Idno is a social publishing platform. Prior to version 1.6.4, 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. This issue has been patched in version 1.6.4.

Affected: Packagist: idno/known

## Summary 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.

**Component**: `Idno/Pages/Service/Web/UrlUnfurl.php`, `Idno/Core/Session.php`, `Idno/Core/Actions.php` **Vulnerability Class**: [Server-Side Request Forgery (SSRF)](https://cwe.mitre.org/data/definitions/918.html) **Authentication Required**: None **CVSSv4 Base Score:** 9.2 (High) - [AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N](https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N) **Affected Endpoint**: GET `/service/web/unfurl?url=<attacker-controlled-url>` Handled by `Idno\Pages\Service\Web\UrlUnfurl::getContent()`. **Affected Versions**: <= 1.6.3 ``` cat version.idno version = '1.6.3' build = 2026021301 ```

## Code Flow ### Step 1 — Endpoint access control `UrlUnfurl::getContent()` (UrlUnfurl.php:36) enforces two access controls: `$this->xhrGatekeeper();` `$this->tokenGatekeeper();`

Notably, the original authentication check (`$this->gatekeeper()`) was explicitly removed with the following comment left in the source:

```php //$this->gat…
