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-2021-47917 exists.\n\nAffected product: Simplephpscripts Simple CMS. 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-2021-47917/ (Markdown: https://insights.sbomify.com/CVE-2021-47917/index.md)","id":"CVE-2021-47917","markdown":"https://insights.sbomify.com/CVE-2021-47917/index.md","name":"CVE-2021-47917","record":{"aliases":["GHSA-pgc8-g7q5-fq5m"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Simple CMS","requires_auth":"low_privilege","summary":"Remote attackers can inject persistent scripts via user input parameters in Simple CMS, leading to session hijacking and application manipulation.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"simple_cms_php","vendor":"simplephpscripts"}],"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":"Simple CMS 2.1 contains a persistent cross-site scripting vulnerability in user input parameters that allows remote attackers to inject malicious script code.
