The server processes these \npaths without validation, resulting in outbound connection attempts to \nattacker-controlled SMB servers. This enables authenticated attackers to\n trigger the server to authenticate to arbitrary SMB endpoints, \npotentially exposing NTLM authentication information (such as NTLM \nhashes). If outbound connections to port 445 (SMB) are permitted, \nattackers can use this to conduct SMB relay or credential theft attacks.\n Exploitation of the “pathname” parameter is possible without \nauthentication. This issue affects TeamDavid before Rollout 528.\n\nStarting with Rollout 528 (June 30, 2026), the affected functionality is disabled by default and the vulnerabilities are therefore no longer exposed through this functionality.","published":"2026-08-07T10:16:57.000Z","lastModified":"2026-10-24T16:10:00.000Z","status":"Deferred","sourceIdentifier":"vulnerability@ncsc.ch","cvss":{"version":"4.0","score":6.3,"severity":"MEDIUM","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:H/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-20","CWE-918"],"affected":[],"epss":{"score":0.00491,"percentile":0.41975,"date":"2026-10-27","history":[]},"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 (0.49%).
