An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-4359 in the wild and no public exploit code.\n\nAffected product: MongoDB C Driver. 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-2026-4359/ (Markdown: https://insights.sbomify.com/CVE-2026-4359/index.md)","id":"CVE-2026-4359","markdown":"https://insights.sbomify.com/CVE-2026-4359/index.md","name":"CVE-2026-4359","record":{"aliases":["DEBIAN-CVE-2026-4359","GHSA-3548-98v9-6pq6","JLSEC-2026-182","OESA-2026-1742","OESA-2026-1743","OESA-2026-1744","OESA-2026-1746","OESA-2026-1747","UBUNTU-CVE-2026-4359"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"MongoDB C Driver","requires_auth":"high_privilege","summary":"A heap-buffer-over-read in the MongoDB C Driver allows attackers to cause application crashes via malformed HTTP responses.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mongodb","cpe":[{"product":"c_driver","vendor":"mongodb"}],"cvss":{"score":2,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:H/UI:P/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-158","name":"Improper Neutralization of Null Byte or NUL Character"}],"description":"A compromised third party cloud server or man-in-the-middle attacker could send a malformed HTTP response and cause a crash in applications using the MongoDB C driver.","ecosystems":[],"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":"Heap-buffer-over-read in _mongoc_http_send via strstr on non-null-terminated buffer","id":"CVE-2026-4359","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Tarfile.extract() doesn't fully respect filter parameter","id":"CVE-2026-4360"},"packages":[],"prev":{"headline":"Memory safety issues in slot-based execution hash table spill","id":"CVE-2026-4358"},"products":["MongoDB C Driver"],"published":"2026-03-17","related":[{"cvss_score":9.2,"headline":"Heap overflow via oversized decrypted TLS record sequence in Windows Secure Channel stream","id":"CVE-2026-93393","kev_date_added":null,"published":"2026-09-17"},{"cvss_score":8.6,"headline":"MongoDB C Driver Cyrus SASL Canonicalization Buffer Overflow","id":"CVE-2026-6691","kev_date_added":null,"published":"2026-05-06"},{"cvss_score":8.2,"headline":"Heap corruption via OCSP request double free from crafted multi-URL certificate in TLS client","id":"CVE-2026-84964","kev_date_added":null,"published":"2026-09-03"},{"cvss_score":7.3,"headline":"Accessing Untrusted Directory May Allow Local Privilege Escalation","id":"CVE-2024-7553","kev_date_added":null,"published":"2024-08-07"},{"cvss_score":6.9,"headline":"Integer Underflow → Heap Out-of-Bounds Read in `bson_new_from_buffer()","id":"CVE-2026-93395","kev_date_added":null,"published":"2026-09-17"},{"cvss_score":6.9,"headline":"Bulk write with options may read invalid memory","id":"CVE-2025-12119","kev_date_added":null,"published":"2025-11-18"},{"cvss_score":6.3,"headline":"libmongoc SCRAM client nonce-validation bypass","id":"CVE-2026-93394","kev_date_added":null,"published":"2026-09-17"}],"sources":[{"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":"2026-03-18","vendors":["MongoDB Inc"]},"summary":"A heap-buffer-over-read in the MongoDB C Driver allows attackers to cause application crashes via malformed HTTP responses.","url":"https://insights.sbomify.com/CVE-2026-4359/"}
