An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-0080 exists.\n\nAffected product: mruby/mruby. 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-2022-0080/ (Markdown: https://insights.sbomify.com/CVE-2022-0080/index.md)","id":"CVE-2022-0080","markdown":"https://insights.sbomify.com/CVE-2022-0080/index.md","name":"CVE-2022-0080","record":{"aliases":["DEBIAN-CVE-2022-0080","GHSA-8vcc-hrhr-q8hf","UBUNTU-CVE-2022-0080"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"mruby library","requires_auth":"none","summary":"Attackers can exploit a heap-based buffer overflow in mruby to execute arbitrary code or cause denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntrdev","cpe":[{"product":"mruby","vendor":"mruby"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"mruby is vulnerable to Heap-based Buffer Overflow","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Heap-based Buffer Overflow in mruby/mruby","id":"CVE-2022-0080","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2022"},"n_packages":0,"n_references":2,"next":{"headline":"Generation of Error Message Containing Sensitive Information in livehelperchat/livehelperchat","id":"CVE-2022-0083"},"packages":[],"prev":{"headline":"Generation of Error Message Containing Sensitive Information in star7th/showdoc","id":"CVE-2022-0079"},"products":["mruby/mruby"],"published":"2022-01-02","related":[{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2020-6838","kev_date_added":null,"published":"2020-01-11"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-6839","kev_date_added":null,"published":"2020-01-11"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2020-6840","kev_date_added":null,"published":"2020-01-11"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2018-10199","kev_date_added":null,"published":"2018-04-18"},{"cvss_score":9.3,"headline":"Use-After-Free in str_escape in mruby/mruby in mruby/mruby","id":"CVE-2022-1212","kev_date_added":null,"published":"2022-04-05"},{"cvss_score":9.1,"headline":"NULL Pointer Dereference in mruby/mruby","id":"CVE-2021-4110","kev_date_added":null,"published":"2021-12-15"},{"cvss_score":8.4,"headline":"Out-of-bounds Read in mrb_get_args in mruby/mruby","id":"CVE-2022-1276","kev_date_added":null,"published":"2022-04-10"}],"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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-05-22","vendors":["mruby"]},"summary":"Attackers can exploit a heap-based buffer overflow in mruby to execute arbitrary code or cause denial of service.","url":"https://insights.sbomify.com/CVE-2022-0080/"}
