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-2022-26534 in the wild and no public exploit code.\n\nAffected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2022-26534/ (Markdown: https://insights.sbomify.com/CVE-2022-26534/index.md)","id":"CVE-2022-26534","markdown":"https://insights.sbomify.com/CVE-2022-26534/index.md","name":"CVE-2022-26534","record":{"aliases":["GHSA-gf3h-q37j-xmm8"],"analysis":{"component_type":"other","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Blockchain platform","requires_auth":"none","summary":"A malicious node can cause excessive view changes in FISCO-BCOS, stopping block generation and causing denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fisco-bcos","vendor":"fisco-bcos"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"FISCO-BCOS release-3.0.0-rc2 was discovered to contain an issue where a malicious node, via a malicious viewchange packet, will cause normal nodes to change view excessively and stop generating blocks.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Denial of service in n/a","id":"CVE-2022-26534","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Command injection in n/a","id":"CVE-2022-26536"},"packages":[],"prev":{"headline":"Cross-site Scripting in Alist","id":"CVE-2022-26533"},"products":["n/a"],"published":"2022-03-16","related":[{"cvss_score":7.5,"headline":"Integer overflow in n/a","id":"CVE-2022-28936","kev_date_added":null,"published":"2022-05-15"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2022-28937","kev_date_added":null,"published":"2022-05-15"},{"cvss_score":7.5,"headline":"Business logic in n/a","id":"CVE-2021-46359","kev_date_added":null,"published":"2022-02-07"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2021-35041","kev_date_added":null,"published":"2021-06-23"},{"cvss_score":4,"headline":"Race condition in FISCO-BCOS","id":"CVE-2024-58131","kev_date_added":null,"published":"2025-04-06"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"A malicious node can cause excessive view changes in FISCO-BCOS, stopping block generation and causing denial of service.","url":"https://insights.sbomify.com/CVE-2022-26534/"}
