Remote Desktop Services Failures on Windows Servers Following September Update

September 2026 Patch Tuesday updates cause Windows Server 2019/2022/2025 RDS sessions to freeze, forcing administrators to roll back.

Cumulative updates KB5122876 (Windows Server 2019), KB5122882 (2022), and KB5122871 (2025) trigger Remote Desktop Services freezes hours after boot, with RDP connections hanging at 'Connecting…' and Event ID 20498 logged. Administrators trace the fault to an apparent deadlock in RDPSERVERBASE!WDLIB_Close during session teardown; only hard resets restore service and the issue recurs. The same September release patched roughly 973 vulnerabilities, including two actively exploited zero-days (CVE-2026-81963, CVE-2026-85880, both in CISA's KEV) and a critical RDS RCE, CVE-2026-69525 (CVSS 9.8). Workarounds include DISM-based removal of the update or an unofficial FeatureManagement registry key disabling the suspected audio-redirection code path; Microsoft has not yet confirmed the bug.

GitLab’s critical flaw is already drawing internet-wide probes

GitLab patches two critical flaws (CVE-2026-85706 CVSS 10.0, CVE-2026-87719) as WatchTowr observes internet-wide probing of the unauthenticated file-read bug.

GitLab released emergency patches for two high-severity flaws in Community and Enterprise Editions, urging self-managed operators to upgrade immediately while saying its hosted and Dedicated offerings are fixed or unaffected. CVE-2026-85706 (CVSS 10.0) is a path traversal in the repository commits interface that lets unauthenticated attackers read any file on the server and affects releases 18.7 through 19.1.8 plus the 19.2 and 19.3 lines before patching. CVE-2026-87719 (CVSS 9.9, Enterprise Edition only) lets a logged-in Duo Chat user hide a command in a request that triggers Advanced Search settings and password disclosure. WatchTowr Labs reported it is already watching probes that can trigger the path traversal flaw in a single HTTP request, though CISA had not added either issue to the KEV list as of Friday afternoon.

Cisco Secure Email Gateway SQL Injection Vulnerability

Unauthenticated SQL injection in Cisco Secure Email Gateway email parsing enables root command execution via crafted messages; patches released.

A vulnerability in email parsing of Cisco AsyncOS for Cisco Secure Email Gateway allows an unauthenticated, remote attacker to execute arbitrary commands with root privileges on the underlying operating system. Insufficient validation in the email parsing logic lets a crafted email containing malicious SQL statements achieve arbitrary SQL execution and root command execution. Cisco has released software updates, and the companion September 2026 hardening advisory states this flaw is actively exploited.

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.

Nearly 1 in 10 Exposed LiteLLM Gateways Accepted the Example "sk-1234" Admin Key

Wiz found 294 of 3,074 internet-facing LiteLLM gateways accepted the documented default admin key sk-1234, exposing provider API keys and cloud IAM credentials.

Wiz Research's February Shodan scan found 3,074 LiteLLM gateways, 294 of which accepted the setup guide's sk-1234 admin key; 191 had no master key set and would accept any credential. The master key doubles as the authentication switch, and before 1.82.0-stable a gateway started without one granted every request full admin rights, exposing stored provider API keys, prompts, and MCP-connected tools. A documented pass-through endpoint lacks checks against private and cloud metadata addresses, letting an admin-key holder retrieve cloud IAM credentials, though no real-world abuse is reported. Related LiteLLM flaws include CVE-2026-59821 (disputed guardrail code execution), CVE-2026-59822 (CVSS 8.8, added to CISA KEV on September 2 and observed against Wiz honeypots), and CVE-2026-42271, used to install a cryptominer.

Alby Hub Critical Flaw Could Let Attackers Take Over Internet-Exposed Bitcoin Wallets

Alby warns a critical flaw in internet-exposed Alby Hub Bitcoin wallets (v1.7.0–v1.18.5) could allow takeover and fund theft; update to v1.24.0.

Alby disclosed a critical flaw in Alby Hub, its self-hosted Lightning wallet, affecting versions v1.7.0 through v1.18.5 when the management interface is reachable from the internet. The flaw could let attackers take over a wallet and send its funds; one affected user has been reported so far, with no word on losses. Versions v1.19.0 and later contain the fix, and Alby advises updating to v1.24.0, binding port 8080 to localhost or firewalled sources, and changing unlock passwords on previously exposed hubs. Full technical details will be published later under responsible disclosure.

Microsoft’s Biggest Patch Tuesday: 974 CVEs, 2 Zero-Days and 20 Wormable Bugs

Microsoft's record September 2026 Patch Tuesday fixes 974 CVEs, including two exploited Windows privilege-escalation zero-days and 20 wormable bugs.

Microsoft's September 2026 Patch Tuesday fixes a record 974 CVEs, including two actively exploited zero-days: CVE-2026-85880, an ALPC heap buffer overflow, and CVE-2026-81963 in the Windows Update Stack, both CVSS 7.8 local privilege escalations. It also addresses an unauthenticated Exchange RCE (CVE-2026-55007) triggered by Visio attachment content indexing under memory pressure, an RDP use-after-free (CVE-2026-69525, CVSS 9.8), and 20 wormable flaws in DNS, DHCP, SMB, Active Directory, and other components. ZDI attributed the rising volume partly to AI-assisted vulnerability discovery, noting no corresponding spike in active exploits yet.
