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-2021-47913 exists.\n\nAffected product: PHPSUGAR PHP Melody. 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-2021-47913/ (Markdown: https://insights.sbomify.com/CVE-2021-47913/index.md)","id":"CVE-2021-47913","markdown":"https://insights.sbomify.com/CVE-2021-47913/index.md","name":"CVE-2021-47913","record":{"aliases":["GHSA-qg67-f99g-xghr"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"PHP Melody video platform","requires_auth":"low_privilege","summary":"Privileged users can inject persistent scripts via the video editor, enabling session hijacking and application manipulation in PHP Melody.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"php_melody","vendor":"phpsugar"}],"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":"PHP Melody 3.0 contains a persistent cross-site scripting vulnerability in the video editor that allows privileged users to inject malicious scripts.
