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":"2026-09-15T20:17:35.147+00:00","modifiedAt":"2026-09-30T17:51:36.337+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":8.2,"severity":"HIGH"}],"references":["https://github.com/libp2p/rust-libp2p/commit/212f3774af048e2cecfb2e6b1e08477685e52b22","https://github.com/libp2p/rust-libp2p/commit/e8f35e12c2418b04df6e9cdf036005e8aee3c7a2","https://github.com/libp2p/rust-libp2p/pull/6525","https://github.com/libp2p/rust-libp2p/security/advisories/GHSA-5hq8-qhww-jm7q"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-61544","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-248"],"productCriteria":[],"sourceDates":{"published":"2026-09-15T20:17:35.147","lastModified":"2026-09-30T17:51:36.337"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
