The Same Zero: Why Identical ASR Can Imply Different Guarantees in LLM-Agent Security

LLM-agent security has produced a dense landscape of defenses - prompt hardening, content filters, permission gates, sandboxes - yet no framework tells a deployer what a defense actually guarantees, or where that guarantee comes from. We apply Verification Autonomy Levels VAL - L0: LLM...

CVE-2026-104437

The Zebra node (versions before 4.4.0 ) is vulnerable to a consensus divergence vulnerability in V5 transparent signature verification. The root cause is that Zebra computes a ZIP-244 digest for SIGHASH_SINGLE inputs that lack corresponding outputs instead of failing, whereas zcashd correctly rej...

CVE-2026-104431 Zebra before 6.0.0 Denial of Service via Synchronous Script FFI Verification

Zebra before 6.0.0 contains a denial of service vulnerability that allows unauthenticated peers to stall Tokio workers by submitting mempool transactions requiring expensive synchronous script verification. Attackers can send non-standard high-sigop P2SH transactions that reach...

CVE-2026-104423 Zebra before 6.2.1 Denial of Service via Uncapped V6 Shielded Proof Verification

Zebra zebrad before 6.2.1 contains an asymmetric resource consumption vulnerability that allows unauthenticated peers to stall block verification by pushing V6 mempool transactions with invalid Halo2 proofs. Attackers can flood the shared unprioritized Halo2 verification queue with zero-fee...

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...
