| CVE-2026-35405 | 2 Libp2p, Protocol | 2 Rust-libp2p, Libp2p | 2026-04-24 | 7.5 High |
| libp2p-rust is the official rust language Implementation of the libp2p networking stack. Prior to 0.17.1, libp2p-rendezvous server has no limit on how many namespaces a single peer can register. A malicious peer can just keep registering unique namespaces in a loop and the server happily accepts every single one allocating memory for each registration with no pushback. Keep doing this long enough (or with multiple sybil peers) and the server process gets OOM killed. This vulnerability is fixed in 0.17.1. | ||||
| CVE-2026-35457 | 2 Libp2p, Protocol | 2 Rust-libp2p, Libp2p | 2026-04-24 | 8.2 High |
| libp2p-rust is the official rust language Implementation of the libp2p networking stack. Prior to 0.17.1, the rendezvous server stores pagination cookies without bounds. An unauthenticated peer can repeatedly issue DISCOVER requests and force unbounded memory growth. This vulnerability is fixed in 0.17.1. | ||||
| CVE-2026-34219 | 1 Libp2p | 2 Libp2p-gossipsub, Rust-libp2p | 2026-04-07 | 5.9 Medium |
| libp2p-rust is the official rust language Implementation of the libp2p networking stack. Prior to version 0.49.4, the Rust libp2p Gossipsub implementation contains a remotely reachable panic in backoff expiry handling. After a peer sends a crafted PRUNE control message with an attacker-controlled, near-maximum backoff value, the value is accepted and stored as an Instant near the representable upper bound. On a later heartbeat, the implementation performs unchecked Instant + Duration arithmetic (backoff_time + slack), which can overflow and panic with: overflow when adding duration to instant. This issue is reachable from any Gossipsub peer over normal TCP + Noise + mplex/yamux connectivity and requires no further authentication beyond becoming a protocol peer. This issue has been patched in version 0.49.4. | ||||
| CVE-2026-33040 | 2 Libp2p, Protocol | 2 Libp2p, Libp2p | 2026-03-25 | 7.5 High |
| libp2p-rust is the official rust language Implementation of the libp2p networking stack. In versions prior to 0.49.3, the Gossipsub implementation accepts attacker-controlled PRUNE backoff values and may perform unchecked time arithmetic when storing backoff state. A specially crafted PRUNE control message with an extremely large backoff (e.g. u64::MAX) can lead to Duration/Instant overflow during backoff update logic, triggering a panic in the networking state machine. This is remotely reachable over a normal libp2p connection and does not require authentication. Any application exposing a libp2p Gossipsub listener and using the affected backoff-handling path can be crashed by a network attacker that can reach the service port. The attack can be repeated by reconnecting and replaying the crafted control message. This issue has been fixed in version 0.49.3. | ||||
| CVE-2020-36443 | 1 Libp2p | 1 Libp2p-deflate | 2024-11-21 | 9.8 Critical |
| An issue was discovered in the libp2p-deflate crate before 0.27.1 for Rust. An uninitialized buffer is passed to AsyncRead::poll_read(), which is a user-provided trait function. | ||||
| CVE-2019-15545 | 1 Libp2p | 1 Libp2p | 2024-11-21 | N/A |
| An issue was discovered in the libp2p-core crate before 0.8.1 for Rust. Attackers can spoof ed25519 signatures. | ||||
