01/07/2026-01/14/2026 Gogs Vulnerability, Microsoft Fixes 114 Windows Flaws, Critical Node.js Vulnerability And More

1. CISA Flags Actively Exploited Gogs Vulnerability With No Patch

A high-severity vulnerability in the self-hosted Git service Gogs is being actively exploited, prompting an alert from CISA. The flaw is tracked as CVE-2025-8110 and carries a CVSS v4.0 score of 8.7. The issue stems from improper handling of symbolic links in Gogs’ PutContents API, allowing authenticated attackers to overwrite files outside a repository and achieve remote code execution. Wiz researchers uncovered the flaw while investigating malware infections and found it was exploited as a zero-day, bypassing earlier protections. More than 700 Gogs instances have already been compromised, and about 1,600 servers remain internet-exposed. No official patch is available yet, though fixes are pending. Until updates are released, organizations are urged to restrict access, disable open registration, and closely monitor for suspicious activity.

2. Microsoft Fixes 114 Windows Flaws in January 2026 Patch, One Actively Exploited

Microsoft has released its first Patch Tuesday update of 2026, fixing 114 security vulnerabilities, including one actively exploited in the wild. Eight flaws are rated Critical and 106 Important, with privilege escalation issues making up the largest category. The update ranks as the third-largest January Patch Tuesday on record.

The actively exploited flaw, CVE-2026-20805 (CVSS 5.5), is an information disclosure vulnerability in the Desktop Window Manager (DWM) that could help attackers undermine protections like ASLR. While exploitation details remain limited, CISA has added it to its KEV catalog, requiring U.S. federal agencies to patch by February 3, 2026.

Microsoft also addressed Edge browser flaws, removed vulnerable legacy Agere modem drivers, and fixed a Secure Boot certificate expiration bypass that could weaken firmware trust. Another high-priority issue is a privilege escalation flaw in Windows Virtualization-Based Security Enclave that could allow attackers to compromise core system protections.

3. Critical Node.js Vulnerability Can Cause Server Crashes via async_hooks Stack Overflow

Node.js has released security updates to fix a critical denial-of-service (DoS) issue that could impact “virtually every production Node.js app.” Tracked as CVE-2025-59466 (CVSS 7.5), the flaw occurs when stack space is exhausted in user code while async_hooks is enabled. Instead of throwing a catchable error, Node.js may abruptly exit with code 7, allowing attackers to crash applications using unsanitized, recursion-based input. The issue affects many popular frameworks and monitoring tools that rely on AsyncLocalStorage, including React Server Components, Next.js, and major APM platforms such as Datadog and New Relic. All Node.js versions from 8.x through 18.x are impacted, though only supported releases have been patched.

Fixes are available in Node.js 20.20.0, 22.22.0, 24.13.0, and 25.3.0. Node.js also addressed three additional high-severity vulnerabilities involving data leakage, file access via symlinks, and remote DoS. Users are strongly urged to update promptly.

4. Trend Micro Fixed a Remote Code Execution in Apex Central

Trend Micro has patched three security vulnerabilities in its Apex Central on-premise management console that could enable remote code execution (RCE) or denial-of-service (DoS) attacks. The flaws, discovered by Tenable in August 2025 and tracked as CVE-2025-69258, CVE-2025-69259, and CVE-2025-69260, affect Windows installations running Apex Central versions prior to Build 7190.

The most critical issue, CVE-2025-69258 (CVSS 9.8), is a LoadLibraryEx RCE vulnerability that allows an unauthenticated attacker to load a malicious DLL and execute code with SYSTEM privileges. Tenable released proof-of-concept exploit code demonstrating the attack. The other two flaws, both rated 7.5, are DoS vulnerabilities caused by an unchecked NULL return value and an out-of-bounds read, respectively.
Trend Micro addressed all three issues in Critical Patch Build 7190 and urges customers to apply updates promptly and restrict remote access.

12/31/2026-01/07/2026 ISE Security Vulnerability, Ni8mare Flaw Gives Unauthenticated Control Of n8n Instances, New Veeam Vulnerabilities And More

1. Cisco Patches ISE Security Vulnerability After Public PoC Exploit Release

Cisco has issued patches for a medium-severity flaw, CVE-2026-20029 (CVSS: 4.9), in its Identity Services Engine (ISE) and ISE Passive Identity Connector. This vulnerability, present in the licensing feature, allows an authenticated administrator to read arbitrary files via malicious XML uploads. A public proof-of-concept exploit is available. Affected versions include releases earlier than 3.2 and specific 3.2 to 3.4 releases; version 3.5 is not vulnerable. No workarounds exist. Concurrently, Cisco fixed two other medium-severity Snort 3 bugs—CVE-2026-20026 (denial-of-service) and CVE-2026-20027 (information disclosure)—affecting multiple products. Given frequent targeting of Cisco vulnerabilities, users must apply updates promptly for protection.

2. Ni8mare Flaw Gives Unauthenticated Control Of n8n Instances

A critical vulnerability in the n8n workflow automation platform, tracked as CVE-2026-21858 (CVSS 10.0) and dubbed Ni8mare, allows unauthenticated attackers to fully compromise affected instances. Discovered by Cyera researchers, the flaw enables arbitrary file read by abusing how n8n Webhooks handle uploaded data in certain form-based workflows.

The issue arises when workflows process files without validating the request’s Content-Type. Attackers can craft non-multipart requests and manually define file paths, tricking n8n into copying and exposing sensitive system files such as /etc/passwd. With access to configuration files and the local SQLite database, attackers can extract authentication secrets, forge an admin session cookie, and bypass login protections.

Once authenticated as an admin, attackers can achieve full remote code execution using built-in workflow nodes. The vulnerability affects all n8n versions up to 1.65.0 and was fixed in version 1.121.0 (November 2025). A compromised n8n instance can expose credentials, tokens, and connected systems, making the impact severe.

3. New Veeam Vulnerabilities Expose Backup Servers to RCE Attacks

Veeam has released security updates to fix multiple flaws in its Backup & Replication (VBR) software, including a high-severity remote code execution vulnerability tracked as CVE-2025-59470. The flaw affects Veeam Backup & Replication version 13.0.1.180 and all earlier v13 builds.

The vulnerability allows attackers with Backup or Tape Operator roles to achieve remote code execution as the postgres user by sending malicious parameters. While initially rated critical, Veeam downgraded the issue to high severity because exploitation requires highly privileged access. Two additional flaws were also fixed: CVE-2025-55125 (high) and CVE-2025-59468 (medium), both enabling RCE under specific conditions.

The issues were patched in Veeam Backup & Replication 13.0.1.1071, released on January 6. VBR is widely used by enterprises and managed service providers and is frequently targeted by ransomware groups, as compromising backup servers can enable data theft and prevent recovery.

4. Critical AdonisJS Bodyparser Flaw (CVSS 9.2) Enables Arbitrary File Write on Servers

Users of the @adonisjs/bodyparser npm package are urged to update after disclosure of a critical path traversal vulnerability that could allow arbitrary file writes on servers. Tracked as CVE-2026-21440 (CVSS 9.2), the flaw affects AdonisJS multipart file uploads when developers use MultipartFile.move() without sanitizing filenames or providing the options parameter.

In such cases, attackers can supply crafted filenames containing traversal sequences, enabling them to write files outside the intended upload directory and potentially overwrite sensitive files. If application code or configuration files are overwritten and later executed, remote code execution may be possible, depending on deployment and permissions. The issue affects versions ≤10.1.1 and ≤11.0.0-next.5, and is fixed in 10.1.2 and 11.0.0-next.6.

The disclosure coincides with another high-severity path traversal flaw in jsPDF (CVE-2025-68428, CVSS 9.2), patched in version 4.0.0, which could expose arbitrary local files in Node.js environments.

5. RondoDox Botnet Exploits Critical React2Shell Flaw to Hijack IoT Devices and Web Servers

Researchers have uncovered a nine-month-long campaign targeting IoT devices and web applications to build the RondoDox botnet. As of December 2025, attackers are exploiting React2Shell (CVE-2025-55182, CVSS 10.0), a critical flaw in React Server Components and Next.js that enables unauthenticated remote code execution, according to CloudSEK.

Shadowserver estimates 90,000+ instances remain vulnerable worldwide, with the majority in the U.S. RondoDox, active since early 2025, has expanded by abusing multiple N-day flaws, including CVE-2023-1389 and CVE-2025-24893. The campaign evolved from manual scanning to large-scale automated exploitation.

Recent attacks scan for vulnerable Next.js servers and deploy crypto miners, botnet loaders, and a Mirai variant. One tool aggressively removes competing malware and establishes persistence via cron jobs. Mitigations include patching Next.js, isolating IoT devices, deploying WAFs, monitoring suspicious processes, and blocking known C2 infrastructure.

12/17/2025-12/24/2025 Critical n8n Flaw (CVSS 9.9) Enables Arbitrary Code Execution, New UEFI Flaw Enables Early-Boot DMA Attacks And More

1. Critical n8n Flaw (CVSS 9.9) Enables Arbitrary Code Execution Across Thousands of Instances

A critical security vulnerability has been disclosed in the n8n workflow automation platform that could allow arbitrary code execution under certain conditions. The flaw, tracked as CVE-2025-68613, has a CVSS score of 9.9  It has approximately 57,000 weekly downloads on npm. According to the maintainers, expressions provided by authenticated users during workflow configuration may be evaluated in an execution context that is not properly isolated from the underlying runtime. An authenticated attacker could exploit this behavior to execute arbitrary code with the privileges of the n8n process, potentially leading to full system compromise, including data theft, workflow manipulation, and system-level operations. The vulnerability affects all versions from 0.211.0 up to but not including 1.120.4 and has been patched in 1.120.4, 1.121.1, and 1.122.0. Users are strongly urged to update immediately or restrict workflow permissions and harden deployments if patching is delayed.

2. U.S. CISA Adds a Flaw in WatchGuard Fireware OS to its Known Exploited Vulnerabilities Catalog

CISA has added a critical WatchGuard Firebox OS vulnerability, CVE-2025-14733 (CVSS 9.3), to its KEV catalog after active exploitation was confirmed. The flaw is an out-of-bounds write issue in WatchGuard Fireware OS that can be exploited remotely and without authentication via exposed IKEv2 VPN services. When Mobile User VPN or Branch Office VPN with IKEv2 is configured using a dynamic gateway peer, specially crafted network traffic can trigger improper memory handling, allowing attackers to execute arbitrary code on affected Firebox devices. The vulnerability impacts multiple Fireware OS branches, including 11.10.2–11.12.4_Update1, 12.0–12.11.5, and 2025.1–2025.1.3, putting VPN gateways at risk of full compromise.   WatchGuard has released patches, Indicators of Attack, and mitigation guidance. CISA has ordered federal agencies to remediate the flaw by December 26, 2025. Organizations are strongly urged to apply updates immediately, rotate secrets after patching, and restrict exposure if fixes cannot be deployed at once.

3. New UEFI Flaw Enables Early-Boot DMA Attacks on ASRock, ASUS, GIGABYTE, MSI Motherboards

Certain motherboard models from ASRock, ASUS, GIGABYTE, and MSI are affected by a firmware vulnerability that exposes systems to early-boot DMA attacks despite UEFI and IOMMU protections being enabled. Discovered by Nick Peterson and Mohamed Al-Sharifi of Riot Games, the flaw stems from firmware incorrectly reporting that DMA protection is active while failing to initialize the IOMMU during early boot.

This gap allows a malicious PCIe DMA-capable device with physical access to read or modify system memory before the operating system and its security controls load, potentially enabling pre-boot code injection and undermining system integrity. CERT/CC warns attackers could access sensitive data or alter the system’s initial state.

The issue affects multiple Intel and AMD chipset families and is tracked under CVE-2025-14304, CVE-2025-11901, CVE-2025-14302, and CVE-2025-14303, each with a CVSS score of 7.0. Vendors are releasing firmware updates to fix IOMMU initialization. Users are strongly advised to apply patches promptly, especially in environments where physical access cannot be fully controlled.

4. Exploited SonicWall Zero-Day Patched (CVE-2025-40602)

SonicWall has released a hotfix for a local privilege escalation vulnerability, CVE-2025-40602, affecting Secure Mobile Access (SMA) 1000 appliances and warned that the flaw has been exploited in the wild. The vulnerability was reportedly chained with CVE-2025-23006 to achieve unauthenticated remote code execution with root privileges. CVE-2025-23006, patched in January 2025, is a deserialization of untrusted data flaw in the Appliance and Central Management Consoles that allows unauthenticated attackers to execute OS commands. The newly disclosed CVE-2025-40602 also impacts the Appliance Management Console and, due to missing authorization checks, enables attackers with local access to escalate privileges to root when chained with the earlier bug.

SonicWall credited researchers from Google’s Threat Intelligence Group for reporting the issue, though no indicators of compromise have been shared. Customers are urged to upgrade to 12.4.3-03245 or 12.5.0-02283 and restrict management interface access. Even if earlier patches are applied, deploying the latest updates remains essential to fully mitigate the risk.
