{"id":"CVE-2026-115517","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-115517","generatedAt":"2026-10-28T01:53:34.840Z","title":"Unrestricted network access between execution contexts in KNIME Business Hub before version 1.19.0 allows an authenticated remote user to access open network ports on executors in different execution contexts.","description":"Unrestricted network access between execution contexts in KNIME Business Hub before version 1.19.0 allows an authenticated remote user to access open network ports on executors in different execution contexts. This only poses a security issue if the IP address of the attacked executor is know and there are open network ports that provided access without further authentication. By default no network ports are open. However, depending on the running workflows, ports may be opened and provide an attack surface. As a workaround, network policies can be created manually.","published":"2026-10-22T19:17:49.000Z","lastModified":"2026-10-23T19:43:46.000Z","status":"Awaiting Analysis","sourceIdentifier":"security@knime.com","cvss":{"version":"4.0","score":6.4,"severity":"MEDIUM","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:L/SI:H/SA:H/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-653"],"affected":[],"epss":{"score":0.00431,"percentile":0.37042,"date":"2026-10-26","history":[{"date":"2026-10-23","score":0.00431,"percentile":0.36253}]},"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 (0.43%).
