Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-4358 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mongodb (Bitnami): affected from 7.0.0; fixed in 7.0.31, 8.0.20, 8.2.6\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-2026-4358/ (Markdown: https://insights.sbomify.com/CVE-2026-4358/index.md)","id":"CVE-2026-4358","markdown":"https://insights.sbomify.com/CVE-2026-4358/index.md","name":"CVE-2026-4358","record":{"aliases":["BIT-mongodb-2026-4358","GHSA-64ph-qr47-qxh4","MINI-8gxc-g5pp-86qc","MINI-p4h5-hp62-chcj","UBUNTU-CVE-2026-4358"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"MongoDB Server","requires_auth":"low_privilege","summary":"An authenticated user with write privileges can trigger a use-after-free or double-free in MongoDB's SBE engine via a crafted aggregation query, potentially leading to code execution or denial of service.","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:N/PR:L/UI:N/VC:L/VI:L/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-415","name":"Double Free"}],"description":"A specially crafted aggregation query with $lookup by an authenticated user with write privileges can cause a double-free or use-after-free memory issue in the slot-based execution (SBE) engine when an in-memory hash table is spilled to disk.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Memory safety issues in slot-based execution hash table spill","id":"CVE-2026-4358","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"mongodb:mongodb","products":["mongodb:mongodb"],"type":"use_after_free","year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"Heap-buffer-over-read in _mongoc_http_send via strstr on non-null-terminated buffer","id":"CVE-2026-4359"},"packages":[{"ecosystem":"Bitnami","fixed":["7.0.31","8.0.20","8.2.6"],"introduced":["7.0.0","8.0.0","8.2.0"],"last_affected":[],"package":"mongodb","purl":"pkg:bitnami/mongodb","source":"BIT-mongodb-2026-4358"}],"prev":{"headline":"Embed HTML5 Game \u003c= 1.3 - Unauthenticated Arbitrary File Upload","id":"CVE-2026-4357"},"products":["MongoDB Server"],"published":"2026-03-17","related":[{"cvss_score":8.7,"headline":"MongoDB and MongoDB Server Improper Handling of Length Parameter Inconsistency","id":"CVE-2025-14847","kev_date_added":"2025-12-29","published":"2025-12-19"},{"cvss_score":9.2,"headline":"Auth bypass in MongoDB Server","id":"CVE-2026-82067","kev_date_added":null,"published":"2026-09-08"},{"cvss_score":9.2,"headline":"MongoDB Improper Input Validation in Compute Mode External Data Processing Leading to Memory Corruption","id":"CVE-2026-13072","kev_date_added":null,"published":"2026-07-22"},{"cvss_score":9.1,"headline":"Denial of service in n/a","id":"CVE-2017-15535","kev_date_added":null,"published":"2017-11-01"},{"cvss_score":9,"headline":"Improper Authentication in MongoDB Intra-Cluster Connections Allows Credential Exposure","id":"CVE-2026-18691","kev_date_added":null,"published":"2026-08-11"},{"cvss_score":8.8,"headline":"MongoDB Server may allow successful untrusted connection","id":"CVE-2024-1351","kev_date_added":null,"published":"2024-03-07"},{"cvss_score":8.7,"headline":"Denial of service in MongoDB Server","id":"CVE-2026-82064","kev_date_added":null,"published":"2026-09-08"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-03-17","vendors":["MongoDB Inc"]},"summary":"An authenticated user with write privileges can trigger a use-after-free or double-free in MongoDB's SBE engine via a crafted aggregation query, potentially leading to code execution or denial of service.","url":"https://insights.sbomify.com/CVE-2026-4358/"}
