CVE-2026-87067

high · CVSS 8.5 · Forminator Forms

The Forminator Forms WordPress plugin before 1.57.2.1 does not restrict which classes may be instantiated when it deserialises a value taken from an XML-RPC request, allowing users who hold its forms-management permission to write a file of their choosing and execute arbitrary code. That permission belongs to an administrator by default, and to any role the site has granted it through the Forminator Forms WordPress plugin before 1.57.2.1's own settings, so the issue is reachable well below administrator on sites that use that feature.

CVE-2026-90817

critical · CVSS 9.8 · Vanderbilt University REDCap

An unauthenticated Remote Code Execution vulnerability was found in the survey passthrough routing and Data Import processing logic, in which a malicious user could potentially exploit it by manipulating HTTP requests to access an unintended controller route from a public survey context and by supplying a crafted file-path/stream parameter during import handling. If successfully exploited, this could allow the attacker to remotely execute arbitrary code on the REDCap server. The attacker does not have to be authenticated in order to exploit this, but exploitation requires knowledge of a valid public survey hash. This vulnerability exists in REDCap 13.3.0 and higher.
