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 0.82045 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Microsoft, Internet Explorer. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-399 Resource Management Errors — weakness family: Resource / availability.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 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.
