What is CVE-2025-62709?

CVE-2025-62709 is a medium-severity vulnerability in MacWarrior clipbucket-v5, published on 20 Nov 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

Official description

ClipBucket v5 is an open source video sharing platform. In ClipBucket version 5.5.2, a change to network.class.php causes the application to dynamically build the server URL from the incoming HTTP Host header when the configuration base_url is not set. Because Host is a client-controlled header, an attacker can supply an arbitrary Host value. This allows an attacker to cause password-reset links (sent by forget.php) to be generated with the attacker’s domain. If a victim follows that link and enters their activation code on the attacker-controlled domain, the attacker can capture the code and use it to reset the victim’s password and take over the account. This issue has been patched in version 5.5.2#162.
