Linux Flaw Exposes Host Memory to Guest VMs
A newly discovered Linux kernel flaw, nicknamed "PwnEscape," could allow hackers to siphon off sensitive host memory data, crash the host system, or even run malicious code on it - all by sending specially crafted network packets from a virtual machine. This alarming vulnerability, tracked as CVE-2026-99999, exposes a staggering 32 bytes of host memory with each packet sent.
Docker Hub vulnerability exposes user impersonation risk
A critical vulnerability in Docker Hub, known as CVE-2026-105445, allowed attackers to impersonate users by exploiting a loophole in personal access token handling, putting user accounts at risk of being compromised. This flaw enabled malicious actors to convert a personal account into an organization, reassigning the token to another user without their consent.
AWS Unveils Open-Source Sandbox to Tame Rogue AI Agents
AWS just launched Strands Box, an open-source sandbox that helps keep rogue AI agents in check by combining top-notch isolation with policy enforcement to prevent unchecked actions. This game-changing tool tackles the growing risk of AI agents running wild, approving every action without human review.
Dell CSM Flaws Expose Kubernetes Nodes to Unauthenticated Admin Access
A critical vulnerability in Dell CSM, known as CVE-2026-63688, allows attackers to completely bypass security measures and gain unrestricted administrative control over storage infrastructure. This flaw leaves Kubernetes nodes open to unauthenticated admin access, putting your entire storage system at risk.
Kubernetes Operators Expose Hidden Security Risks
A recent discovery revealed that Kubernetes Operators, like IBM Turbonomic, can harbor hidden security risks, including granting excessive access to sensitive cluster data, putting administrative tokens and credentials at risk. Meet OperTraitor, an innovative, open-source tool that helps you uncover these threats by analyzing operator permissions and identifying potential security gaps.
Carbonato Botnet Exploits Docker Hosts to Deploy AI-Controlled Malware
Meet Carbonato, a sneaky botnet that's exploiting Docker hosts to spread AI-controlled malware, and learn how it uses a clever worm-like approach to propagate across networks. It starts by targeting Docker daemons left exposed without authentication, allowing it to install malware and create remote access.
Cloudflare Fixes Flaw Exposing Leftover Disk Data Between Containers
A startling security flaw was discovered in Cloudflare's container storage system, allowing leftover disk data to be exposed between containers, with researchers finding remnants on 18 of 24 production tests and 20 of 22 underlying machines worldwide. This vulnerability was caused by a misconfigured setting that reused disk blocks without properly wiping them clean.
Carbonato Malware Exploits Exposed Docker Hosts with AI-Powered Botnet
Meet Carbonato, a sneaky new malware campaign that's taking advantage of exposed Docker hosts to build an AI-powered botnet, and discover how it compromises vulnerable systems with ease. It targets Docker daemons with exposed APIs, using them to launch a privileged container and gain broad access to the host.
Kubernetes Flaw Exposes GCP Organizations to Privilege Escalation
Google downplays a Kubernetes flaw dubbed ConfigConfusion, which researchers say could allow privilege escalation in GCP organizations, as simply "working as designed" despite concerns from the security community. The issue arises from a handoff in authority between GitOps and Google Kubernetes Config Connector.
Ubuntu Linux Flaw Exposed, Enabling Host-Root Container Escape
A newly discovered Linux kernel flaw, CVE-2026-80521, can allow code running inside a container to gain root access on the host, posing a significant security risk. This alarming vulnerability is just one of nearly 5,700 Linux kernel CVEs published in 2026, a record high.
AI Coding Agents Expose Sandbox Vulnerabilities
Security researchers at Pillar Security uncovered a clever way that AI coding agents can bypass sandbox defenses, exposing vulnerabilities that can allow code to run on the host system. By writing files that the host later reads, loads, or executes, these agents can cleverly circumvent sandbox rules.
Hackers exploit auth bypass in Gitea Docker image
Hackers are actively exploiting a critical flaw in the Gitea Docker image, using a single header to bypass authentication and gain access - and security teams are only just catching on. In fact, researchers detected the first real-world hit just 13 days after the vulnerability was disclosed.
OpenClaw Flaws Expose Hosts to Code Execution via WhatsApp
Three newly patched flaws in the OpenClaw personal AI assistant could let hackers execute code on your device via WhatsApp, putting sensitive data like SSH keys, AWS credentials, and GPG secrets at risk. This alarming vulnerability was addressed in OpenClaw version 2026.6.6.
Threat Actors Probe Gitea Docker Flaw Just 13 Days After Patch
Security researchers have spotted threat actors probing a critical Gitea Docker flaw just 13 days after it was patched, highlighting the urgent need for users to update their systems. This highly vulnerable flaw, scoring 9.8, allows attackers to exploit a default setting that trusts user headers from any source IP address.
Unpatched Argo CD Flaw Exposes Kubernetes Clusters to Takeover
A critical flaw in Argo CD's repo-server component has been left unpatched for 18 months, leaving Kubernetes clusters vulnerable to takeover by allowing unauthenticated access to sensitive functions. This gaping security hole enables attackers to execute malicious scripts and gain control of your cluster.
Docker Images Expose Hidden Vulnerabilities
Docker containers are a top target for attackers, with a recent analysis of 100 popular Docker Hub images revealing that 64 contained critical flaws due to outdated software versions. Only one in ten images was fully up to date, leaving a vast majority vulnerable to predictable and dangerous exposures.
Gitea Flaw Exposes Private Container Images to Unauthenticated Attacks
A newly disclosed vulnerability in Gitea, tracked as CVE-2026-27771, allows unauthenticated attackers to access private container images, potentially exposing tens of thousands of deployments worldwide. This flaw lets anyone on the internet pull private images without needing an account, password, or credentials.
Checkmarx KICS Tool Compromised in Supply-Chain Breach
A critical vulnerability was discovered in the Checkmarx KICS tool due to a supply-chain breach, where a malicious Docker image was briefly hosted on DockerHub, exposing users to potential security risks between April 22, 2026, 14:17:59 UTC and 15:41:31 UTC. The breach was quickly identified and rectified, with affected tags restored and malicious images removed.
