AI agent authorization risks remain a gap in new NIST-CISA token security guidance
NIST and CISA release IR 8587 guidance on securing signed tokens, but AI agent authorization and delegation risks remain out of scope.
NIST, with CISA support, published 'Protecting Tokens and Assertions from Forgery, Theft, and Misuse' (NIST IR 8587), recommending continuous monitoring and tighter token lifecycle controls for SSO and API access. The guidance does not yet fully address AI agent identity, delegation chains, or prompt injection steering agents with valid tokens, and NIST says new or expanded standards are needed. Experts recommend treating AI agents as low-trust non-human identities, maintaining agent inventories, expiring credentials after task completion, and requiring human approval for high-risk actions. The report references shared-signal mechanisms like CAEP and RISC, and follows a May incident where a CISA contractor GitHub repository exposed AWS and GitHub tokens.

Siemens Mendix SAML
Siemens Mendix SAML module fails signature validation, allowing unauthenticated account hijacking in specific SSO configurations (CVE-2026-80465).
CISA republished Siemens advisory SSA-887643 for CVE-2026-80465 (CVSS 8.7) in the Mendix SAML module, affecting Mendix 10/11-compatible versions before 4.2.3 and Mendix 9.24-compatible versions before 3.6.27. The module improperly validates SAML response signatures (CWE-347), letting unauthenticated remote attackers hijack an account in specific SSO configurations. Mendix has released fixed versions and recommends updating.

CISA Red Team Fully Compromised Two Critical Infrastructure Orgs
CISA red teams achieved full domain and cloud compromise at two critical infrastructure orgs; one SOC never detected the intrusion.
CISA advisory AA26-237A documents two simultaneous red team assessments. Organization A (Government Services sector) missed the intrusion entirely, as default credentials on a web app, ADCS ESC1 abuse, and thousands of false-positive alerts let the red team reach sensitive business systems and read SOC email. Organization B (Water/Wastewater sector) detected, isolated, and reimaged hosts quickly, but both orgs lacked Conditional Access for workload identities, and B still exposed DCSync, Golden Ticket, and OT network attack paths.

CISA Red Team Compromised Two Critical Infrastructure Orgs, One Detected Nothing
CISA red teams fully compromised two critical infrastructure orgs with similar tradecraft; one detected nothing, the other contained phishing within minutes.
CISA advisory AA26-237A, 'A Tale of Two SOCs,' describes two simultaneous red team assessments of a Government Services organization and a Water and Wastewater Systems organization, both compromised to the domain level. Organization A never detected the intrusion, enabled by default credentials, a misconfigured AD CS template (ESC1), cleartext credentials, non-expiring static AWS keys, and over-permissioned Entra ID applications. Organization B detected and isolated phishing within 2-20 minutes, though the red team still reached krbtgt via DCSync from cleartext SCCM credentials. CISA attributes the outcome gap to people and processes rather than the security tools themselves.

Water sector passes, government sector fails attempts to spot and halt simulated CISA attack
CISA red teamers compromised both a government and a water organization; water defenders detected and contained the simulated attack, government defenders did not.
CISA's red team gained initial access, elevated domain privileges, and lateral movement into sensitive business systems and cloud resources at an unnamed government organization, whose SOC ignored low- and medium-severity EDR alerts buried under thousands of false positives. A water organization's SOC quarantined phishing-compromised workstations within 2, 10, and 20 minutes, and later detected and isolated intrusions reaching the OT DMZ bastion host. Both organizations underestimated cloud risk, lacked Microsoft Conditional Access for workload identities, and had no process to revoke compromised access and refresh tokens. This is one of CISA's rare public red-team reports since 2023.

Slovakia Warns of Cyber Risks in Road Speed Cameras
Slovakia's NBÚ warns that speed camera systems from SODASUS, Simicon and NEROline pose cyber risks including undocumented remote access.
Slovakia's National Security Authority (NBÚ) warned of a significant cyber threat tied to several road speed camera products: NERO R-ONE units sold by Cyprus-based SODASUS, and Cordon-series cameras made by Russia's Simicon and sold by Croatia's NEROline. A security analysis requested by the Interior Ministry found weak protections, mismatches between documented and actual communication settings and software versions, unclear hardware/software provenance, and pre-configured remote-access mechanisms outside operator control. NBÚ warned that compromised cameras could expose vehicle and licence-plate data, tamper with records, or serve as a foothold into public-sector networks lacking segmentation. The Interior Ministry reportedly removed the units from its pilot deployment and asked the supplier to replace them with equipment meeting Slovak and EU security requirements.
