An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-41584 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- zebra-chain (crates.io): affected all versions; fixed in 6.0.2\n- zebra-chain (crates.io): affected all versions; fixed in 6.0.2\n- zebrad (crates.io): affected all versions; fixed in 4.3.1\n- zebrad (crates.io): affected all versions; fixed in 4.3.1\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-41584/ (Markdown: https://insights.sbomify.com/CVE-2026-41584/index.md)","id":"CVE-2026-41584","markdown":"https://insights.sbomify.com/CVE-2026-41584/index.md","name":"CVE-2026-41584","record":{"aliases":["GHSA-452v-w3gx-72wg"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Zcash node software","requires_auth":"none","summary":"An attacker can crash a Zebra node by sending a crafted transaction with an identity value in the rk field, causing a panic.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"zebra-chain","vendor":"zfnd"},{"product":"zebrad","vendor":"zfnd"}],"cvss":{"score":9.2,"severity":"critical","source":"cna","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","version":"4.0"},"cwes":[{"id":"CWE-617","name":"Reachable Assertion"}],"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.
