Summary
An issue was discovered in RIPE NCC RPKI Validator 3.x through 3.1-2020.07.06.14.28. Missing validation checks on CRL presence or CRL staleness in the X509-based RPKI certificate-tree validation procedure allow remote attackers to bypass intended access restrictions by using revoked certificates. NOTE: there may be counterarguments related to backwards compatibility
Exploit prediction
0.74% chance of exploitation in the next 30 days, higher than 55% of all scored CVEs (FIRST EPSS, 2026-11-08).
