pgAdmin 4 versions 6.2-9.17 contain critical auth bypass CVE-2026-86863 (CVSS 9.8) letting unauthenticated attackers impersonate administrators; fixed in 9.18.

A critical authentication bypass (CVE-2026-86863, CVSS 3.1 score 9.8) affects pgAdmin 4 versions 6.2 through 9.17 when Webserver authentication is enabled in AUTHENTICATION_SOURCES. The WebserverAuthentication.get_user() function falls back to client-controlled HTTP headers such as X-Forwarded-User when the WEBSERVER_REMOTE_USER environment variable is absent, allowing unauthenticated remote attackers to log in as any user, including administrators, without a password or MFA. Successful attackers could view, alter, or delete PostgreSQL database objects and data accessible through the hijacked privileged session. Version 9.18 fixes the issue by trusting only genuine CGI/WSGI environment variables by default and requiring explicit options like WEBSERVER_REMOTE_USER_FROM_HEADER with trusted proxies for header-based identity.

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.

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.

Hackers Impersonate ChatGPT Subscription Alerts to Steal OpenAI Account Credentials

Cofense reports a phishing campaign using fake ChatGPT subscription payment notices to lure users to credential-harvesting pages and steal OpenAI account logins.

Cofense identified phishing emails impersonating ChatGPT subscription invoices, using the genuine logo, 'Subscription Payment Required' wording, and a 48-hour urgency deadline. Links route through a Google notifications API redirect wrapper to attacker-controlled nxcli[.]io infrastructure hosting a fake ChatGPT login page that forwards submitted credentials to the attackers before showing an error. Cofense published IOCs including sender support@9527db6e1a[.]nxcli[.]io and two stage-2 payload URLs; the operators behind the campaign were not named.

Iranian Hackers Use Fake MRI Results to Infect Victims With CHOSEN BRICK Spyware

Iranian state-linked hackers deliver CHOSEN BRICK Windows spyware via fake MRI results to surveil dissidents, activists, and journalists in the UK, US, and Netherlands.

A joint advisory from the UK NCSC, FBI, and the Netherlands' AIVD links Iranian state-linked actors to CHOSEN BRICK, a Windows spyware family used for long-term surveillance since at least 2025. Targets are approached on WhatsApp or Telegram with tailored lures such as fake MRI scan results or application files, and operators often redirect victims to personal devices to bypass corporate controls. The malware persists via Run registry keys, adds antivirus exclusions, uses a per-victim Telegram bot for command and control, and exfiltrates data through cloud storage and proxy services. Capabilities include screenshots, audio recording, email and messaging theft, command execution, file deletion, data wiping, and some victims' details have appeared on pro-Iranian leak sites for harassment.

Steam Windows 0-Day Vulnerability Allows Users to Silently Escalate to Full SYSTEM Privileges

A public BrokenPipe PoC exploits a signature-coverage flaw in Steam's Windows service, letting unprivileged local users gain NT AUTHORITY\SYSTEM without a patch or CVE.

Researcher KillaBoi published the BrokenPipe PowerShell proof of concept on September 14, 2026, targeting steamservice.exe, Steam's privileged Windows client service. The flaw is a signature-coverage gap: the service accepts a caller-controlled installation root alongside a genuine Valve-signed install-script VDF, causing the SYSTEM-level service to execute a relocated attacker-chosen launcher. Testing reportedly succeeded on Steam 10.96.30.42 on recent 64-bit Windows 10 and Windows 11 builds, returning whoami output of NT AUTHORITY\SYSTEM (S-1-5-18). Valve was reportedly aware since March 2026, the HackerOne submission was marked duplicate, and no CVE, advisory, or fix exists at publication time.

New Chinese-Made ‘RatHat’ Android Malware Leverages AI to Steal Financial Data

Zimperium details RatHat, a new Android banking trojan using a generative AI engine to automate credential and OTP theft.

Zimperium's zLabs identified RatHat, an Android malware delivered as fake APKs via malvertising, smishing and third-party forums, and published its analysis on September 16. Its three-part architecture combines a malicious app, a Go agent (liblocal-service.so) running privileged commands through the ADB shell, and an FRP client (libmedia_codec.so) maintaining a reverse tunnel to the C2. The app harvests banking credentials, notifications, 2FA codes and OTPs and captures screens and inputs, while a dropper abuses SessionInstaller APIs to bypass Android's restricted settings behind four anti-analysis and one anti-debug layers. Notably, RatHat serializes the Accessibility tree to XML and queries a generative AI assistant, likely Google's Gemini, in Mandarin to resolve click coordinates and navigation commands.

CISA Urges Organizations to Deploy Cyber Decoys to Detect Hackers Inside Networks

CISA's new guidance urges organizations to deploy cyber decoys like honeytokens and tripwires to detect attackers using valid credentials and living-off-the-land techniques.

CISA published 'Using Cyber Decoys to Strengthen Detection and Response' on September 16, 2026, advising decoy assets that appear legitimate but generate high-confidence alerts when accessed. It describes tripwires, breadcrumbs, and honeytokens such as fake usernames, passwords, API keys, and cloud access tokens, and recommends starting with low-complexity deployments like nonfunctional Active Directory accounts, decoy file shares, and isolated mimic hosts. The agency warns decoys must be segmented and nonfunctional to prevent attackers pivoting to real systems, and aligns decoy planning with MITRE Engage and ATT&CK.
