# CVE-2025-32711: M365 Copilot Information Disclosure Vulnerability

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 8.0% , percentile 95: FIRST’s model estimates a 8.0% chance of exploitation activity in the next 30 days, higher than 95% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Editorial verdict: Most can relax. EchoLeak: Zero-Click Data Leak in Microsoft 365 Copilot — 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.
