Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-4354 in the wild and no public exploit code.\n\nAffected product: magazine3 PWA for WP – Progressive Web Apps Made Simple. 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-2021-4354/ (Markdown: https://insights.sbomify.com/CVE-2021-4354/index.md)","id":"CVE-2021-4354","markdown":"https://insights.sbomify.com/CVE-2021-4354/index.md","name":"CVE-2021-4354","record":{"aliases":["GHSA-w75r-hmw9-3gxm"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated attackers can upload arbitrary files via missing validation, potentially leading to remote code execution on WordPress sites.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[{"product":"pwa_for_wp_\\\u0026_amp","vendor":"magazine3"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"The PWA for WP \u0026 AMP for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the pwaforwp_splashscreen_uploader function in versions up to, and including, 1.7.32.
