What is CVE-2026-90817?

An unauthenticated Remote Code Execution vulnerability affects REDCap, enabling attackers to exploit the survey passthrough routing and Data Import processing. By manipulating HTTP requests, a malicious user can target an unintended controller route from a public survey context and provide a crafted file-path or stream parameter during import handling. Successful exploitation allows the attacker to remotely execute arbitrary code on the REDCap server. Although authentication is not required, knowledge of a valid public survey hash is essential for exploitation. This vulnerability is present in REDCap versions 13.3.0 and above.

Affected Version(s)

REDCap 13.3.0

REDCap 16.0.49

REDCap 17.3.10

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
