# CVE-2025-0283: Ivanti Connect Secure vulnerability

**Signal:** High exploit likelihood. EPSS ranks it in the top 5% of all CVEs for likely exploitation in the next 30 days. (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 17.5% , percentile 97: FIRST’s model estimates a 17.5% chance of exploitation activity in the next 30 days, higher than 97% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Needs local access needed. Lower urgency for most teams unless an attacker could already run code on the machine.
- Editorial verdict: Check exposure. Ivanti Connect Secure Zero-Day RCE (CVE-2025-0282) — A real zero-day used for espionage and patched in January 2025; if you ran Connect Secure below 22.7R2.5 last winter, a clean patch level today does not prove you were never backdoored.
