{"id":"CVE-2026-115196","published":"2026-10-26T14:16:31.157","lastModified":"2026-10-26T16:17:17.003","description":"An Open Redirect vulnerability exists in the public form submission endpoint (/form/submit) of Mautic. After a form is submitted, the application redirects the visitor to a return address supplied with the submission without verifying that it points to the Mautic instance or another trusted host. An unauthenticated attacker can exploit this to send visitors from a legitimate Mautic domain to an arbitrary external website, for example to phishing pages that imitate the original landing page or to sites that deliver malware. Any Mautic instance with a published form is affected. Exploitation requires the victim to submit a form prepared by the attacker.","cvssScore":5.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","cwes":["CWE-601"],"vendors":[],"products":[],"references":[{"url":"https://github.com/mautic/mautic/security/advisories/GHSA-5mm3-3g7p-9868","tags":[]}],"exploitRefs":[{"url":"https://github.com/mautic/mautic/security/advisories/GHSA-5mm3-3g7p-9868","tags":[]}],"hasPoc":true,"ai":null}
