Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-103965 in the wild and no public exploit code.\n\nAffected product: MongoDB Server. 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-2026-103965/ (Markdown: https://insights.sbomify.com/CVE-2026-103965/index.md)","id":"CVE-2026-103965","markdown":"https://insights.sbomify.com/CVE-2026-103965/index.md","name":"CVE-2026-103965","record":{"aliases":["GHSA-8w3x-ww8f-273q","UBUNTU-CVE-2026-103965"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"MongoDB Server","requires_auth":"low_privilege","summary":"Authenticated users with read access may inadvertently view unintended field values due to incorrect handling of constant values in aggregation queries.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mongodb","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"An issue in MongoDB Server's aggregation framework can cause certain constant values to be handled incorrectly during internal query rewriting.
