    AWS, Google, and Vercel Agent Flaws Let Attackers Trigger Tools Without Running the Model

    What happened

    AWS, Google, and Vercel have patched flaws in their agent infrastructure that allowed attackers to trigger tools without running the AI model. This bypasses system prompts, content filters, and model-level guardrails.

    Why it ranks #4

    Critical vulnerabilities in widely used cloud AI infrastructure affecting trust boundaries and security controls.

    Who should care

    Application security teams, Cloud security teams

    What to do

    Ensure all AI agent integrations using AWS, Google, or Vercel are updated to the latest patched versions.

    Paperclip AI Flaws Let Attackers Run Host Commands via Malicious Agent Imports

    What happened

    Two security flaws in the Paperclip AI control plane allow attackers to execute host commands by importing and starting malicious agents. A third flaw can expose sensitive data via API routes.

    Why it ranks #5

    Direct RCE capability within an AI agent orchestration platform, representing a significant application-security risk.

    Who should care

    Application security teams, Cloud security teams

    What to do

    Restrict the ability to import agents from untrusted sources in Paperclip environments.

    Attackers Compile khunt Inside Oracle to Turn SQL Injection Into Windows SYSTEM Access

    What happened

    Attackers are using a SQL injection flaw in public web applications to install the 'khunt' post-exploitation toolkit inside Oracle databases. The toolkit is compiled as stored schema objects, allowing Windows SYSTEM access without writing executables to disk.

    Why it ranks #6

    Material threat actor operation demonstrating a novel technique for stealthy persistence and privilege escalation in enterprise databases.

    Who should care

    Application security teams, SOC and incident response teams

    What to do

    Audit Oracle database schema objects for unauthorized Java source code or stored procedures.

    Chinese-Made Zbtlink Routers Ship With Backdoor That Opens Unauthenticated Root Shells

    What happened

    At least 20 models of Zbtlink routers ship with a factory-installed backdoor that provides unauthenticated root shell access. The implant is present in all available firmware images from the last two years and beacons to Chinese infrastructure.

    Why it ranks #7

    Significant supply chain compromise involving hardware backdoors, though lower priority than active enterprise software exploitation.

    Who should care

    IT and platform operations, SOC and incident response teams

    What to do

    Identify and replace Zbtlink routers within the network environment.

    Non-human identities are 91% of everything active in production

    What happened

    Research indicates that non-human identities (NHIs) account for 91% of active production traffic. Because only 20% of this activity occurs during business hours, rogue API calls from compromised machine credentials often evade detection.

    Why it ranks #10

    Defensive research highlighting a systemic identity risk in cloud environments with clear operational consequences for monitoring.

    Who should care

    Cloud security teams, Identity and access teams, SOC and incident response teams

    What to do

    Implement behavioral monitoring and anomaly detection specifically for non-human service accounts.
