Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-3821 in the wild and no public exploit code.\n\nAffected product: SMCI X14DBG-DAP,X14DBI. 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-2026-3821/ (Markdown: https://insights.sbomify.com/CVE-2026-3821/index.md)","id":"CVE-2026-3821","markdown":"https://insights.sbomify.com/CVE-2026-3821/index.md","name":"CVE-2026-3821","record":{"aliases":["GHSA-cjff-5v28-x7h8"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Supermicro BMC firmware","requires_auth":"low_privilege","summary":"An authorized attacker can exploit SMASH input to execute arbitrary code or cause denial of service on Supermicro BMCs.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Supermicro","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"Supermicro (SMC) SMASH services contain an Arbitrary code execution issue in X14DBG-DAP and X14DBI.\nAn authorized attacker can exploit SMASH’s input capability to compromise data integrity or launch a Denial-of-Service (DoS) attack against the BMC.","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":"Supermicro SMASH service contain an Arbitrary code execution issue","id":"CVE-2026-3821","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Taipower｜Taipower APP(Android) - Improper Certificate Validation","id":"CVE-2026-3822"},"packages":[],"prev":{"headline":"Supermicro BMC's SMTP service contains a command injection vulnerability","id":"CVE-2026-3820"},"products":["X14DBG-DAP,X14DBI"],"published":"2026-07-22","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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-22","vendors":["SMCI"]},"summary":"An authorized attacker can exploit SMASH input to execute arbitrary code or cause denial of service on Supermicro BMCs.","url":"https://insights.sbomify.com/CVE-2026-3821/"}
