New Passkey Attacks Can Recover Synced Private Keys or Bypass Phishing
Three research teams showed passkey bypasses: WebAuthn assertion replay in Microsoft Entra ID, synced-passkey key recovery in Google Password Manager, and Windows Hello key reuse.
SpecterOps' Pass-the-Passkey research showed Windows stored past YubiKey signatures in cleartext and chained this with Microsoft Entra ID passkey validation weaknesses to impersonate privileged users despite phishing-resistant MFA; the Windows Event Logging Service issue is tracked as CVE-2026-34348 (CVSS 6.5) and fixed in July 2026 updates. Unit 42's Golden Pass-ta-key attack recovered the 32-byte Security Domain Secret protecting Google Password Manager synced passkeys from Chrome on Windows via pre-existing malware. Dirk-jan Mollema showed in-session malware can use a hardware-bound Windows Hello for Business key without a fresh PIN or biometric check. Microsoft applied Entra-side mitigations for the relay assertion issue; no real-world exploitation has been reported.
AL26-020 - Vulnerabilities Impacting MikroTik RouterOS - CVE-2026-67276, CVE-2026-67277 and CVE-2026-86060
Canada's Cyber Centre warns of three exploited MikroTik RouterOS vulnerabilities affecting SSH-exposed devices; CISA added two to its KEV catalog.
The Canadian Centre for Cyber Security issued alert AL26-020 for three MikroTik RouterOS vulnerabilities, especially on devices exposing SSH to the internet: CVE-2026-67277 (missing authentication, CWE-306, enabling sensitive information disclosure), CVE-2026-86060 (argument injection, CWE-88, enabling privilege escalation), and CVE-2026-67276 (improper cryptographic signature verification, CWE-347, allowing SSH command channel access without the private key). On September 10, 2026, CISA added CVE-2026-67277 and CVE-2026-86060 to its Known Exploited Vulnerabilities catalog. Fixed versions include RouterOS 6.49.21, 7.23.4 (Long-Term), 7.24.2 (Stable), and 7.25 beta 3.
Amasty patches dozens of Magento extensions, 2 critical
Amasty patched dozens of Magento/Adobe Commerce extensions, including two critical flaws allowing unauthenticated web shell upload and remote code execution.
Extension vendor Amasty released fixes for a large batch of Magento and Adobe Commerce modules, with critical unauthenticated file upload flaws in Advanced Product Reviews and Gift Card that allow attackers to plant web shells and take full control of stores. Dozens of additional high-, medium- and low-severity extensions were also patched. The vendor says the release affects almost every Magento and Adobe Commerce store. A related Order Attributes flaw was previously exploited heavily, with Sansec Shield blocking over 12,000 attempts against 25% of Magento stores in three days.
Microsoft Patch Tuesday, September 2026 Security Update Review

Microsoft's September 2026 Patch Tuesday fixes 974 vulnerabilities, its largest release ever, including 113 critical and 860 important, covering Windows HTTP.sys, Hyper-V, Entra ID, Exchange Server, Office, DNS, and more. Two zero-days are confirmed exploited in the wild: CVE-2026-81963 (Windows Update Stack EoP) and CVE-2026-85880 (ALPC heap overflow), both letting authenticated attackers gain SYSTEM privileges. Notable criticals include an Entra ID authentication bypass (CVE-2026-62916) and multiple Windows DNS Server and Office remote code execution flaws.
Dell Secure Connect Gateway Vulnerabilities Allow Hackers to Gain Unauthorized Access
Dell patches three critical flaws (CVSS up to 9.8) in Secure Connect Gateway 5.0 enabling admin token replay, unauthenticated RCE, and root escalation.
Dell disclosed three critical vulnerabilities in Secure Connect Gateway 5.0 appliance and application deployments. CVE-2026-80172 (CVSS 9.8) lets unauthenticated attackers replay captured requests, which lack nonce validation and time limits, to repeatedly mint administrator access and refresh tokens. CVE-2026-61410 (9.4) is a missing-authorization flaw enabling unauthenticated remote command execution, and CVE-2026-80238 (9.3) is an exposed Docker socket allowing local privilege escalation to root and container escape. Fixes ship in appliance 5.36.00.16 and application 5.36.00.00.
