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-2021-47908 exists.\n\nAffected product: thewebfosters Unknown. 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-2021-47908/ (Markdown: https://insights.sbomify.com/CVE-2021-47908/index.md)","id":"CVE-2021-47908","markdown":"https://insights.sbomify.com/CVE-2021-47908/index.md","name":"CVE-2021-47908","record":{"aliases":["GHSA-p8xp-337m-35c6"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Ultimate POS","requires_auth":"low_privilege","summary":"Remote attackers can inject malicious scripts via product names in Ultimate POS, potentially hijacking user sessions and executing arbitrary JavaScript.","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":"Ultimate POS 4.4 contains a persistent cross-site scripting vulnerability in the product name parameter that allows remote attackers to inject malicious scripts.
