CVE-2025-66719

9.1 criticalEPSS 0.4%

Critical (9.1) in free5gc nrf. EPSS 0.4% chance of exploitation in the next 30 days. Fixed in github.com/free5gc/nrf 1.4.1.

An issue was discovered in Free5gc NRF 1.4.0. In the access-token generation logic of free5GC, the AccessTokenScopeCheck() function in file internal/sbi/processor/access_token.go bypasses all scope validation when the attacker uses a crafted targetNF value. This allows attackers to obtain an access token with any arbitrary scope.
