Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-96297 in the wild and no public exploit code.\n\nAffected product: MongoDB Server. 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-2026-96297/ (Markdown: https://insights.sbomify.com/CVE-2026-96297/index.md)","id":"CVE-2026-96297","markdown":"https://insights.sbomify.com/CVE-2026-96297/index.md","name":"CVE-2026-96297","record":{"aliases":["GHSA-8hjj-9fm5-xw5g","UBUNTU-CVE-2026-96297"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"MongoDB Server","requires_auth":"low_privilege","summary":"An authenticated user can trigger a use-after-free in MongoDB Server to read unrelated process memory or cause a crash via crafted aggregation pipelines.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mongodb","cpe":[],"cvss":{"score":6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Use of freed memory in the aggregation feature of MongoDB Server can cause the server to read data from a memory area after it has been released. When an internal aggregation stage is combined with a batch size of 0, the server may read from memory that is no longer in use. Because that memory can be reused for other data before it is read, query results returned to the client may contain unrelated data from the server process. Depending on the state of memory at the time, the server process may also terminate unexpectedly. The behavior can occur when an authenticated user with read privileges runs an aggregate command that combines these two settings.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"MongoDB Server may disclose process memory via a crafted `$_internalApplyOplogUpdate` aggregation pipeline","id":"CVE-2026-96297","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Missing Authorization Check on Internal Aggregation Stage in MongoDB Server mongos Leads to Denial of Service","id":"CVE-2026-96299"},"packages":[],"prev":{"headline":"Apache Thrift: nodejs web server: no `error` listener on an upgraded WebSocket connection","id":"CVE-2026-96294"},"products":["MongoDB Server"],"published":"2026-10-13","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-10-13","vendors":["MongoDB"]},"summary":"An authenticated user can trigger a use-after-free in MongoDB Server to read unrelated process memory or cause a crash via crafted aggregation pipelines.","url":"https://insights.sbomify.com/CVE-2026-96297/"}
