CVE-2026-104420

The Zebra software (versions before 6.3.0 ) contains a protection mechanism failure that allows unauthenticated peers to evade misbehavior scoring. The vulnerability occurs during an inbound cleanup step where the system wrongly downcasts RouterError to VerifyBlockError , causing the associated s...

CVE-2026-104420 Zebra before 6.3.0 Peer Misbehavior Ban Bypass via Gossiped Blocks

Zebra before 6.3.0 contains a protection mechanism failure that allows unauthenticated peers to evade misbehavior scoring by supplying invalid gossiped blocks. The inbound cleanup step wrongly downcasts RouterError to VerifyBlockError and discards the score, so attackers can repeatedly force bloc...
