# Security digest: June 11, 2025

1 editorial brief.

## Take stock

- Most can relax: EchoLeak . Teams building their own RAG assistants or agents over email, documents or tickets, who should check for the same injection-to-exfiltration pattern.
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.

## Editorial briefs

- **Most can relax** [EchoLeak: Zero-Click Data Leak in Microsoft 365 Copilot](https://erroneo.us/security/briefs/echoleak-m365-copilot-cve-2025-32711/index.md): Nothing to patch: Microsoft fixed it in its cloud service before disclosure and saw no exploitation, but it is the reference case for why AI assistants that read untrusted content need guardrails.

## Known exploited (CISA KEV)

None.

## Critical advisories

None.
