An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-47746 exists.\n\nAffected product: NodeBB Plugin Emoji. 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-2021-47746/ (Markdown: https://insights.sbomify.com/CVE-2021-47746/index.md)","id":"CVE-2021-47746","markdown":"https://insights.sbomify.com/CVE-2021-47746/index.md","name":"CVE-2021-47746","record":{"aliases":["GHSA-g674-4q3h-w499"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"NodeBB Emoji plugin","requires_auth":"high_privilege","summary":"Administrative users can exploit directory traversal in the emoji upload API to write arbitrary files to system locations, potentially leading to code execution.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-73","name":"External Control of File Name or Path"}],"description":"NodeBB Plugin Emoji 3.2.1 contains an arbitrary file write vulnerability that allows administrative users to write files to arbitrary system locations through the emoji upload API.
