An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-21643 in the wild since at least 13 Apr 2026.\n\nAffected product: Fortinet FortiClientEMS. 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-2026-21643/ (Markdown: https://insights.sbomify.com/CVE-2026-21643/index.md)","id":"CVE-2026-21643","markdown":"https://insights.sbomify.com/CVE-2026-21643/index.md","name":"CVE-2026-21643","record":{"aliases":["GHSA-r6vr-hwpr-qqch"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"FortiClient EMS","requires_auth":"none","summary":"Unauthenticated attackers can execute unauthorized code via SQL injection in FortiClient EMS, requiring immediate patching.","user_interaction":"not_required","vuln_class":"sql_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fortinet","cpe":[{"product":"forticlientems","vendor":"fortinet"}],"cvss":{"score":9.1,"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-89","name":"Improper Neutralization of Special Elements used in an SQL Command"}],"description":"An improper neutralization of special elements used in an sql command ('sql injection') vulnerability in Fortinet FortiClientEMS 7.4.4 may allow an unauthenticated attacker to execute unauthorized code or commands via specifically crafted HTTP requests.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-03-27","github_poc":2,"max_poc_stars":18,"metasploit":0,"nuclei":1,"refs":[{"date":"2026-03-28T19:09:38Z","kind":"github_poc","ref":"https://github.com/0xredash/CVE-2026-21643","stars":18,"title":"CVE-2026-21643"},{"date":"2026-03-27T19:11:15Z","kind":"github_poc","ref":"https://github.com/alirezac0/CVE-2026-21643","stars":5,"title":"Python PoC and Nuclei template for CVE-2026-21643 (Pre-Authentication SQL Injection in FortiClient EMS 7.4.4)"},{"date":null,"kind":"nuclei","ref":"http/cves/2026/CVE-2026-21643.yaml","stars":null,"title":"Fortinet FortiClientEMS 7.4.4 - SQL Injection"}],"tier":"exploited"},"has_fix":null,"headline":"Fortinet FortiClient EMS SQL Injection","id":"CVE-2026-21643","indexable":true,"kev":{"dateAdded":"2026-04-13","dueDate":"2026-04-16","knownRansomwareCampaignUse":"Unknown","product":"FortiClient EMS","requiredAction":"Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.","vendorProject":"Fortinet","vulnerabilityName":"Fortinet FortiClient EMS SQL Injection Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"sql_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Not used","id":"CVE-2026-21644"},"packages":[],"prev":{"headline":"Cross-site scripting in Revive Adserver","id":"CVE-2026-21642"},"products":["FortiClientEMS"],"published":"2026-02-06","related":[{"cvss_score":9.1,"headline":"Fortinet FortiClient EMS Improper Access Control","id":"CVE-2026-35616","kev_date_added":"2026-04-06","published":"2026-04-04"},{"cvss_score":7.7,"headline":"Auth bypass in FortiClientEMS","id":"CVE-2024-23106","kev_date_added":null,"published":"2025-01-14"},{"cvss_score":6.8,"headline":"SQL injection in FortiClientEMS","id":"CVE-2025-59922","kev_date_added":null,"published":"2026-01-13"},{"cvss_score":6.7,"headline":"Security feature bypass in FortiClientEMS","id":"CVE-2026-59836","kev_date_added":null,"published":"2026-07-14"},{"cvss_score":6.2,"headline":"SQL injection in FortiClientEMS","id":"CVE-2026-39809","kev_date_added":null,"published":"2026-04-14"},{"cvss_score":5.4,"headline":"Cross-site scripting in FortiClientEMS","id":"CVE-2019-16149","kev_date_added":null,"published":"2025-03-28"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-04-14","vendors":["Fortinet"]},"summary":"Unauthenticated attackers can execute unauthorized code via SQL injection in FortiClient EMS, requiring immediate patching.","url":"https://insights.sbomify.com/CVE-2026-21643/"}
