The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
How to Fix CVE-2026-13352
To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:treeHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2026-13352, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:treeAnalyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.
Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

"details" : "The Paid Membership Plugin, Ecommerce, User Registration Form, Login Form, User Profile & Restrict Content – ProfilePress plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 4.16.18 via the allowed_mime_types function. This is due to the unconditional registration of an upload_mimes filter that adds executable file extensions (.exe, .apk, .msi) to the global WordPress MIME allowlist, without scoping the expansion to digital-product upload contexts. This makes it possible for authenticated attackers, with author-level access and above, to upload files that may be executable, which makes remote code execution possible. This filter is registered globally on every request regardless of whether the digital products feature is configured or in use, meaning the expanded MIME allowlist affects all WordPress upload contexts site-wide.",
