Apple Multiple Products vulnerability
A type confusion vulnerability in multiple Apple products allows arbitrary code execution through maliciously crafted web content.
Verdict
Today item — known-exploited.
This type confusion issue enables remote code execution via web-based attack vectors. The vulnerability has been exploited in the wild, indicating active threat activity against Apple product users.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
2 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 2022-05-04).
Probability (EPSS)
EPSS 0.18172 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Apple, Multiple Products. 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
I craft malicious web content that exploits type confusion in the target application's memory handling.
Business
Users face direct risk of compromise when visiting untrusted or compromised websites.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I trigger the type confusion by processing my malicious content, causing the application to misinterpret object types.
Business
Apple's web-facing products become vectors for unauthorized access to user systems and data.
3
Lateral reach — past segmentation narrative 3
Attacker
I achieve arbitrary code execution within the application's security context.
Business
Attackers gain ability to steal credentials, install malware, or pivot to other systems on the network.
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.
