Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-9748 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mongodb (Bitnami): affected from 7.0.0; fixed in 7.0.35, 8.0.10, 8.2.10, 8.3.3\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-2026-9748/ (Markdown: https://insights.sbomify.com/CVE-2026-9748/index.md)","id":"CVE-2026-9748","markdown":"https://insights.sbomify.com/CVE-2026-9748/index.md","name":"CVE-2026-9748","record":{"aliases":["BIT-mongodb-2026-9748","GHSA-7r4j-g3f5-3629","MINI-882v-6wc2-vffw","MINI-f74v-9mpx-j27j","MINI-h9g7-rgrj-gvm8","MINI-hwp5-fq4q-wq75","UBUNTU-CVE-2026-9748"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"MongoDB Server","requires_auth":"low_privilege","summary":"A crafted aggregation pipeline can crash the MongoDB server by triggering an assertion failure in the TeeBuffer component.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mongodb","cpe":[{"product":"mongodb","vendor":"mongodb"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-617","name":"Reachable Assertion"}],"description":"The $_internalConvertBucketIndexStats stage used PauseExecution as a way to signal \"skip this document\" when an index stats conversion failed.
