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-2026-18438/ (Markdown: https://insights.sbomify.com/CVE-2026-18438/index.md)","id":"CVE-2026-18438","markdown":"https://insights.sbomify.com/CVE-2026-18438/index.md","name":"CVE-2026-18438","record":{"aliases":["GHSA-wqqc-79qg-345q"],"analysis":{"component_type":"cms_plugin","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated contributors can achieve remote code execution by uploading malicious files due to filename validation mismatches in the Templately WordPress plugin.","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 Templately – Elementor \u0026 Gutenberg Template Library: 6500+ Free \u0026 Pro Ready Templates And Cloud! plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 3.7.1 via the fetch_remote_file function. This is due to a filename validation/destination mismatch in fetch_remote_file, where file type validation is performed against the attacker-controlled Content-Disposition filename rather than the URL-path-derived destination filename. This makes it possible for authenticated attackers, with contributor-level access and above, to execute code on the server. A GIF+PHP polyglot file passes wp_check_filetype_and_ext validation as image/gif via the Content-Disposition filename, while the actual destination path is written with a .php extension derived from the URL path, bypassing the unfiltered_upload capability gate entirely. The affected endpoints are reachable at this privilege level because Templately's entire REST API — including the cloud import endpoints used in this attack (/templately/v1/clouds/upload and /templately/v1/insert) — is authorized only by a current_user_can('delete_posts') check, with no administrator or manage_options capability requirement. The same permission gate also allows a contributor to overwrite the site's global Templately cloud connection via the /templately/v1/login endpoint with global_signin set to true. A complete remediation should both correct fetch_remote_file to validate the file type against the actual destination filename rather than the Content-Disposition header (and avoid deriving the write path from the request URL), and restrict state-changing Templately REST routes to an appropriate administrator-level capability.","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":"File upload in Templately – Elementor \u0026 Gutenberg Template Library: 6500+ Free \u0026 Pro Ready Templates And Cloud!","id":"CVE-2026-18438","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2026"},"n_packages":0,"n_references":18,"next":{"headline":"Missing authorization in Tutor LMS – eLearning and online course solution","id":"CVE-2026-18439"},"packages":[],"prev":{"headline":"MailPress \u003c= 1.5.0 - Missing Authorization to Unauthenticated Contact Updates","id":"CVE-2026-18437"},"products":["Templately – Elementor \u0026 Gutenberg Template Library: 6500+ Free \u0026 Pro Ready Templates And Cloud!"],"published":"2026-08-15","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":"2026-08-17","vendors":["wpdevteam"]},"summary":"Authenticated contributors can achieve remote code execution by uploading malicious files due to filename validation mismatches in the Templately WordPress plugin.","url":"https://insights.sbomify.com/CVE-2026-18438/"}
