  "title": "cacti: Cacti is an open source performance and fault management framework",
  "description": "Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior are vulnerable to Open Redirect through a substring check rather than a host check at str_contains($referer, CACTI_PATH_URL). When the user\u0027s login_opts == \u00271\u0027 (redirect to referer after login), the function used $_SERVER[\u0027HTTP_REFERER\u0027] directly.  An attacker could craft a referer such as https://evil.com/cacti/. Where CACTI_PATH_URL is /cacti/, the substring matches and the user is redirected to evil.com after login. The pre-existing validate_redirect_url() helper at lib/html_utility.php performed proper validation but was not invoked from auth_login_redirect(). This issue has been fixed in version 1.2.31.",
