NIST and CISA finalize playbook to stop token theft and forgery

NIST and CISA finalized NIST IR 8587, a playbook helping federal agencies and cloud providers defend identity tokens against theft and forgery.

The finalized NIST IR 8587 guidance covers protecting token signing keys, verifying tokens, lifetimes, revocation, session management, and dividing security responsibilities between cloud providers and customers. It cites an incident in which foreign actors forged tokens with a stolen commercial signing key to steal more than 60,000 emails from one government agency. It also recommends extending token protections to AI agents and preparing identity systems for a future post-quantum cryptography transition.

Protecting Tokens and Assertions from Forgery, Theft, and Misuse: Implementation Recommendations for Agencies and Cloud Service Providers

NIST and CISA publish final interagency report with implementation guidance for protecting tokens and assertions from forgery and misuse.

CISA released a final NIST/CISA interagency report guiding federal agencies and cloud service providers on protecting identity assertions, access tokens, and cryptographic mechanisms underlying modern authentication and authorization. It addresses forgery, theft, and misuse of signed tokens that adversaries use for lateral movement and data access in hybrid and multi-cloud, SSO, federation, and API-based environments. The final version updates token validation, secrets management, and detection-at-scale guidance gathered via the Joint Cyber Defense Collaborative, and supports Executive Order 14306 and Secure by Design principles.

Cisco Packaged Contact Center Enterprise and Cisco Unified Contact Center Enterprise Server-Side Request Forgery Vulnerability

Cisco patched an authenticated SSRF flaw in Packaged CCE and Unified CCE that lets credentialed users send arbitrary network requests from affected devices.

A server-side request forgery vulnerability caused by improper input validation of specific HTTP requests affects Cisco Packaged Contact Center Enterprise and Cisco Unified Contact Center Enterprise. An authenticated, remote attacker with valid user credentials can send crafted HTTP requests to make the device issue arbitrary network requests. Cisco has released software updates; no exploitation is reported in the advisory.

CISA and NIST Issue Guidance to Protect Cloud Identity Tokens

CISA and NIST published Interagency Report 8587 with voluntary guidance to harden cloud identity tokens against theft, forgery, and lateral movement.

CISA and NIST released NIST Interagency Report 8587 on September 15 with final voluntary guidance for federal agencies, cloud providers, and their customers on protecting SSO, federation, and API tokens. Requirements include one-hour maximum token lifetimes, 90-day signing key rotation for high-impact systems, hardware-backed key storage, explicit audience fields, and keeping tokens out of logs. The guidance was motivated by the 2020 ADFS compromise where forged SAML assertions bypassed MFA, and an incident where a leaked consumer signing key enabled token forgery and theft of 60,000+ emails from one agency. Nearly 250 public comments shaped the text, with input from Google, Microsoft, Okta, AWS, Oracle, IBM, HashiCorp, Wiz, and the OpenID Foundation via the Joint Cyber Defense Collaborative.

Tycon Systems TPDIN-Monitor-WEB3

CISA reports three flaws (hard-coded credentials, CSRF, missing authorization) in Tycon TPDIN-Monitor-WEB3 <=2.2.9 enabling MitM, credential theft, or device resets.

CISA published ICSA-26-246-08 for Tycon Systems TPDIN-Monitor-WEB3 versions 2.2.9 and prior, covering CVE-2026-77847 (use of hard-coded credentials, CWE-798), CVE-2026-82712 (CSRF, CWE-352), and CVE-2026-82684 (missing authorization, CWE-862). Exploitation could enable man-in-the-middle attacks, factory resets, credential wiping, or extraction of system credentials, configurations, and flash contents; the CSRF issue scores CVSS 8.8. No public exploitation has been reported; CISA recommends isolating devices from business networks.

CISA and NIST Release Technical Checklist for Safeguarding Identity Tokens From Theft and Misuse

CISA and NIST published NIST IR 8587, final guidance for protecting identity tokens from forgery, theft, replay, and signing-key compromise.

NIST Interagency Report 8587 (September 15, 2026) expands the IA-13 'Identity Providers and Authorization Servers' control from NIST SP 800-53 R5.1.1, guiding federal agencies and cloud providers on SSO, identity federation, and machine-to-machine authentication. It requires hardware-backed signing-key storage for moderate-impact systems, 90-day key rotation for high-impact systems, token lifetimes under one hour, and sender-constrained mechanisms such as mutual TLS and DPoP. The report cites incidents including forged SAML assertions that exposed over 60,000 emails from a federal agency. It also extends guidance to agentic AI systems using signed tokens and urges post-quantum cryptography migration planning.

ST Engineering iDirect iQ-Series Terminals (Update A)

CISA advisory details four flaws in ST Engineering iDirect iQ-Series VSAT terminals <=4.5.2.1, enabling device data theft, CSRF-driven reboots, and local privilege escalation.

CISA's Update A to ICSA-26-183-01 covers ST Engineering iDirect iQ-Series, 3315-Series and 9-Series terminals at firmware <=4.5.2.1, deployed across communications, defense, energy and transportation. CVE-2026-38059 exposes unauthenticated /api/identity and /api/ endpoints leaking serial number, DID, TPK, MAC address and firmware version, potentially enabling terminal impersonation; CVE-2026-38057 is a CSRF flaw letting an attacker force terminal reboots and satellite link loss via /api/reboot. CVE-2026-38056 enables local privilege escalation using the factory-configured technician account (CVSS 3.1 8.8, CVSS 4.0 9.4), and CVE-2026-38058 exposes crackable MD5-crypt root password hashes. All four flaws were reported to CISA by Ahmed Alqahtani of Aramco.

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.
