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-2026-46752 in the wild and no public exploit code.\n\nAffected product: Apache Kvrocks. 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-2026-46752/ (Markdown: https://insights.sbomify.com/CVE-2026-46752/index.md)","id":"CVE-2026-46752","markdown":"https://insights.sbomify.com/CVE-2026-46752/index.md","name":"CVE-2026-46752","record":{"aliases":["GHSA-8g2g-w8wp-x78h","MINI-rx8x-8frh-5978"],"analysis":{"component_type":"database","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Kvrocks","requires_auth":"none","summary":"A stack buffer overflow in the Lua bit.tohex function allows attackers 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":"apache","cpe":[],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"Redis Lua HEAP overflow in cjson library vulnerability in Apache Kvrocks.\n\nThis issue affects Apache Kvrocks: from 2.0.4 through 2.15.0.\n\nUsers are recommended to upgrade to version 2.16.0, which fixes the issue.","ecosystems":[],"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":"Apache Kvrocks: Stack buffer overflow in Lua bit.tohex()","id":"CVE-2026-46752","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Apache Airflow: Event Log detail endpoint bypasses DAG-scoped event log permission filter","id":"CVE-2026-46764"},"packages":[],"prev":{"headline":"Denial of service in Apache Kvrocks","id":"CVE-2026-46751"},"products":["Apache Kvrocks"],"published":"2026-06-25","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-06-25","vendors":["Apache Software Foundation"]},"summary":"A stack buffer overflow in the Lua bit.tohex function allows attackers to execute arbitrary code or cause denial of service.","url":"https://insights.sbomify.com/CVE-2026-46752/"}
