Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-2354 in the wild and no public exploit code.\n\nAffected product: wpmessiah Swiss Toolkit For WP. 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-2026-2354/ (Markdown: https://insights.sbomify.com/CVE-2026-2354/index.md)","id":"CVE-2026-2354","markdown":"https://insights.sbomify.com/CVE-2026-2354/index.md","name":"CVE-2026-2354","record":{"aliases":["GHSA-xq2v-8qf4-3rg6"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated attackers can upload arbitrary files, including PHP, leading to remote code execution if the Enhanced Multi-Format Image Support feature is enabled.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[],"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 Swiss Toolkit For WP plugin for WordPress is vulnerable to arbitrary file upload due to a flawed file type validation bypass in the `upload_extension_files()` function in all versions up to, and including, 1.4.6. The `upload_extension_files()` function hooks into WordPress's `wp_check_filetype_and_ext` filter and uses `strpos()` to check if a filename contains a configured extension string, rather than verifying the actual file extension. This makes it possible for authenticated attackers, with Author-level access and above, to upload arbitrary files (including PHP) on the affected site's server which may make remote code execution possible, granted the \"Enhanced Multi-Format Image Support\" feature is enabled with at least one extension (e.g., avif) in the allowed formats.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Swiss Toolkit For WP \u003c= 1.4.6 - Authenticated (Author+) Arbitrary File Upload via upload_extension_files()","id":"CVE-2026-2354","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"Cross-site scripting in My Calendar – Accessible Event Manager","id":"CVE-2026-2355"},"packages":[],"prev":{"headline":"Autoptimize \u003c= 3.1.14 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'ao_post_preload' Meta Value","id":"CVE-2026-2352"},"products":["Swiss Toolkit For WP"],"published":"2026-07-11","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-13","vendors":["wpmessiah"]},"summary":"Authenticated attackers can upload arbitrary files, including PHP, leading to remote code execution if the Enhanced Multi-Format Image Support feature is enabled.","url":"https://insights.sbomify.com/CVE-2026-2354/"}
