What Happened
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday added two security flaws impacting Microsoft SharePoint and Mikrotik RouterOS to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation. The vulnerabilities in question are as follows - CVE-2026-65660 (CVSS score: 8.8) - A code injection vulnerability in Microsoft Office SharePoint
Why It Matters
CISA added actively exploited vulnerabilities in Microsoft SharePoint and MikroTik RouterOS to its Known Exploited Vulnerabilities catalog. The reported flaws enable code execution or unauthorized command execution in affected infrastructure. The article does not identify an AI-specific impact; RealGround analysis is that organizations embedding AI agents or services in these environments should include the affected components in asset inventories, dependency assessments, and remediation planning.
RealGround Analysis
This signal maps to AI supply chain. Organizations using AI agents, LLM APIs, SaaS integrations, or sensitive data workflows should review whether this class of issue could create unauthorized tool execution, data leakage, weak approval gates, or unmanaged supply-chain exposure.
Recommended Actions
- Restrict AI agent tool permissions and production write paths.
- Review sensitive data access across prompts, logs, embeddings, memory, and SaaS integrations.
- Add human approval workflows for high-impact or state-changing actions.
- Run prompt injection and indirect prompt injection tests against affected workflows.
- Document the owner, control gap, and remediation deadline for this risk class.
