UPDATE: Ivanti EPMM CVE-2026-5787 / CVE-2026-6973 — KEV deadline TOMORROW (2026-05-10); EU victim organisations named; 508 internet-exposed EU instances

UPDATE (originally covered 2026-05-08):

The CISA KEV deadline for CVE-2026-6973 (Ivanti EPMM admin API RCE, CVSS 7.2) is tomorrow, 2026-05-10. Organisations that have not yet isolated or patched on-premises Ivanti EPMM instances are in immediate compliance breach. CERT-FR CERTFR-2026-AVI-0552 and BSI advisory from 2026-05-07 both require organisations to treat the CVE-2026-5787 → CVE-2026-6973 chain as a single critical exposure requiring immediate action, with 508 EU on-premises instances identified as internet-accessible by NCSC-NL scanning as of 2026-05-07.

Named victims confirmed in public statements or EU supervisory authority filings during the 36-hour window: European Commission (DG DIGIT notified, isolated affected infrastructure); Dutch Data Protection Authority (Autoriteit Persoonsgegevens) (confirmed EPMM instance impacted in the 2026-05-03–07 exploitation wave, investigation ongoing); Netherlands Council for the Judiciary (Raad voor de rechtspraak) (EPMM administrative console was internet-accessible until 2026-05-05; extent of access under assessment); Finnish Valtori (Government ICT Centre, confirmed EPMM compromise affecting shared government IT services, NCSC-FI advisory published). All named organisations used EPMM in MDM capacity, meaning the exposed admin APIs had device management access to enrolled endpoints including mobile devices of employees with elevated privilege.

Credential-chaining risk: Ivanti disclosed a separate cluster of EPMM vulnerabilities in January 2026 (CVE-2026-1281 and CVE-2026-1340, tracked separately) in which admin-account credentials were extracted from compromised instances. Organisations that patched CVE-2026-1281/1340 at the time but did not rotate admin credentials remain at elevated risk that the May 2026 exploitation wave leveraged pre-extracted credential sets to accelerate authentication bypass to direct post-auth RCE.
