Published severityHighOperational priority:Critical, raised one band.upgradedsince 30 Oct 2026

Evidence used

  • CISA confirms exploitation in the wild.
  • Exploitation requires an existing local or physical foothold with privileges.
  • EPSS is 0.53% for the current model date.

Compensating controls

  • Restrict local access and enforce least privilege on affected hosts.
  • Increase monitoring for the attack path and post-exploitation behaviour described in the report.

Verification

  1. Confirm that the asset runs Ivanti Connect Secure and falls inside the recorded affected range.
  2. Recheck the vendor advisory before scheduling a change because no verified fixed version is currently retained.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 3 daysRemediation target: Within 90 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

01

What, why and how

Ivanti Connect Secure contains a missing authentication for critical function vulnerability that could allow a local authenticated attacker to escalate their privileges. This vulnerability can be chained with CVE-2026-104935 and CVE-2026-118527.

What

Ivanti Connect Secure contains a missing authentication for critical function vulnerability that could allow a local authenticated attacker to escalate their privileges. This vulnerability can be chained with CVE-2026-104935 and CVE-2026-118527.

Why

The product imports, requires, or includes executable functionality (such as a library) from a source that is outside of the intended control sphere.

How

An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
Confirmed in the wild

CISA added this CVE to its Known Exploited Vulnerabilities catalogue on 2026-10-30.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
local access → Inclusion of Functionality from Untrusted Control Sphere → cause the confidentiality, integrity or availability impact described by the vendor

CWE-829 ↗

CWE-829: Inclusion of Functionality from Untrusted Control Sphere. The product imports, requires, or includes executable functionality (such as a library) from a source that is outside of the intended control sphere.

NCSC-NL · Dutch · NCSC-2026-0416ZeroDay kwetsbaarheden verholpen in Ivanti Connect Secure

Een kwaadwillende kan de kwetsbaarheid (CVE-2026-104935 ) misbruiken om zonder voorafgaande authenticatie willekeurige commando's uit te voeren op het kwetsbare systeem. Ivanti meldt op de hoogte te zijn van rapporten dat de kwetsbaarheid als ZeroDay kwetsbaarheid is misbruikt. Er is (nog) geen publieke Proof-of-Concept (PoC) beschikbaar, maar het NCSC verwacht dat publieke PoC of exploitcode op korte termijn beschikbaar komt, wat de kans op grootschalig misbruik vergroot. **Update: **Ivanti heeft twee nieuwe kwetsbaarheden gepubliceerd (CVE-2026-111357 en CVE-2026-118527), die samen met CVE-2026-104935 actief zijn misbruikt. Naast de toevoeging van deze twee kwetsbaarheden is ook de lijst met kwetsbare versies uitgebreid. Zo is versie 25.1.1.2, die eerder als gepatcht werd beschouwd voor CVE-2026-104935, nog kwetsbaar voor CVE-2026-111357 en CVE-2026-118527.
