An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-7fw6-6mfj-g3q2 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- ckb (crates.io): affected all versions; fixed in 0.101.1\n- ckb (crates.io): affected all versions; fixed in 0.101.1\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/GHSA-7fw6-6mfj-g3q2/ (Markdown: https://insights.sbomify.com/GHSA-7fw6-6mfj-g3q2/index.md)","id":"GHSA-7fw6-6mfj-g3q2","markdown":"https://insights.sbomify.com/GHSA-7fw6-6mfj-g3q2/index.md","name":"GHSA-7fw6-6mfj-g3q2","record":{"aliases":[],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"CKB blockchain node","requires_auth":"none","summary":"Attackers can cause network forking by submitting transactions with invalid header dependencies, disrupting consensus in CKB nodes.","user_interaction":"not_required","vuln_class":"business_logic"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"### Impact\nfn `HeaderChecker#check_valid` skipped main chain checking after this PR: https://github.com/nervosnetwork/ckb/pull/1646/files#diff-c4e017b67c1b3005ca0c446a9b0879571aa36a858b1f7ddd1b9328a884e3214bR171-R176\n\nIt will cause network forking if one transaction is using a forked block header which is not exists in local node's storage.\n\n### Patches\n\n0.101.1 and later versions","ecosystems":["crates.io"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"ckb: Transaction header_deps validation issue (network forking)","id":"GHSA-7fw6-6mfj-g3q2","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"business_logic","year":"2022"},"n_packages":2,"n_references":null,"packages":[{"ecosystem":"crates.io","fixed":["0.101.1"],"introduced":["0"],"last_affected":[],"package":"ckb","purl":null,"source":"GHSA-7fw6-6mfj-g3q2"},{"ecosystem":"crates.io","fixed":["0.101.1"],"introduced":["0"],"last_affected":[],"package":"ckb","purl":"pkg:cargo/ckb","source":"GHSA-7fw6-6mfj-g3q2"}],"products":null,"published":"2022-11-02","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"Attackers can cause network forking by submitting transactions with invalid header dependencies, disrupting consensus in CKB nodes.","url":"https://insights.sbomify.com/GHSA-7fw6-6mfj-g3q2/"}
