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-2026-126148 in the wild and no public exploit code.\nExposure: Only installations with a non-default setting turned on are exposed.\n\nAffected product: Fortinet FortiMail. 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-2026-126148/ (Markdown: https://insights.sbomify.com/CVE-2026-126148/index.md)","id":"CVE-2026-126148","markdown":"https://insights.sbomify.com/CVE-2026-126148/index.md","name":"CVE-2026-126148","record":{"aliases":["GHSA-94pv-xwr4-33w5"],"analysis":{"component_type":"server_software","exploitable_when_present":false,"fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"email security gateway","requires_auth":"none","requires_specific_call":false,"summary":"Unauthenticated attackers can execute commands on FortiMail via crafted HA join-request packets; FortiMail administrators should care.","user_interaction":"not_required","vuln_class":"command_injection","vulnerable_functions":[]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"fortinet","cpe":[],"cvss":{"score":9.8,"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:P/RL:O/RC:R","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"A improper neutralization of special elements used in an os command ('os command injection') vulnerability in Fortinet FortiMail 8.0.0 through 8.0.1, FortiMail 7.6.0 through 7.6.6 may allow an unauthenticated attacker to execute unauthorized code or commands via crafted HA join-request packets.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-11-12","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-11-12T03:41:26Z","kind":"github_poc","ref":"https://github.com/googlesky/CVE-2026-126148","stars":0,"title":"Containerised PoC for CVE-2026-126148 (Fortinet FG-IR-26-200): an OS command injection (CWE-78) in the FortiMail HA cluster lets one unauthenticated join-request packet reach command execution as root.
