Check Point reported blocking more than 40,000 hits on 7 January 2026 and urged organizations to patch immediately and implement compensating controls.

⚠️ Microsoft has confirmed that the January 13, 2026 cumulative update (KB5073455) can prevent some Windows 11, version 23H2 devices with System Guard Secure Launch enabled from shutting down or entering hibernation, causing them to restart instead. The issue is limited to Enterprise and IoT editions where the update is offered. Microsoft recommends the temporary workaround shutdown /s /t 0 for shutdowns and warns there is currently no hibernation workaround. Users should save work and perform manual shutdowns to avoid battery drain.

🔒 Cisco has released patches for a maximum-severity remote command execution vulnerability (CVE-2025-20393, CVSS 10.0) in AsyncOS that affects Cisco Secure Email Gateway and Secure Email and Web Manager. The defect stems from insufficient validation of HTTP requests in the Spam Quarantine feature and can allow arbitrary commands to run as root when the feature is enabled and reachable from the internet. Cisco says a China-nexus APT tracked as UAT-9686 exploited the bug in the wild, deploying tunneling tools, a log-cleaner and a Python backdoor, and that fixes remove persistence artifacts. Administrators should apply the provided fixed releases and follow the vendor's hardening guidance to restrict access and monitor for anomalous activity.

🔐 Researchers at Varonis Threat Labs uncovered 'Reprompt', a one-click attack that abuses Microsoft Copilot Personal by embedding prompts in URLs and using follow-up server requests to exfiltrate data. It combines a URL 'q' parameter injection, a double-request bypass of initial sanitization, and chained server instructions to siphon conversation history and files without further user interaction. Microsoft issued a patch; organizations should treat prefilled prompts as untrusted and enforce continuous authentication, least privilege, prompt hygiene, auditing, and anomaly detection.

🔒 Palo Alto Networks has released patches for PAN-OS after a researcher disclosed CVE-2026-0227, a high-severity (CVSS 7.7) vulnerability in GlobalProtect gateway and portal components that can trigger a denial-of-service and force affected firewalls into maintenance mode. The vendor reports no known in-the-wild exploitation but acknowledges proof-of-concept code exists. Prisma Access customers have largely been upgraded; on-premises NGFWs must apply vendor updates per the posted remediation table. There are no official workarounds; temporarily disabling the VPN interface may reduce risk while patching.

🔒 Hackers are actively exploiting a maximum-severity authentication bypass in the Modular DS WordPress plugin (CVE-2026-23550) to gain admin-level access on vulnerable installs. The flaw affects versions 2.5.1 and earlier and was first observed in the wild on January 13; the vendor released a fix in version 2.5.2 shortly after disclosure. Site owners should update immediately, review server logs, verify admin accounts, and regenerate WordPress salts after patching.

🔐 The US Cybersecurity and Infrastructure Security Agency (CISA), the UK’s National Cyber Security Centre (NCSC) and the Federal Bureau of Investigation (FBI), alongside international partners, have released principles to secure operational technology (OT) connectivity. Led by NCSC-UK, the guidance offers a shared framework to design and manage secure connectivity across OT environments. It emphasizes embedding cybersecurity into network design to reduce exposure to both state-backed and opportunistic adversaries. The document warns that increased interconnection brings benefits such as real-time analytics and predictive maintenance, but also raises risks that could cause physical harm, environmental damage or service disruption.

⚠️ AVEVA has released patches for multiple vulnerabilities in Process Optimization that could allow remote code execution, SQL injection, privilege escalation, and disclosure of sensitive data. The most severe, CVE-2025-61937, permits unauthenticated remote code execution at OS System privileges (CVSS 10.0). AVEVA's remediation requires updating to Process Optimization v2025; CISA and the vendor also recommend firewall restrictions, ACLs, and ensuring encrypted channels.

⚠️ A critical command injection vulnerability in Fortinet FortiSIEM (phMonitor, tracked as CVE-2025-64155) enables unauthenticated attackers to inject commands and write files that are executed as the root user. Exploit code was disclosed publicly after a responsible disclosure to Fortinet in August 2025, and researchers warn the flaw may have allowed remote root access for nearly three years. Fortinet has released patched builds and advises restricting access to TCP port 7900 and applying updates immediately.

⚠️ Palo Alto Networks patched a high-severity flaw (CVE-2026-0227) in PAN-OS that can allow unauthenticated actors to trigger a denial-of-service, forcing affected firewalls into maintenance mode when GlobalProtect gateway or portal features are enabled. The issue impacts PAN-OS 10.1 and later and some Prisma Access configurations; most cloud Prisma Access instances have been upgraded. Administrators should apply vendor-supplied fixes for their PAN-OS branch immediately to prevent potential disruptions.

⚠️ CISA has added CVE-2025-8110 to its Known Exploited Vulnerabilities catalog after reports of active exploitation targeting Gogs. The high-severity (CVSS 8.7) flaw is a path traversal in the repository file editor's PutContents API that mishandles symbolic links and can lead to remote code execution. There is not yet an official upstream patch, though GitHub pull requests show fixes have been merged and maintainers say new images will include the correction once built. Until patched, users should disable default open-registration, restrict server access behind VPNs or allow-lists, and apply other access controls; FCEB agencies must implement mitigations by Feb 2, 2026.

⚠️ The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has ordered federal agencies to patch a high-severity remote code execution flaw in Gogs tracked as CVE-2025-8110. The issue is a path traversal weakness in the PutContents API that lets authenticated attackers overwrite files outside repositories via symbolic links, enabling arbitrary command execution. Patches released last week add symlink-aware path validation; agencies must remediate by February 2, 2026. Administrators are advised to disable default open registration and restrict server access.

⚠️ CISA added CVE-2025-8110 to its Known Exploited Vulnerabilities (KEV) Catalog for a Gogs path traversal vulnerability after evidence of active exploitation.
