Idno Vulnerable to Unauthenticated SSRF via URL Unfurl Endpoint

A logic error in the API authentication flow causes the CSRF protection on the URL unfurl service endpoint to be trivially bypassed by any unauthenticated remote attacker. Combined with the absence of a login requirement on the endpoint itself, this allows an attacker to force the server to make arbitrary outbound HTTP requests to any host, including internal network addresses and cloud instance metadata services, and retrieve the response content.

Idno Vulnerable to Remote Code Execution via Chained Import File Write and Template Path Traversal

Two separate vulnerabilities in Idno can be chained to achieve RCE from a web application admin account. A web application admin can cause the server to fetch an attacker-controlled URL during WordPress import processing, writing a PHP file to the server's temp directory. The admin or a separate, lower-privileged authenticated user can then trigger inclusion of that file via an unsanitized template name parameter, executing arbitrary operating system commands as …

Known affected by Account Takeover via Password Reset Token Leakage

A Critical Broken Authentication vulnerability exists in Known 1.6.2. The application leaks the password reset token within a hidden HTML input field on the password reset page. This allows any unauthenticated attacker to retrieve the reset token for any user by simply querying the user's email, leading to full Account Takeover (ATO) without requiring access to the victim's email inbox.
