Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-4818 in the wild and no public exploit code.\n\nAffected product: floragunn Search Guard FLX. 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-2026-4818/ (Markdown: https://insights.sbomify.com/CVE-2026-4818/index.md)","id":"CVE-2026-4818","markdown":"https://insights.sbomify.com/CVE-2026-4818/index.md","name":"CVE-2026-4818","record":{"aliases":["GHSA-73g6-24f6-wqv9"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Search Guard FLX","requires_auth":"low_privilege","summary":"Users lacking necessary privileges can execute management operations on data streams, potentially leading to unauthorized data modification or privilege escalation.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"floragunn","cpe":[{"product":"flx","vendor":"search-guard"}],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"},{"id":"CWE-285","name":"Improper Authorization"}],"description":"In Search Guard FLX versions from 3.0.0 up to 4.0.1, there exists an issue which allows users without the necessary privileges to execute some management operations against data streams.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Some management operations on data streams are not properly restricted when user does not have the necessary privileges","id":"CVE-2026-4818","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Search Guard audit logs can contain under certain conditions user credentials","id":"CVE-2026-4819"},"packages":[],"prev":{"headline":"SQL injection in MasterStudy LMS WordPress Plugin – for Online Courses and Education","id":"CVE-2026-4817"},"products":["Search Guard FLX"],"published":"2026-03-31","related":[{"cvss_score":4.9,"headline":"Search Guard audit logs can contain under certain conditions user credentials","id":"CVE-2026-4819","kev_date_added":null,"published":"2026-03-31"},{"cvss_score":4.3,"headline":"Open redirect vulnerability in Search Guard Kibana Plugin via manipulated requests","id":"CVE-2026-4799","kev_date_added":null,"published":"2026-03-31"}],"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":"total"},"state":"PUBLISHED","updated":"2026-03-31","vendors":["floragunn"]},"summary":"Users lacking necessary privileges can execute management operations on data streams, potentially leading to unauthorized data modification or privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-4818/"}
