An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-21719 in the wild and no public exploit code.\n\nAffected product: CubeCart. 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-2026-21719/ (Markdown: https://insights.sbomify.com/CVE-2026-21719/index.md)","id":"CVE-2026-21719","markdown":"https://insights.sbomify.com/CVE-2026-21719/index.md","name":"CVE-2026-21719","record":{"aliases":["GHSA-mj52-hprj-j8xh"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"CubeCart e-commerce","requires_auth":"high_privilege","summary":"Administrative users can execute arbitrary OS commands via an injection flaw in CubeCart, requiring an upgrade to mitigate.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"cubecart","vendor":"cubecart"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"An OS command injection vulnerability exists in CubeCart prior to 6.6.0, which may allow a user with an administrative privilege to execute an arbitrary OS command.","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":"Command injection in CubeCart","id":"CVE-2026-21719","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Unauthenticated DoS: avatar cache leaks goroutines when /avatar/:hash requests time out","id":"CVE-2026-21720"},"packages":[],"prev":{"headline":"Copeland XWEB and XWEB Pro Use of a Broken or Risky Cryptographic Algorithm","id":"CVE-2026-21718"},"products":["CubeCart"],"published":"2026-04-17","related":[{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2024-34832","kev_date_added":null,"published":"2024-06-06"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2018-20716","kev_date_added":null,"published":"2019-01-15"},{"cvss_score":9.8,"headline":"Deserialization in n/a","id":"CVE-2013-1465","kev_date_added":null,"published":"2013-02-08"},{"cvss_score":8.1,"headline":"Cross-site request forgery in CubeCart","id":"CVE-2023-38130","kev_date_added":null,"published":"2023-11-17"},{"cvss_score":8,"headline":"File upload in n/a","id":"CVE-2024-33438","kev_date_added":null,"published":"2024-04-29"},{"cvss_score":7.5,"headline":"SQL injection in n/a","id":"CVE-2010-4903","kev_date_added":null,"published":"2011-10-08"}],"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":"2026-04-17","vendors":["CubeCart Limited"]},"summary":"Administrative users can execute arbitrary OS commands via an injection flaw in CubeCart, requiring an upgrade to mitigate.","url":"https://insights.sbomify.com/CVE-2026-21719/"}
