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-fjj4-2q73-jvgc in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- ckb (crates.io): affected from 0.100.0; no fix listed\n- ckb (crates.io): affected from 0.100.0; no fix listed\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-fjj4-2q73-jvgc/ (Markdown: https://insights.sbomify.com/GHSA-fjj4-2q73-jvgc/index.md)","id":"GHSA-fjj4-2q73-jvgc","markdown":"https://insights.sbomify.com/GHSA-fjj4-2q73-jvgc/index.md","name":"GHSA-fjj4-2q73-jvgc","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Nervos CKB library","requires_auth":"none","summary":"An attacker can cause missed cycle calculations in resume mode, potentially leading to denial of service in Nervos CKB script execution.","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\nThe calculation of program load cycles may be missed when executing in resume mode.
