These were fixed in the respective patched releases.","state":0,"publishedAt":"2026-08-19T14:02:14.481+00:00","modifiedAt":"2026-08-21T11:21:07.741+00:00","affected":[{"ecosystem":"Vendor product","name":"libcrux-ecdh","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"celabshq\",\n                    \"product\": \"libcrux-ecdh\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:cargo/libcrux-ecdh\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"0.0.6\"\n                        },\n                        {\n                            \"version\": \"0.0.6\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"libcrux-ed25519","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"celabshq\",\n                    \"product\": \"libcrux-ed25519\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:cargo/libcrux-ed25519\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"0.0.6\"\n                        },\n                        {\n                            \"version\": \"0.0.6\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"libcrux-psq","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"celabshq\",\n                    \"product\": \"libcrux-psq\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:cargo/libcrux-psq\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"0.0.7\"\n                        },\n                        {\n                            \"version\": \"0.0.7\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/celabshq/libcrux/security/advisories/GHSA-435g-fcv3-8j26","https://www.vulncheck.com/advisories/libcrux-before-cryptographic-implementation-bug-fixes"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-76234","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-76234","identifiers":["CVE-2026-76234"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
