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-2024-21512 exists.\n\nAffected packages and fixed versions:\n- mysql2 (npm): affected all versions; fixed in 3.9.8\n- mysql2 (npm): affected all versions; fixed in 3.9.8\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-2024-21512/ (Markdown: https://insights.sbomify.com/CVE-2024-21512/index.md)","id":"CVE-2024-21512","markdown":"https://insights.sbomify.com/CVE-2024-21512/index.md","name":"CVE-2024-21512","record":{"aliases":["GHSA-pmh2-wpjm-fj45","ROOT-APP-NPM-CVE-2024-21512"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"MySQL client library","requires_auth":"none","summary":"Prototype pollution in mysql2 allows attackers to modify object prototypes when nestTables is enabled, potentially leading to application instability or logic errors.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:L/E:P","version":"3.1"},"cwes":[{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"Versions of the package mysql2 before 3.9.8 are vulnerable to Prototype Pollution due to improper user input sanitization passed to fields and tables when using nestTables.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"mysql2 vulnerable to Prototype Pollution","id":"CVE-2024-21512","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"other","year":"2024"},"n_packages":2,"n_references":5,"next":{"headline":"langchain-experimental vulnerable to Arbitrary Code Execution","id":"CVE-2024-21513"},"packages":[{"ecosystem":"npm","fixed":["3.9.8"],"introduced":["0"],"last_affected":[],"package":"mysql2","purl":null,"source":"GHSA-pmh2-wpjm-fj45"},{"ecosystem":"npm","fixed":["3.9.8"],"introduced":["0"],"last_affected":[],"package":"mysql2","purl":"pkg:npm/mysql2","source":"GHSA-pmh2-wpjm-fj45"}],"prev":{"headline":"MySQL2 for Node Arbitrary Code Injection","id":"CVE-2024-21511"},"products":["mysql2","org.webjars.npm:mysql2"],"published":"2024-05-29","related":[],"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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-08-01","vendors":["n/a"]},"summary":"Prototype pollution in mysql2 allows attackers to modify object prototypes when nestTables is enabled, potentially leading to application instability or logic errors.","url":"https://insights.sbomify.com/CVE-2024-21512/"}
