Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-47856 exists.\n\nAffected product: NetArt Media Easy Cart Shopping Cart. 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-2021-47856/ (Markdown: https://insights.sbomify.com/CVE-2021-47856/index.md)","id":"CVE-2021-47856","markdown":"https://insights.sbomify.com/CVE-2021-47856/index.md","name":"CVE-2021-47856","record":{"aliases":["GHSA-rwxf-95vh-qm4r"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Shopping cart software","requires_auth":"low_privilege","summary":"Remote attackers can inject malicious scripts via the search parameter to compromise user sessions and manipulate content in Easy Cart Shopping Cart.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Easy Cart Shopping Cart 2021 contains a non-persistent cross-site scripting vulnerability in the search module's keyword parameter.
