Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-18695 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mongodb (Bitnami): affected from 7.0.0; fixed in 7.0.40, 8.0.29, 8.3.8, 9.0.2\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-2026-18695/ (Markdown: https://insights.sbomify.com/CVE-2026-18695/index.md)","id":"CVE-2026-18695","markdown":"https://insights.sbomify.com/CVE-2026-18695/index.md","name":"CVE-2026-18695","record":{"aliases":["BIT-mongodb-2026-18695","GHSA-7xvj-42gq-cx6p","MINI-2wpg-fj9w-f8wx","MINI-52jf-fq4f-cpjr","MINI-95w4-hx87-hw8g","MINI-wwpc-wf25-hf7r","UBUNTU-CVE-2026-18695"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"MongoDB Server","requires_auth":"low_privilege","summary":"An authenticated user with write access can cause MongoDB Server to crash by sending specific queries to time-series collections, resulting in denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mongodb","cpe":[{"product":"mongodb","vendor":"mongodb"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-617","name":"Reachable Assertion"}],"description":"An issue in MongoDB Server's handling of certain query predicates against time-series collections with a metaField could allow an authenticated user with write access to cause the server process to terminate unexpectedly, resulting in a denial of service.","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":"Improper Input Validation in MongoDB Timeseries Query Processing Leads to Denial of Service","id":"CVE-2026-18695","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"mongodb:mongodb","products":["mongodb:mongodb"],"type":"denial_of_service","year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"Improper Authorization in MongoDB applyOps Command Handling Allows Unauthorized DDL Operations on Collections","id":"CVE-2026-18696"},"packages":[{"ecosystem":"Bitnami","fixed":["7.0.40","8.0.29","8.3.8","9.0.2"],"introduced":["7.0.0","8.0.0","8.2.0","9.0.0"],"last_affected":[],"package":"mongodb","purl":"pkg:bitnami/mongodb","source":"BIT-mongodb-2026-18695"}],"prev":{"headline":"Out-of-Bounds Read in MongoDB Geospatial Query Processing Leads to Denial of Service and Potential Memory Disclosure","id":"CVE-2026-18694"},"products":["MongoDB Server"],"published":"2026-08-11","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":"2026-08-11","vendors":["MongoDB"]},"summary":"An authenticated user with write access can cause MongoDB Server to crash by sending specific queries to time-series collections, resulting in denial of service.","url":"https://insights.sbomify.com/CVE-2026-18695/"}
