CVE-2026-115243 Details
Description
The WPvivid — Backup, Migration & Staging WordPress plugin before 0.9.137 does not validate the extension of the file it actually stores when handling an import upload: it checks the extension of a separate request field while saving the uploaded file itself with WordPress's upload type-checking disabled, so an authenticated administrator can store a file with an arbitrary extension, including a PHP file, in the WPvivid — Backup, Migration & Staging WordPress plugin before 0.9.137's import directory. This is an incomplete fix of CVE-2025-5961, whose extension check was applied to the wrong value.
A vulnerability exists in the WPvivid Backup, Migration & Staging WordPress plugin in versions prior to 0.9.137, allowing authenticated administrators to upload files with arbitrary extensions, including PHP files. The issue arises because the plugin fails to properly validate file extensions during import uploads. Instead, it checks a separate request field while disabling WordPress's standard upload type validation, enabling the upload of potentially malicious files into the import directory. This vulnerability is an incomplete fix of CVE-2025-5961, where the extension check was applied incorrectly.
Users are advised to update the WPvivid Backup, Migration & Staging WordPress plugin to version 0.9.137 or later.
