It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-46666 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mariadb (Bitnami): affected all versions; fixed in 10.2.39, 10.3.30, 10.4.20, 10.5.11, 10.6.2\n- mariadb-min (Bitnami): affected all versions; fixed in 10.2.39, 10.3.30, 10.4.20, 10.5.11, 10.6.2\n- mysql-client (Bitnami): affected all versions; fixed in 10.2.39, 10.3.30, 10.4.20, 10.5.11, 10.6.2\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-2021-46666/ (Markdown: https://insights.sbomify.com/CVE-2021-46666/index.md)","id":"CVE-2021-46666","markdown":"https://insights.sbomify.com/CVE-2021-46666/index.md","name":"CVE-2021-46666","record":{"aliases":["AZL-8410","BIT-mariadb-2021-46666","BIT-mariadb-min-2021-46666","BIT-mysql-client-2021-46666","DEBIAN-CVE-2021-46666","GHSA-qhvg-j82m-w264","UBUNTU-CVE-2021-46666"],"analysis":{"component_type":"database","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"MariaDB database","requires_auth":"low_privilege","summary":"An attacker can cause a MariaDB application crash by exploiting mishandled query pushdown logic, requiring an upgrade to restore service availability.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mariadb","vendor":"mariadb"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-617","name":"Reachable Assertion"}],"description":"MariaDB before 10.6.2 allows an application crash because of mishandling of a pushdown from a HAVING clause to a WHERE clause.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Denial of service in n/a","id":"CVE-2021-46666","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"mariadb:mariadb","products":["mariadb:mariadb"],"type":"denial_of_service","year":"2021"},"n_packages":3,"n_references":3,"next":{"headline":"Integer overflow in n/a","id":"CVE-2021-46667"},"packages":[{"ecosystem":"Bitnami","fixed":["10.2.39","10.3.30","10.4.20","10.5.11","10.6.2"],"introduced":["0","10.3.0","10.4.0","10.5.0","10.6.0"],"last_affected":[],"package":"mariadb","purl":"pkg:bitnami/mariadb","source":"BIT-mariadb-2021-46666"},{"ecosystem":"Bitnami","fixed":["10.2.39","10.3.30","10.4.20","10.5.11","10.6.2"],"introduced":["0","10.3.0","10.4.0","10.5.0","10.6.0"],"last_affected":[],"package":"mariadb-min","purl":"pkg:bitnami/mariadb-min","source":"BIT-mariadb-min-2021-46666"},{"ecosystem":"Bitnami","fixed":["10.2.39","10.3.30","10.4.20","10.5.11","10.6.2"],"introduced":["0","10.3.0","10.4.0","10.5.0","10.6.0"],"last_affected":[],"package":"mysql-client","purl":"pkg:bitnami/mysql-client","source":"BIT-mysql-client-2021-46666"}],"prev":{"headline":"Denial of service in n/a","id":"CVE-2021-46665"},"products":["n/a"],"published":"2022-02-01","related":[{"cvss_score":10,"headline":"MariaDB server has unsafe parameter handling in `wsrep_notify_cmd`","id":"CVE-2026-49261","kev_date_added":null,"published":"2026-06-11"},{"cvss_score":9.9,"headline":"MariaDB: Out-of-bound buffer write on in `ST_AsText` of nested GeometryCollections","id":"CVE-2026-85746","kev_date_added":null,"published":"2026-10-16"},{"cvss_score":9.9,"headline":"MariaDB: Use-after-free with a large number of SYS_REFCURSOR's","id":"CVE-2026-85748","kev_date_added":null,"published":"2026-10-16"},{"cvss_score":9.9,"headline":"MariaDB: Numerous issues caused by historical #mysql50# tablename encoding bypass.","id":"CVE-2026-92262","kev_date_added":null,"published":"2026-10-16"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2023-26785","kev_date_added":null,"published":"2024-10-17"},{"cvss_score":8.8,"headline":"MariaDB: GRANT PROXY with empty password incorrectly checks grantor's privileges","id":"CVE-2026-97380","kev_date_added":null,"published":"2026-10-16"},{"cvss_score":8.6,"headline":"Heap-based Buffer Overflow in MariaDB","id":"CVE-2026-32710","kev_date_added":null,"published":"2026-03-20"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"An attacker can cause a MariaDB application crash by exploiting mishandled query pushdown logic, requiring an upgrade to restore service availability.","url":"https://insights.sbomify.com/CVE-2021-46666/"}
