GHSA-qv2r-v3mx-f4pf: zebrad has full node denial of service via non-ASCII LongPollId in getblocktemplateCVE-2026-52731 0 A vulnerability in zebrad up to and including v4.4.1 allows an authenticated RPC client to cause a denial of service by sending a getblocktemplate request with a non-ASCII LongPollId. The RPC handler performs byte-index slicing on the LongPollId string, which panics in Rust when multi-byte UTF-8 characters are present, terminating the entire node process. This affects nodes with RPC enabled via a TCP address and requires attacker authentication to the RPC endpoint. The issue is fixed in zebrad 4.5.0 and zebra-rpc 8.0.0.
