Apple Multiple Products vulnerability
Apple products contain a cross-site scripting vulnerability in web content processing that may enable attackers to inject malicious scripts. The vulnerability is actively exploited in the wild.
Verdict
Today item — known-exploited.
Cross-site scripting vulnerability in Apple iOS, macOS, and related products allows attackers to inject malicious scripts through crafted web content. Active exploitation in the wild indicates immediate risk to users accessing untrusted web sources.

Is it exploitable?
— the evidence, ranked above the scoreReported 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 2024-11-21).
Probability (EPSS)
EPSS 0.22728 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 6.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L) · Affected: Apple, Multiple Products. Confirm exact fixed builds in the vendor advisory.CVSS — CISA-assigned via the ADP container (CVE.org), version 3.1; the CNA left no metrics, so CISA's own score is used ahead of NVD.
Weakness (CWE)
Mapped to CWE-79 Cross-site Scripting (XSS) — weakness family: Web / client.CWE assignment from the public NVD record (may be stale); the weakness class drives how the flaw is exploited.
CISA SSVC (triage disposition)
Exploitation: active · Automatable: no · Technical Impact: partialCISA's own stakeholder-specific triage inputs, published in the CVE record (CISA Coordinator role). NOTE: this is CISA's three decision points; the final Act/Attend/Track decision also requires a Mission & Well-being input not published here, so no overall decision is asserted.
Currency of the record
CISA added this to its KEV catalog 2 days after the CVE record was published.KEV lag = CISA-KEV dateAdded − CVE.org datePublished; a floor on how long the known-exploited flaw sat in the public record before the federal catalog listed it. Severity/weakness here is CNA- or CISA-assigned (current at disclosure), independent of NVD's analysis backlog.

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 containing JavaScript payloads targeting the vulnerable web processing engine.
Business
User devices become vectors for credential theft, session hijacking, and unauthorized data exfiltration from trusted web applications.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I distribute the malicious content through compromised websites, advertisements, or phishing campaigns to reach target users.
Business
Enterprise security posture degrades as employee devices become compromised, increasing insider threat surface and data breach risk.
3
Lateral reach — past segmentation narrative 3
Attacker
I execute arbitrary JavaScript in the victim's browser context to steal cookies, session tokens, or perform actions on their behalf.
Business
Customer trust erodes as personal data and financial information are compromised through trusted Apple device ecosystems.
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.
