Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-8201 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mongodb (Bitnami): affected from 7.0.0; fixed in 7.0.34, 8.0.23, 8.2.9, 8.3.2\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-2026-8201/ (Markdown: https://insights.sbomify.com/CVE-2026-8201/index.md)","id":"CVE-2026-8201","markdown":"https://insights.sbomify.com/CVE-2026-8201/index.md","name":"CVE-2026-8201","record":{"aliases":["BIT-mongodb-2026-8201","GHSA-r8cx-9wfm-r3m7","MINI-3w5q-r3cx-g6q6","MINI-66hc-cpjp-9959","MINI-f687-p474-978q","UBUNTU-CVE-2026-8201"],"analysis":{"component_type":"database","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"MongoDB Server","requires_auth":"low_privilege","summary":"Attackers can trigger a use-after-free in MongoDB's FLE query analysis by crafting specific encrypted field queries, potentially leading to code execution or crashes.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mongodb","cpe":[{"product":"mongodb","vendor":"mongodb"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:L/VI:L/VA:H/SC:L/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"A use-after-free vulnerability exists in MongoDB's Field-Level Encryption (FLE) query analysis component, affecting client-side uses of mongocryptd and crypt_shared.
