Apple Multiple Products vulnerability
Use-after-free vulnerability in WebKit affecting Apple iOS, iPadOS, macOS, and Safari. Processing maliciously crafted web content enables remote code execution.
Verdict
Today item — known-exploited.
A use-after-free flaw in WebKit allows attackers to achieve code execution through malicious web content. The vulnerability affects multiple Apple platforms and any third-party products relying on WebKit for HTML processing.
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
11 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 2023-04-10).
Probability (EPSS)
EPSS 0.27076 — 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-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
I craft malicious web content designed to trigger a use-after-free condition in WebKit's memory management.
Business
Users visiting compromised or attacker-controlled websites face immediate risk of device compromise and data theft.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I deliver the malicious content via web browsing, email links, or embedded frames to reach Safari or WebKit-dependent applications.
Business
Attack surface expands across all Apple platforms and third-party applications using WebKit, multiplying exposure.
3
Lateral reach — past segmentation narrative 3
Attacker
I exploit the use-after-free to execute arbitrary code with the privileges of the affected application or browser process.
Business
Attackers gain unauthorized access to user data, system resources, and can establish persistent footholds on 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.
