CVE-2026-52734 ZEBRA: Unbounded memory leak in mempool download pipeline via timeout path cancel_handles retention

ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, an unauthenticated P2P peer can cause the mempool download pipeline to retain transactions after verification reaches the outer RATELIMITDELAY timeout. In zebrad/src/components/mempool/downloads.rs, Downloads::pollnext removed...

CVE-2026-52734

In Downloads::poll_next() (downloads.rs:215-228), the timeout error path (Err(elapsed)) skips cancel_handles.remove() because tokio::time::error::Elapsed carries no transaction ID, so each timed-out entry retains up to ~9 MB of transaction data. With no GC or cap, an unauthenticated peer causes m...
