Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-81533 in the wild and no public exploit code.\n\nAffected product: MongoDB BI Connector ODBC Driver. 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-2026-81533/ (Markdown: https://insights.sbomify.com/CVE-2026-81533/index.md)","id":"CVE-2026-81533","markdown":"https://insights.sbomify.com/CVE-2026-81533/index.md","name":"CVE-2026-81533","record":{"aliases":["GHSA-gj6m-p8hr-868g"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"MongoDB BI Connector","requires_auth":"low_privilege","summary":"An attacker can cause memory corruption or denial of service in applications using the MongoDB BI Connector ODBC Driver by submitting oversized LIMIT values when prefetch is enabled.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mongodb","cpe":[{"product":"bi_connector_odbc_driver","vendor":"mongodb"}],"cvss":{"score":6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"An application using the MongoDB BI Connector ODBC Driver may encounter a memory-safety issue when a submitted SQL statement contains an unusually long run of digits following a LIMIT clause.
