CVE-2025-4947

libcurl accidentally skips the certificate verification for QUIC connections when connecting to a host specified as an IP address in the URL. Therefore, it does not detect impostors or man-in-the-middle attacks...

PT-2025-23062

Name of the Vulnerable Software and Affected Versions libcurl affected versions not specified Description The issue occurs when libcurl establishes a QUIC connection to a host specified as an IP address in the URL, resulting in the accidental skipping of certificate verification. This failure to...

PT-2025-23063

Name of the Vulnerable Software and Affected Versions libcurl affected versions not specified Description The issue arises from an omission in libcurl's support for pinning the server certificate public key for HTTPS transfers when using QUIC for HTTP/3 with the wolfSSL TLS backend. Although the...

CVE-2024-45397

h2o is an HTTP server with support for HTTP/1.x, HTTP/2 and HTTP/3. When an HTTP request using TLS/1.3 early data on top of TCP Fast Open or QUIC 0-RTT packets is received and the IP-address-based access control is used, the access control does not detect and prohibit HTTP requests conveyed by...

CVE-2024-25678

In LiteSpeed QUIC LSQUIC Library before 4.0.4, DCID validation is mishandled...

CVE-2023-42805

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...

CVE-2023-46239

quic-go is an implementation of the QUIC protocol in Go. Starting in version 0.37.0 and prior to version 0.37.3, by serializing an ACK frame after the CRYTPO that allows a node to complete the handshake, a remote node could trigger a nil pointer dereference leading to a panic when the node...

CVE-2022-30591

quic-go through 0.27.0 allows remote attackers to cause a denial of service CPU consumption via a Slowloris variant in which incomplete QUIC or HTTP/3 requests are sent. This occurs because mtudiscoverer.go misparses the MTU Discovery service and consequently overflows the probe timer. NOTE: the...

CVE-2021-24029

A packet of death scenario is possible in mvfst via a specially crafted message during a QUIC session, which causes a crash via a failed assertion. Per QUIC specification, this particular message should be treated as a connection error. This issue affects mvfst versions prior to commit...

CVE-2020-24944

picoquic before 3rd of July 2020 allows attackers to cause a denial of service infinite loop via a crafted QUIC frame, related to the picoquicdecodeframes and picoquicdecodestreamframe functions and epoch==3...

SUSE CVE-2025-4432

A flaw was found in Rust's Ring package. A panic may be triggered when overflow checking is enabled. In the QUIC protocol, this flaw allows an attacker to induce this panic by sending a specially crafted packet. It will likely occur unintentionally in 1 out of every 232 packets sent or received...

curl: CVE-2025-5025: No QUIC certificate pinning with wolfSSL

Summary: When using wolfSSL as the TLS backend, certificate pinning does not work when using HTTP/3. The code should invoke wsslverifypinned, but it has not been implemented. Affected version curl -V WARNING: this libcurl is Debug-enabled, do not use in production curl 8.13.0 x8664-pc-linux-gnu...

An Automated Blackbox Noncompliance Checker for QUIC Server Implementations

We develop QUICtester, an automated approach for uncovering non-compliant behaviors in the ratified QUIC protocol implementations RFC 9000/9001. QUICtester leverages active automata learning to abstract the behavior of a QUIC implementation into a finite state machine FSM representation. Unlike...

curl: CVE-2025-4947: QUIC certificate check skip with wolfSSL

Summary: When using WolfSSL as the TLS backend, there is an issue where the CN or SAN in the certificate is not verified when connecting to an IP address over HTTP/3. wolfSSLX509checkhost is only called when peer-sni is not NULL. However, when an IP address is specified, peer-sni is NULL, so the...
