| 2026-09-17 | CSRF | Bypassing Referer-Based CSRF with strict-origin-when-cross-origin | Technique bypassing Referer-based CSRF attacks by exploiting the `strict-origin-when-cross-origin` referrer policy. This policy, default in major browsers, sets the Referer header to the origin of the document initiating a request, even if the top-level page is different. This allows an attacker to host a `text/css` or JavaScript module file on the target domain, which then makes a request back to a vulnerable endpoint. When this file is linked from the attacker's own page, the browser sends the target's origin as the Referer, satisfying the check. The attack is further enhanced if the uploaded file can be linked from a same-origin subdomain, allowing it to carry session cookies. |
