Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-1428 in the wild and no public exploit code.\n\nAffected product: WellChoose Single Sign-On Portal System. 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-2026-1428/ (Markdown: https://insights.sbomify.com/CVE-2026-1428/index.md)","id":"CVE-2026-1428","markdown":"https://insights.sbomify.com/CVE-2026-1428/index.md","name":"CVE-2026-1428","record":{"aliases":["GHSA-673g-gvq6-jf92"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Single Sign-On Portal","requires_auth":"low_privilege","summary":"Authenticated attackers can inject arbitrary OS commands to execute code on the server hosting the WellChoose Single Sign-On Portal System.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"twcert","cpe":[{"product":"single_sign-on_portal_system","vendor":"wellchoose"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/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":"Single Sign-On Portal System developed by WellChoose has a OS Command Injection vulnerability, allowing authenticated remote attackers to inject arbitrary OS commands and execute them on the server.","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":"WellChoose｜Single Sign-On Portal System - OS Command Injection","id":"CVE-2026-1428","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":"WellChoose｜Single Sign-On Portal System - Reflected Cross-site Scripting","id":"CVE-2026-1429"},"packages":[],"prev":{"headline":"WellChoose｜Single Sign-On Portal System - OS Command Injection","id":"CVE-2026-1427"},"products":["Single Sign-On Portal System"],"published":"2026-01-26","related":[{"cvss_score":8.7,"headline":"WellChoose｜Single Sign-On Portal System - OS Command Injection","id":"CVE-2026-1427","kev_date_added":null,"published":"2026-01-26"},{"cvss_score":4.8,"headline":"WellChoose｜Single Sign-On Portal System - Reflected Cross-site Scripting","id":"CVE-2026-1429","kev_date_added":null,"published":"2026-01-26"}],"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":"2026-01-26","vendors":["WellChoose"]},"summary":"Authenticated attackers can inject arbitrary OS commands to execute code on the server hosting the WellChoose Single Sign-On Portal System.","url":"https://insights.sbomify.com/CVE-2026-1428/"}
