CVE-2026-104436
Zebra before 4.5.0 contains an uncontrolled resource consumption vulnerability that allows remote P2P peers to exhaust blocking-pool threads by sending oversized block locator vectors. Attackers can send getblocks or getheaders messages with up to 65,535 locator hashes, triggering per-hash chain...

GHSA-443G-GWGP-49X4 zebrad vulnerable to getblocks/getheaders locator CPU amplification via uncapped vector length
Am I affected You are affected if: 1. You run zebrad up to and including v4.4.1. 2. Your node accepts inbound P2P connections. Summary The readgetblocks and readgetheaders codec paths accepted block locator vectors up to approximately 65,535 entries the generic TrustedPreallocate ceiling derived...
CVE-2026-34069 nimiq-consensus panics via RequestMacroChain micro-block locator
nimiq/core-rs-albatross is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. In versions 1.2.2 and below, an unauthenticated p2p peer can cause the RequestMacroChain message handler task to panic. Sending a RequestMacroChain message where the...
CVE-2026-34069
CVE-2026-34069 affects the Rust implementation of Nimiq’s PoS consensus (nimiq/core-rs-albatross). In versions 1.2.2 and earlier, an unauthenticated p2p peer can trigger a panic in the RequestMacroChain message handler when the first locator hash on the victim’s main chain is a micro block hash (...

GHSA-48M6-486P-9J8P nimiq-consensus panics via RequestMacroChain micro-block locator
Impact An unauthenticated p2p peer can cause the RequestMacroChain message handler task to panic by sending a RequestMacroChain message where the first locator hash that is on the victim’s main chain is a micro block hash not a macro block hash. In RequestMacroChain::handle, the handler selects t...
