An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-84390 in the wild and no public exploit code.\n\nAffected product: Fortinet FortiMonitorOnSight. 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-2026-84390/ (Markdown: https://insights.sbomify.com/CVE-2026-84390/index.md)","id":"CVE-2026-84390","markdown":"https://insights.sbomify.com/CVE-2026-84390/index.md","name":"CVE-2026-84390","record":{"aliases":["GHSA-g584-wqjw-m2r8"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Fortinet monitoring software","requires_auth":"none","summary":"An attacker can access sensitive information included in the source code of FortiMonitorOnSight, leading to potential data exposure.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fortinet","cpe":[],"cvss":{"score":9.6,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:F/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-540","name":"Inclusion of Sensitive Information in Source Code"}],"description":"A inclusion of sensitive information in source code vulnerability in Fortinet FortiMonitorOnSight 7.2.4 through 7.2.7, FortiMonitorOnSight 7.2.0 through 7.2.2 may allow attacker to improper access control via \u003cinsert attack vector here\u003e","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":"Information disclosure in FortiMonitorOnSight","id":"CVE-2026-84390","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in FortiAnalyzer","id":"CVE-2026-84391"},"packages":[],"prev":{"headline":"Open redirect in FortiSIEM","id":"CVE-2026-84389"},"products":["FortiMonitorOnSight"],"published":"2026-09-11","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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-11","vendors":["Fortinet"]},"summary":"An attacker can access sensitive information included in the source code of FortiMonitorOnSight, leading to potential data exposure.","url":"https://insights.sbomify.com/CVE-2026-84390/"}
