browsing without additional user interaction
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
Exploit type confusion to corrupt memory and achieve code execution within browser context
Business
Attacker gains ability to execute arbitrary code with browser process privileges
3
Lateral reach — past segmentation narrative 3
Attacker
Escalate from browser sandbox to system-level access or exfiltrate sensitive user data
Business
Personal data, credentials, and device integrity compromised across affected iOS installations
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.
