CVSS 9.9 Critical EPSS 53.1% · p99 Check exposure
Should you act?
High exploit likelihood
EPSS ranks it in the top 5% of all CVEs for likely exploitation in the next 30 days. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- 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 53.1%, percentile 99: FIRST’s model estimates a 53.1% chance of exploitation activity in the next 30 days, higher than 99% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Editorial verdict: Check exposure. Ivanti Sentry CVE-2026-10520: Pre-Auth Root RCE — Fixed since June 2026, and exploited within two days of a public PoC. Confirm every Sentry runs R10.5.2, R10.6.2, R10.7.1 or later and that port 8443 is not internet-facing. Treat any appliance that was exposed and unpatched as compromised.
