An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-13516 in the wild and no public exploit code.\n\nAffected product: brainstormforce SureMail – SMTP and Email Logs Plugin with Amazon SES, Postmark, and Other Providers. 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-2025-13516/ (Markdown: https://insights.sbomify.com/CVE-2025-13516/index.md)","id":"CVE-2025-13516","markdown":"https://insights.sbomify.com/CVE-2025-13516/index.md","name":"CVE-2025-13516","record":{"aliases":["GHSA-cmg2-755q-2pj5"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can upload malicious PHP files via email attachments to achieve remote code execution on sites using non-Apache or misconfigured web servers.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/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 SureMail – SMTP and Email Logs Plugin for WordPress is vulnerable to Unrestricted Upload of File with Dangerous Type in versions up to and including 1.9.0. This is due to the plugin's save_file() function in inc/emails/handler/uploads.php which duplicates all email attachments to a web-accessible directory (wp-content/uploads/suremails/attachments/) without validating file extensions or content types. Files are saved with predictable names derived from MD5 hashes of their content. While the plugin attempts to protect this directory with an Apache .htaccess file to disable PHP execution, this protection is ineffective on nginx, IIS, and Lighttpd servers, or on misconfigured Apache installations. This makes it possible for unauthenticated attackers to achieve Remote Code Execution by uploading malicious PHP files through any public form that emails attachments, calculating the predictable filename, and directly accessing the file to execute arbitrary code granted they are exploiting a site running on an affected web server configuration.","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 SureMail – SMTP and Email Logs Plugin with Amazon SES, Postmark, and Other Providers","id":"CVE-2025-13516","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2025"},"n_packages":0,"n_references":6,"next":{"headline":"SVG Map Plugin \u003c= 1.0.0 - Cross-Site Request Forgery to Settings Update and Stored Cross-Site Scripting","id":"CVE-2025-13519"},"packages":[],"prev":{"headline":"Nouri.sh Newsletter \u003c= 1.0.1.3 - Reflected Cross-Site Scripting via $_SERVER['PHP_SELF']","id":"CVE-2025-13515"},"products":["SureMail – SMTP and Email Logs Plugin with Amazon SES, Postmark, and Other Providers"],"published":"2025-12-02","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":"2026-04-08","vendors":["brainstormforce"]},"summary":"Unauthenticated attackers can upload malicious PHP files via email attachments to achieve remote code execution on sites using non-Apache or misconfigured web servers.","url":"https://insights.sbomify.com/CVE-2025-13516/"}
