Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-22946 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.spark:spark-core_2.12 (Maven): affected all versions; fixed in 3.3.3\n- org.apache.spark:spark-core_2.12 (Maven): affected all versions; fixed in 3.3.3\n- spark (Bitnami): affected all versions; fixed in 3.4.0\n- org.apache.spark:spark-core_2.13 (Maven): affected all versions; fixed in 3.3.3\n- org.apache.spark:spark-core_2.13 (Maven): affected all versions; fixed in 3.3.3\n- pyspark (PyPI): affected all versions; fixed in 3.3.2\n- pyspark (PyPI): affected all versions; fixed in 3.3.2\n- pyspark (PyPI): affected all versions; fixed in 3.4.0\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-2023-22946/ (Markdown: https://insights.sbomify.com/CVE-2023-22946/index.md)","id":"CVE-2023-22946","markdown":"https://insights.sbomify.com/CVE-2023-22946/index.md","name":"CVE-2023-22946","record":{"aliases":["BIT-spark-2023-22946","GHSA-329j-jfvr-rhr6","PYSEC-2023-44"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache Spark","requires_auth":"low_privilege","summary":"Attackers can escalate privileges and execute code as the submitting user by providing malicious configuration classes in Apache Spark applications using proxy-user.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"spark","vendor":"apache"}],"cvss":{"score":6.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"In Apache Spark versions prior to 3.4.0, applications using spark-submit can specify a 'proxy-user' to run as, limiting privileges.
