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-2023-48704 in the wild and no public exploit code.\n\nAffected product: ClickHouse. 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-2023-48704/ (Markdown: https://insights.sbomify.com/CVE-2023-48704/index.md)","id":"CVE-2023-48704","markdown":"https://insights.sbomify.com/CVE-2023-48704/index.md","name":"CVE-2023-48704","record":{"aliases":["GHSA-5rmf-5g48-xv63","UBUNTU-CVE-2023-48704"],"analysis":{"component_type":"database","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"ClickHouse database","requires_auth":"none","summary":"Unauthenticated attackers can crash the ClickHouse server via a heap buffer overflow in the Gorilla codec decompression logic.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"clickhouse","vendor":"clickhouse"},{"product":"clickhouse_cloud","vendor":"clickhouse"}],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-122","name":"Heap-based Buffer Overflow"},{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"ClickHouse is an open-source column-oriented database management system that allows generating analytical data reports in real-time.
