An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-40821 in the wild and no public exploit code.\n\nAffected product: Helmholz mbCONNECT24. 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-2026-40821/ (Markdown: https://insights.sbomify.com/CVE-2026-40821/index.md)","id":"CVE-2026-40821","markdown":"https://insights.sbomify.com/CVE-2026-40821/index.md","name":"CVE-2026-40821","record":{"aliases":["GHSA-vr4v-549x-p6j7"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"IoT connectivity platform","requires_auth":"high_privilege","summary":"A remote attacker can exploit SQL injection in the getAccountByID function to read sensitive data from the database.","user_interaction":"not_required","vuln_class":"sql_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-89","name":"Improper Neutralization of Special Elements used in an SQL Command"}],"description":"A high privileged remote attacker can exploit an unauthenticated SQL Injection vulnerability in the getAccountByID function due to improper neutralization of special elements in a SQL SELECT command.
