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-2021-20333 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mongodb (Bitnami): affected from 3.6.0; fixed in 3.6.20, 4.0.21, 4.2.10\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-2021-20333/ (Markdown: https://insights.sbomify.com/CVE-2021-20333/index.md)","id":"CVE-2021-20333","markdown":"https://insights.sbomify.com/CVE-2021-20333/index.md","name":"CVE-2021-20333","record":{"aliases":["BIT-mongodb-2021-20333","GHSA-ghvr-mww9-3hrg","UBUNTU-CVE-2021-20333"],"analysis":{"component_type":"database","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"MongoDB Server","requires_auth":"none","summary":"Attackers can spoof or split server log entries by sending crafted commands, compromising audit integrity in MongoDB Server.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mongodb","cpe":[{"product":"mongodb","vendor":"mongodb"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-116","name":"Improper Encoding or Escaping of Output"},{"id":"CWE-117","name":"Improper Output Neutralization for Logs"}],"description":"Sending specially crafted commands to a MongoDB Server may result in artificial log entries being generated or for log entries to be split.
