Mozilla Firefox vulnerability
Mozilla Firefox fails to properly initialize data structures in SVG zoom event handlers, allowing remote attackers to read sensitive information from process memory via crafted websites.
Verdict
Today item — known-exploited.
A remote attacker can craft a malicious website that exploits uninitialized memory in Firefox's SVG zoom event handling to leak sensitive data from the browser process. This information disclosure vulnerability requires user interaction but poses a real risk to confidentiality.

1 independent public report 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 2022-03-03).

Severity / affected
CVSS 6.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N) · Affected: Mozilla, Firefox. 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-119 Memory Buffer Bounds Error — weakness family: Memory safety.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 3213 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 a malicious website containing SVG content that triggers zoom events with uninitialized data structures.
Business
User confidentiality is compromised as sensitive process memory contents may be exposed to the attacker.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I host the exploit on a website and wait for Firefox users to visit it, or distribute it through social engineering.
Business
Widespread exposure of user data and browser process memory across the Firefox user base creates privacy and compliance risks.
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.
