chore: bump crossbeam-epoch 0.9.18 -> 0.9.20 (RUSTSEC-2026-0204)#148
Merged
Conversation
Fixes the one vulnerability flagged by `cargo audit` on main: an invalid pointer dereference in crossbeam-epoch's `fmt::Pointer` impl. The advisory was published after the 0.3.1 release, so main's audit now fails on it. Transitive patch bump, lockfile-only, no manifest change; audit clean.

cargo auditonmainnow fails on RUSTSEC-2026-0204 — an invalid pointer dereference incrossbeam-epoch'sfmt::Pointerimpl forAtomic/Shared. The advisory was published after the 0.3.1 release, so it's newly reachable by the CI audit job (and by anyone building frommain).Fix per the advisory: upgrade to
>=0.9.20. This is a transitive patch bump — lockfile-only, no manifest change.cargo auditis clean afterward (remaining items are allowed unmaintained warnings). quinn-proto is already at the patched 0.11.15 on main, so no other vulnerabilities remain.Surfaced while bumping ant-sdk's ffi/antd onto ant-core 0.3.1 — fixing at the source so downstream consumers inherit it on the next release.
