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-mcmr-49x3-4jqm in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- ckb (crates.io): affected from 0.100.0; fixed in 0.102.0\n- ckb (crates.io): affected from 0.100.0; fixed in 0.102.0\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-mcmr-49x3-4jqm/ (Markdown: https://insights.sbomify.com/GHSA-mcmr-49x3-4jqm/index.md)","id":"GHSA-mcmr-49x3-4jqm","markdown":"https://insights.sbomify.com/GHSA-mcmr-49x3-4jqm/index.md","name":"GHSA-mcmr-49x3-4jqm","record":{"aliases":[],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"CKB blockchain node","requires_auth":"none","summary":"Incorrect handling of cycle limits in CKB type_id scripts causes random verification failures, potentially disrupting blockchain operations.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"### Impact\nhttps://github.com/nervosnetwork/ckb/blob/v0.101.2/script/src/verify.rs#L871-L879\nTypeIdSystemScript resume handle is not correct when max_cycles is not enough, `ScriptError::ExceededMaximumCycles` will be raised directly ranther than suspend as expect, and also because script_group execution order is random, so this will happen randomly.","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 type_id script resume may randomly fail","id":"GHSA-mcmr-49x3-4jqm","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"denial_of_service","year":"2022"},"n_packages":2,"n_references":null,"packages":[{"ecosystem":"crates.io","fixed":["0.102.0"],"introduced":["0.100.0"],"last_affected":[],"package":"ckb","purl":null,"source":"GHSA-mcmr-49x3-4jqm"},{"ecosystem":"crates.io","fixed":["0.102.0"],"introduced":["0.100.0"],"last_affected":[],"package":"ckb","purl":"pkg:cargo/ckb","source":"GHSA-mcmr-49x3-4jqm"}],"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":"Incorrect handling of cycle limits in CKB type_id scripts causes random verification failures, potentially disrupting blockchain operations.","url":"https://insights.sbomify.com/GHSA-mcmr-49x3-4jqm/"}
