Oracle WebLogic Server vulnerability

Oracle WebLogic Server contains an unspecified vulnerability allowing unauthenticated network attackers to access critical data via T3 or IIOP protocols.

Verdict

Today item — known-exploited.

An unauthenticated remote attacker can exploit this vulnerability through T3 or IIOP network protocols to gain unauthorized access to sensitive data within Oracle WebLogic Server, potentially compromising all accessible information.

Is it exploitable?

— the evidence, ranked above the score
Exploit available
Fully weaponized — public exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported exploitation
4 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 2026-06-01).
CISA KEV ↗Confirmed
Probability (EPSS)
EPSS 0.4997 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) · Affected: Oracle, WebLogic Server. Confirm exact fixed builds in the vendor advisory.CVSS — CNA-assigned (CVE.org), version 3.1, set at disclosure.
CVE.org ↗Reported
CISA SSVC (triage disposition)
Exploitation: active · Automatable: yes · 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.
CISA-ADP ↗Reported
Currency of the record
CISA added this to its KEV catalog 685 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 urgency
Attribution 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 board
1

Front door — unauthenticated access narrative 1

Attacker
I identify that Oracle WebLogic Server is exposed on the network and accepts T3 or IIOP protocol connections without authentication.
Business
The organization's WebLogic infrastructure is discoverable and accessible to external threat actors without credential requirements.
2

Keys to the kingdom — privilege/identity takeover narrative 2

Attacker
I send a crafted request via T3 or IIOP to trigger the unspecified vulnerability in the WebLogic Server.
Business
The vulnerability allows bypass of authentication controls, enabling direct exploitation without valid credentials.
3

Lateral reach — past segmentation narrative 3

Attacker
I gain unauthorized access to critical data and sensitive information stored within or accessible through the WebLogic Server.
Business
Confidential business data, customer information, and system credentials are exposed to unauthorized disclosure and potential misuse.

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.
