LMDeploy RCE Vulnerability CVE-2026-33626 Weaponised in the Wild 13 Hours After Disclosure
A critical remote code execution flaw in LMDeploy, a widely used LLM inference serving framework, was exploited in active attacks just 13 hours after public disclosure. Organisations running self-hosted AI inference infrastructure must treat these platforms with the same urgency as any internet-exposed web application server — because attackers already do.
KTransformers AI Inference Framework Exposes Unauthenticated RCE via Pickle Deserialization — CVSS 9.8
CVE-2026-26210 is a CVSS 9.8 pre-authentication RCE in KTransformers, a popular AI inference acceleration framework. The scheduler's ZMQ ROUTER socket binds to all interfaces with no authentication and deserialises arbitrary pickle payloads — any network-reachable host can execute code on the inference server.
Microsoft Bing Remote Code Execution via Deserialization — CVSS 10.0 Patch Now
A critical CVSS 10.0 unauthenticated RCE vulnerability in Microsoft Bing allows attackers to execute arbitrary code over the network via unsafe deserialization. Patched in April 2026 Patch Tuesday — update immediately.
Wormable Windows TCP/IP Race Condition RCE (CVE-2026-33827) — IPv6-Enabled Networks Face EternalBlue-Class Propagation Risk
A race condition in the Windows TCP/IP stack allows unauthenticated remote code execution against systems with IPv6 or IPSec enabled, demonstrated at Pwn2Own 2026 and patched in April's Patch Tuesday. The vulnerability's wormable characteristics — no user interaction, no authentication, network-adjacent propagation — place it in the same risk category as EternalBlue for environments that have not applied the April update.
Marimo AI Notebook RCE CVE-2026-39987 Exploited at Scale — 662 Events in Three Days, NKAbuse Malware Deployed
CVE-2026-39987 (CVSS 9.3) in the Marimo Python notebook has been weaponised at scale, with Sysdig recording 662 exploitation events over three days and attackers completing credential theft within minutes of gaining access. The unauthenticated WebSocket RCE is being used to deploy NKAbuse, a multi-platform malware using the NKN peer-to-peer network for command and control. Upgrade to Marimo 0.23.0 immediately.
Google Antigravity AI Coding Assistant Had Two Chained Vulnerabilities — Prompt Injection to RCE and Reinstall-Surviving Backdoor
Mindgard researchers discovered two vulnerabilities in Google's Antigravity AI coding assistant: a prompt injection via the find_by_name tool that bypasses Strict Mode to achieve code execution, and a persistent backdoor via workspace trust that survives reinstallation of the IDE extension. Google has patched both; update immediately and audit workspace trust settings.
Four Critical Cisco Flaws: Webex SSO User Impersonation (CVSS 9.8) and ISE Root Code Execution (CVSS 9.9)
Cisco patched four critical vulnerabilities across Webex Services and Identity Services Engine. CVE-2026-20184 allows unauthenticated attackers to impersonate any Webex user via crafted SSO tokens. Three ISE flaws at CVSS 9.9 let read-only admins execute arbitrary commands as root. Webex deployments with SSO require urgent manual action — Cisco's cloud fix is not sufficient without administrator intervention.
Public Exploit Released for Critical FortiSandbox RCE (CVE-2026-39808, CVSS 9.1) — Unauthenticated Root Access
A public proof-of-concept exploit has been released for CVE-2026-39808, a critical OS command injection vulnerability in Fortinet FortiSandbox that allows unauthenticated attackers to execute arbitrary commands as root via a single HTTP request. A companion authentication bypass flaw (CVE-2026-39813) affects the same versions. Patch to FortiSandbox 4.4.9 or 5.0.6 immediately.
Five-Year-Old ShowDoc RCE Flaw CVE-2025-0520 (CVSS 9.4) Now Under Active Exploitation — Over 2,000 Instances Exposed

The flaw, patched in October 2020 but present in thousands of unupgraded installations, allows file upload exploitation to deploy web shells. More than 2,000 publicly accessible ShowDoc instances remain vulnerable.
CVE-2026-33826: Windows Active Directory RCE via Crafted RPC Calls — Patch Now
A critical remote code execution flaw in Windows Active Directory allows any authenticated domain user to execute arbitrary code on domain controllers and other AD-joined servers by sending specially crafted RPC calls. Rated CVSS 8.0 and assessed by Microsoft as 'Exploitation More Likely', CVE-2026-33826 poses a serious lateral-movement and domain-compromise risk for every Windows Server environment. The April 2026 Patch Tuesday update provides the only full remediation.
CVE-2026-33824: Critical Windows IKE Service RCE Demands Urgent Patching
A CVSS 9.8 double-free vulnerability in the Windows Internet Key Exchange service allows unauthenticated remote attackers to achieve SYSTEM-level code execution on all supported Windows versions. With no user interaction required and confirmation of pre-patch exploitation, every unpatched Windows host with IKEv2 enabled is at immediate risk. Apply the April 2026 Patch Tuesday update or block UDP ports 500 and 4500 immediately.
nginx-ui CVE-2026-33032 Actively Exploited — Unauthenticated Full Server Takeover
A critical authentication bypass vulnerability (CVSS 9.8) in the nginx-ui web management interface allows any network attacker to take complete control of the underlying Nginx server without credentials. Over 2,600 instances are internet-exposed and the flaw is being actively exploited. Update to version 2.3.4 immediately.

Adobe Acrobat Reader Zero-Day CVE-2026-34621 Exploited for Four Months Before Patch
Adobe has released an emergency patch for CVE-2026-34621, a prototype pollution vulnerability in Acrobat Reader that has been actively exploited since at least November 2025. Opening a crafted PDF triggers JavaScript execution that fingerprints the victim's system and can deploy RCE and sandbox escape payloads. CISA added the CVE to the KEV catalogue the same day, requiring federal agencies to patch by 27 April.
Second Critical FortiClient EMS Flaw in a Month: CVE-2026-21643 Pre-Auth SQL Injection Exposed
