Prior to 0.13.1, libp2p-quic could panic during an inbound QUIC handshake when a remote peer presented a valid short-lived libp2p TLS certificate and delayed the final TLS 1.3 handshake fragment until after the certificate expired. In the Quinn post-handshake upgrade path, transports/quic/src/connection/connecting.rs called libp2p_tls::certificate::parse a second time in remote_peer_id and used expect on the result. The repeated wall-clock validity check could reject the now-expired certificate, causing the expect call to terminate any application exposing an affected libp2p-quic listener. This vulnerability is fixed in 0.13.1.","state":0,"publishedAt":"2026-09-15T19:46:13.721+00:00","modifiedAt":"2026-09-17T16:48:19.068+00:00","affected":[{"ecosystem":"Vendor product","name":"rust-libp2p","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"libp2p\",\n                    \"product\": \"rust-libp2p\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.13.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.2,"severity":"HIGH"}],"references":["https://github.com/libp2p/rust-libp2p/security/advisories/GHSA-5hq8-qhww-jm7q","https://github.com/libp2p/rust-libp2p/pull/6525","https://github.com/libp2p/rust-libp2p/commit/212f3774af048e2cecfb2e6b1e08477685e52b22","https://github.com/libp2p/rust-libp2p/commit/e8f35e12c2418b04df6e9cdf036005e8aee3c7a2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-61544","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-61544","identifiers":["CVE-2026-61544"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
