AI description

Automated description summarized from trusted sources.

CVE-2026-90817 describes an unauthenticated Remote Code Execution (RCE) vulnerability affecting REDCap versions 13.3.0 and higher. This flaw resides within the survey passthrough routing and Data Import processing logic of the software. A malicious actor could exploit this vulnerability by manipulating HTTP requests to access an unintended controller route from a public survey context. This is achieved by supplying a specially crafted file-path or stream parameter during the import handling process. Successful exploitation allows for the remote execution of arbitrary code on the REDCap server, though knowledge of a valid public survey hash is required.

Description: 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.
