{"id":"USN-8857-1","summary":"kf6-kcoreaddons vulnerability","details":"It was discovered that KCoreAddons incorrectly handled shell argument\nquoting in KShell::quoteArgs. The parsing did not adequately handle shell\nmetacharacters, which could lead to a shell escape. An attacker could\npossibly use this issue to execute arbitrary commands in applications that\nrelied on this method to handle user input.","modified":"2026-10-02T00:42:36.520185156Z","published":"2026-10-01T10:48:57Z","related":["UBUNTU-CVE-2026-41526"],"upstream":["CVE-2026-41526","UBUNTU-CVE-2026-41526"],"references":[{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-8857-1"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-41526"}],"affected":[{"package":{"name":"kf6-kcoreaddons","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/kf6-kcoreaddons?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.24.0-0ubuntu1.1"}]}],"versions":["6.17.0-0ubuntu1","6.19.0-0ubuntu1","6.20.0-0ubuntu1","6.21.0-0ubuntu1","6.22.0-0ubuntu1","6.23.0-0ubuntu1","6.24.0-0ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_version":"6.24.0-0ubuntu1.1","binary_name":"libkf6coreaddons-data"},{"binary_name":"libkf6coreaddons6","binary_version":"6.24.0-0ubuntu1.1"},{"binary_name":"qml6-module-org-kde-coreaddons","binary_version":"6.24.0-0ubuntu1.1"}],"availability":"No subscription required"},"database_specific":{"cves_map":{"ecosystem":"Ubuntu:26.04:LTS","cves":[{"id":"CVE-2026-41526","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:L"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}]},"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/usn/USN-8857-1.json"}}],"schema_version":"1.9.0"}
