Jul 23, 2026Quinn is a pure-Rust, async-compatible implementation of the IETF QUIC transport protocol.CVE-2026-25800 · Other software · quinn-rs · reported by GitHubHigh 7.5
Quinn is a pure-Rust, async-compatible implementation of the IETF QUIC transport protocol. Starting in version 0.1.0 and prior to version 0.11.15, the `Assembler` component that assembles unordered stream fragments into consecutive chunks of the stream incurs some overhead for non-contiguous fragments. Readers that read from a `RecvStream` in order (through an `AsyncRead` impl for example) will be sensitive to peers that send fragments while leaving out early parts of the stream, and in particular, fragments with many gaps (because these cannot be defragmented). In such a scenario, the receiving connection suffers from high buffer overhead, enabling memory exhaustion. Version 0.11.15 fixes the issue.

Mar 10, 2026Quinn is a pure-Rust, async-compatible implementation of the IETF QUIC transport protocol.CVE-2026-31812 · Other software · quinn-rs · reported by GitHubHigh 8.7
Quinn is a pure-Rust, async-compatible implementation of the IETF QUIC transport protocol. Prior to 0.11.14, a remote, unauthenticated attacker can trigger a denial of service in applications using vulnerable quinn versions by sending a crafted QUIC Initial packet containing malformed quic_transport_parameters. In quinn-proto parsing logic, attacker-controlled varints are decoded with unwrap(), so truncated encodings cause Err(UnexpectedEnd) and panic. This is reachable over the network with a single packet and no prior trust or authentication. This vulnerability is fixed in 0.11.14.

Sep 2, 2024Quinn is a pure-Rust, async-compatible implementation of the IETF QUIC transport protocol.CVE-2024-45311 · Other software · quinn-rs · reported by GitHubHigh 7.5
Quinn is a pure-Rust, async-compatible implementation of the IETF QUIC transport protocol. As of quinn-proto 0.11, it is possible for a server to `accept()`, `retry()`, `refuse()`, or `ignore()` an `Incoming` connection. However, calling `retry()` on an unvalidated connection exposes the server to a likely panic in the following situations: 1. Calling `refuse` or `ignore` on the resulting validated connection, if a duplicate initial packet is received. This issue can go undetected until a server's `refuse()`/`ignore()` code path is exercised, such as to stop a denial of service attack. 2. Accepting when the initial packet for the resulting validated connection fails to decrypt or exhausts connection IDs, if a similar initial packet that successfully decrypts and doesn't exhaust connection IDs is received. This issue can go undetected if clients are well-behaved. The former situation was observed in a real application, while the latter is only theoretical.

Sep 21, 2023quinn-proto is a state machine for the QUIC transport protocol.CVE-2023-42805 · Other software · quinn-rs · reported by GitHubHigh 7.5
quinn-proto is a state machine for the QUIC transport protocol. Prior to versions 0.9.5 and 0.10.5, receiving unknown QUIC frames in a QUIC packet could result in a panic. The problem has been fixed in 0.9.5 and 0.10.5 maintenance releases.

An issue was discovered in the quinn crate before 0.7.0 for Rust. It may have invalid memory access for certain versions of the standard library because it relies on a direct cast of std::net::SocketAddrV4 and std::net::SocketAddrV6 data structures.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
