{"cve":"CVE-2026-41584","nvd":{"published":"2026-05-08T15:16:41.240","modified":"2026-06-17T10:46:52.980","status":"Analyzed","description":"ZEBRA is a Zcash node written entirely in Rust. Prior to zebrad version 4.3.1 and prior to zebra-chain version 6.0.2, Orchard transactions contain a rk field which is a randomized validating key and also an elliptic curve point. The Zcash specification allows the field to be the identity (a \"zero\" value), however, the orchard crate which is used to verify Orchard proofs would panic when fed a rk with the identity value. Thus an attacker could send a crafted transaction that would make a Zebra node crash. This issue has been patched in zebrad version 4.3.1 and zebra-chain version 6.0.2.","cvss_v4":{"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:H","score":9.2},"cvss_v3":{"version":"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},"cwes":["CWE-617"],"references":["https://github.com/ZcashFoundation/zebra/security/advisories/GHSA-452v-w3gx-72wg"],"products":["zfnd:zebra-chain","zfnd:zebrad"],"source":"nvd","synced_at":"2026-10-19T22:33:55.586217763+00:00"},"epss":{"cve":"CVE-2026-41584","score":0.00268,"percentile":0.19011,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-452v-w3gx-72wg","url":"https://osv.dev/vulnerability/GHSA-452v-w3gx-72wg","summary":"Zebra has rk Identity Point Panic in Transaction Verification","modified":"2026-05-12T17:36:44.500407Z","packages":[{"ecosystem":"crates.io","name":"zebrad","purl":"pkg:cargo/zebrad","ranges":["<4.3.1"],"fixed":["4.3.1"]},{"ecosystem":"crates.io","name":"zebra-chain","purl":"pkg:cargo/zebra-chain","ranges":["<6.0.2"],"fixed":["6.0.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
