{"id":"CVE-2026-114470","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-114470","generatedAt":"2026-10-28T03:39:35.558Z","title":"Cross-site request forgery in the REST API of Progressive Robot hMailServer 6.0.0 through 6.3.6 allows a remote attacker to make an authenticated user's browser perform a state-changing request.","description":"Cross-site request forgery in the REST API of Progressive Robot hMailServer 6.0.0 through 6.3.6 allows a remote attacker to make an authenticated user's browser perform a state-changing request. The REST API accepts HTTP Basic authentication and answers a browser with a Basic sign-in box; a browser caches the credential once the box is answered and sends it with later requests to that origin, including a top-level form post from another site, and the server reads a request body whatever its declared content type. The cross-site protection covered only the cookie session (a header a cross-site form cannot set, and a SameSite=Strict cookie); HTTP Basic was not held to it. A page under an attacker's control, visited by a user whose browser holds a cached Basic credential for the REST API - typically an administrator who signed in through the box - could therefore cause a state-changing request such as creating a domain, an account or an API key, or changing a setting, with the victim's credential. The attacker cannot read the cross-origin response, so the forgery is blind.","published":"2026-10-21T16:17:34.000Z","lastModified":"2026-10-22T16:18:19.000Z","status":"Awaiting Analysis","sourceIdentifier":"cve@gitlab.com","cvss":{"version":"3.1","score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:H/A:N"},"cwe":["CWE-352"],"affected":[],"epss":{"score":0.00153,"percentile":0.04358,"date":"2026-10-27","history":[{"date":"2026-10-22","score":0.00153,"percentile":0.04063}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.15%).
