CVE-2026-67178

/// Technical description

MISP installation scripts generated an Apache HTTP virtual-host configuration containing an incorrectly formatted HTTP-to-HTTPS redirect:

Redirect permanent / https://misp.example

Apache’s Redirect directive appends any portion of the requested path that follows the matched prefix to the configured destination URL. Because the destination did not end with /, attacker-controlled path content was appended directly to the hostname rather than to its URL path.

For example, a request resembling:

http://misp.example/@attacker.example/

could result in a redirect resembling:

https://[email protected]/

Under standard URL parsing, misp.example is interpreted as user information and attacker.example as the destination host. An unauthenticated remote attacker could therefore construct a URL hosted under the legitimate MISP domain that redirects users to an attacker-controlled website.

The vulnerability could be used for phishing, credential collection, or potentially disclosing
