Microsoft Internet Explorer vulnerability
Microsoft Internet Explorer use-after-free vulnerability allowing remote code execution through invalid pointer access after object deletion.
Verdict
Today item — known-exploited.
Remote attackers can execute arbitrary code by exploiting a use-after-free condition in Internet Explorer. The vulnerability is actively exploited in the wild with high exploit probability. Affected versions are end-of-life.

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 2026-05-20).
Probability (EPSS)
EPSS 0.82172 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 8.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) · Affected: Microsoft, Internet Explorer. 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-399 Resource Management Errors — weakness family: Resource / availability.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: totalCISA'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 5915 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.
Public exploit available
Public exploit tooling is catalogued for this CVE (a functional/weaponized public exploit). Catalog entries: Metasploit module. We link the catalog page(s) only — no payload or code is hosted or restated here.Link, never host — the catalog page is the source; basicsecurity.net does not redistribute payloads.

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 webpage or email containing specially crafted HTML/JavaScript that triggers object deletion and subsequent invalid pointer access in Internet Explorer.
Business
Users visiting untrusted websites or opening malicious email content face arbitrary code execution on their systems, leading to data theft, malware installation, and system compromise.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I deliver the exploit through drive-by download attacks or watering hole compromises targeting Internet Explorer users.
Business
Organizations face widespread endpoint compromise, credential theft, and lateral movement within networks due to active exploitation in the wild.
3
Lateral reach — past segmentation narrative 3
Attacker
I establish persistent access and escalate privileges on compromised systems to move laterally through the network.
Business
Enterprise security posture degrades as attackers gain foothold for data exfiltration, intellectual property theft, and further infrastructure compromise.
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.
