CVE-2025-62675 is an HTTP response splitting vulnerability in the Web Filter warning page of Fortinet FortiOS and FortiProxy. Affected versions include FortiOS 7.6.0 through 7.6.4, all 7.4 versions, all 7.2 versions, and FortiProxy 7.6.0 through 7.6.4, all 7.4 versions, and all 7.2 versions. The flaw is caused by improper neutralization of CRLF sequences in HTTP headers, allowing attacker-controlled input associated with a web filter override workflow to be interpreted as additional HTTP header content. Exploitation requires the attacker to possess a valid web filter override token and to induce a user to follow a crafted link. Successful exploitation can result in arbitrary HTTP header injection in the server response.
