## From the sources

ProjectSend contains an improper authentication vulnerability that allows a remote, unauthenticated attacker to enable unauthorized modification of the application's configuration via crafted HTTP requests to options.php. Successful exploitation allows attackers to create accounts, upload webshells, and embed malicious JavaScript.

CISA required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
