Apple Multiple Products vulnerability
Apple WebKit contains an out-of-bounds write vulnerability allowing malicious web content to escape the Web Content sandbox across iOS, iPadOS, macOS, and other products.
Verdict
Today item — known-exploited.
This memory corruption flaw in WebKit's HTML parsing enables attackers to bypass sandbox isolation through crafted web content, potentially achieving code execution with elevated privileges on affected Apple devices and third-party applications using WebKit.
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
10 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 2025-03-13).
Probability (EPSS)
EPSS 0.0424 — 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-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 HTML content designed to trigger an out-of-bounds write in WebKit's parser.
Business
Attackers gain ability to execute arbitrary code outside the Web Content sandbox, compromising device security.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I host the malicious content on a website or distribute it through messaging platforms to reach target users.
Business
Attack surface expands across web browsing, email clients, and messaging apps that embed WebKit rendering.
3
Lateral reach — past segmentation narrative 3
Attacker
I exploit the sandbox escape to access sensitive user data, install malware, or establish persistent device compromise.
Business
User privacy and device integrity are compromised; third-party applications relying on WebKit face inherited vulnerability exposure.
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.
