It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-18954 in the wild and no public exploit code.\n\nAffected product: AWS documentdb-mcp-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-2026-18954/ (Markdown: https://insights.sbomify.com/CVE-2026-18954/index.md)","id":"CVE-2026-18954","markdown":"https://insights.sbomify.com/CVE-2026-18954/index.md","name":"CVE-2026-18954","record":{"aliases":["GHSA-j694-4m5j-w8hc","GHSA-w95p-h69m-853r"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"DocumentDB MCP Server","requires_auth":"low_privilege","summary":"Authenticated clients can bypass read-only restrictions to perform unauthorized write operations on the database via aggregation pipelines.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMZN","cpe":[{"product":"documentdb_mcp_server","vendor":"amazon"}],"cvss":{"score":5.7,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Incorrect authorization in the aggregation pipeline tool in Amazon AWS Labs DocumentDB MCP Server before 1.0.12 might allow an authenticated MCP client to perform inappropriate write operations on the connected database via write-capable aggregation pipeline stages that bypass the read-only mode enforcement logic.\n\nTo remediate this issue, users should upgrade to version 1.0.12 or later.","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":"Incorrect authorization in the aggregation pipeline tool in Amazon AWS Labs DocumentDB MCP Server","id":"CVE-2026-18954","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Stored XSS in Menulux Software's Menulux Portal","id":"CVE-2026-18957"},"packages":[],"prev":{"headline":"Improper limitation of a pathname to a restricted directory in aws-transform-mcp-server","id":"CVE-2026-18953"},"products":["documentdb-mcp-server"],"published":"2026-08-05","related":[],"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":"2026-08-06","vendors":["AWS"]},"summary":"Authenticated clients can bypass read-only restrictions to perform unauthorized write operations on the database via aggregation pipelines.","url":"https://insights.sbomify.com/CVE-2026-18954/"}
