Apple iOS and macOS vulnerability
Apple iOS and macOS contain an out-of-bounds write vulnerability in web content processing that enables remote code execution. The flaw has been exploited in the wild.
Verdict
Today item — known-exploited.
An unauthenticated attacker can achieve arbitrary code execution on affected Apple devices by delivering malicious web content, potentially compromising device integrity and user data without user interaction beyond visiting a compromised or attacker-controlled website.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
9 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 2022-08-18).
Probability (EPSS)
EPSS 0.09785 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Apple, iOS and macOS. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-20 Improper Input Validation, CWE-787 Out-of-bounds Write — 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 designed to trigger an out-of-bounds write in the target's browser or web rendering engine.
Business
User devices become vulnerable to compromise through routine web browsing, expanding attack surface beyond traditional application vectors.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I deliver this content via compromised websites, watering hole attacks, or advertising networks to reach target devices.
Business
Enterprise security perimeters fail to prevent compromise since the attack occurs within legitimate web browsing activity.
3
Lateral reach — past segmentation narrative 3
Attacker
I exploit the memory corruption to execute arbitrary code with the privileges of the affected process.
Business
Attackers gain persistent access to sensitive data, device functionality, and potential lateral movement within corporate 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.
