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-2022-23327 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/ethereum/go-ethereum (Go): affected all versions up to 1.10.12; no fix listed\n- github.com/ethereum/go-ethereum (Go): affected all versions up to 1.10.12; 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/CVE-2022-23327/ (Markdown: https://insights.sbomify.com/CVE-2022-23327/index.md)","id":"CVE-2022-23327","markdown":"https://insights.sbomify.com/CVE-2022-23327/index.md","name":"CVE-2022-23327","record":{"aliases":["GHSA-pvx3-gm3c-gmpr"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Ethereum client","requires_auth":"none","summary":"An attacker can cause a denial of service in Go-Ethereum nodes by flooding the memory pool with high-gas-price future transactions.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"go_ethereum","vendor":"ethereum"}],"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":"A design flaw in Go-Ethereum 1.10.12 and older versions allows an attacker node to send 5120 future transactions with a high gas price in one message, which can purge all of pending transactions in a victim node's memory pool, causing a denial of service (DoS).","ecosystems":["Go"],"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 Go-Ethereum","id":"CVE-2022-23327","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"denial_of_service","year":"2022"},"n_packages":2,"n_references":2,"next":{"headline":"Denial of Service in Go-Ethereum","id":"CVE-2022-23328"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["1.10.12"],"package":"github.com/ethereum/go-ethereum","purl":null,"source":"GHSA-pvx3-gm3c-gmpr"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["1.10.12"],"package":"github.com/ethereum/go-ethereum","purl":"pkg:golang/github.com/ethereum/go-ethereum","source":"GHSA-pvx3-gm3c-gmpr"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2022-23321"},"products":["n/a"],"published":"2022-03-04","related":[{"cvss_score":8.7,"headline":"Go Ethereum affected by DoS via malicious p2p message","id":"CVE-2026-26314","kev_date_added":null,"published":"2026-02-19"},{"cvss_score":7.5,"headline":"go-ethereum vulnerable to denial of service via crafted GraphQL query","id":"CVE-2023-42319","kev_date_added":null,"published":"2023-10-18"},{"cvss_score":7.5,"headline":"Denial of service via malicious p2p message in go-ethereum","id":"CVE-2023-40591","kev_date_added":null,"published":"2023-09-06"},{"cvss_score":7.5,"headline":"Denial of service in go-ethereum","id":"CVE-2021-42219","kev_date_added":null,"published":"2022-03-16"},{"cvss_score":7.5,"headline":"Denial of Service in Go-Ethereum","id":"CVE-2022-23328","kev_date_added":null,"published":"2022-03-04"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2018-20421","kev_date_added":null,"published":"2018-12-24"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2026-07-09","vendors":["n/a"]},"summary":"An attacker can cause a denial of service in Go-Ethereum nodes by flooding the memory pool with high-gas-price future transactions.","url":"https://insights.sbomify.com/CVE-2022-23327/"}
