Open Redirect in snipe/snipe-it (CVE-2026-55461)
Summary
Vulnerability in snipe/snipe-it (CVE-2026-55461). Risk of unauthorized operations or information disclosure. Exploitable via Referer. Mitigation: upgrade to 8.6.2 or later.
Original description
The description as published by the source.
Impact
The user edit flow stores url()->previous() into Laravel's intended URL session value and later redirects with redirect()->intended(...) when redirect_option=back is submitted. Because the previous URL is derived from the attacker-controlled Referer header, an authenticated user performing a normal user-edit action can be redirected to an external attacker-controlled site.
An attacker who can cause a logged-in user with permission to edit a user record to open the edit page with an attacker-controlled Referer value.
The application can be used as a trusted redirector after a legitimate user edit action. This can support phishing or trust-boundary attacks against Snipe-IT users and matches a historical open redirect class where session-stored navigation context influences redirect destinations.
