May 2026: Monthly Security Bytes

Welcome to our LGA Monthly Security Bytes!

Here, you’ll find bite-sized security developments and practical insights to help you stay ahead of day-to-day security operations.

Active Exploits and Shadow AI Are Expanding Your Attack Surface

Critical vulnerabilities and ungoverned AI adoption are increasing enterprise risk exposure.

Exploits in widely used systems such as Adobe and SonicWall Systems are creating direct entry points into endpoints and remote access environments, while the rapid rise of AI tools like OpenClaw is introducing unmanaged access, data leakage and operational risk.

Without clear governance and monitoring, these risks will remain difficult to detect until impact occurs.

Key Security Updates

1. Critical Infrastructure Vulnerabilities Across Adobe and SonicWall Systems

Adobe Acrobat, Reader and SonicWall SMA1000 are affected by critical flaws that could potentially expose endpoints and remote access to compromise and credential abuse.

Critical Vulnerabilities were identified in the following:

1. Adobe Acrobat & Reader:
 • Acrobat DC (Continuous Track): versions 26.001.21367 and earlier
 • Acrobat Reader DC (Continuous Track): versions 26.001.21367 and earlier
 • Acrobat 2024 (Classic 2024 Track): versions 24.001.30356 and earlier

2. SonicWall Products
• SonicWall SMA1000 versions prior to 12.4.3-03245 (platform-hotfix)
• SonicWall SMA1000 versions prior to 12.5.0-02283 (platform-hotfix)

Resulting in a set of critical vulnerabilities, including CVE-2026-4112, CVE-2026-4113, CVE-2026-4114 and CVE-2026-4116.

2. OpenClaw’s Rise Signals Growing Shadow AI Risk in Enterprise Environments

OpenClaw is an AI assistant that automates complex tasks across systems with minimal input. While it boosts work efficiency, its use outside IT governance is raising security concerns across Singapore firms.

Security experts warn that tools like OpenClaw introduce real risks when deployed without proper controls:

  • Execution risk: Unintended or malicious actions across systems
  • Data exposure: Sensitive data accessed or transmitted without visibility
  • Ecosystem risk: Malicious or unverified “skills” enable exploitation
  • Access risk: Broad permissions amplify impact of misuse or compromise

To mitigate these risks, organisations should implement stronger controls such as sandboxing, zero-trust access and human validation to prevent uncontrolled exposure from Shadow AI.
