{"id":"ALPINE-CVE-2026-104715","details":"A flaw was found in cifs-utils. This flaw allows an unprivileged local user to achieve privilege escalation. When a privileged service mounts a Common Internet File System (CIFS) share using a user-controlled credentials file, input values are not properly sanitized before being assembled into mount options. A local attacker can exploit this vulnerability to inject unauthorized mount options, allowing them to bypass permission checks and execute files with administrative (root) privileges.","modified":"2026-10-23T18:30:02.502701041Z","published":"2026-10-16T07:17:08.090Z","upstream":["CVE-2026-104715"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-104715"}],"affected":[{"package":{"name":"cifs-utils","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/cifs-utils?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.1-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-104715.json"}},{"package":{"name":"cifs-utils","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/cifs-utils?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.3-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-104715.json"}},{"package":{"name":"cifs-utils","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/cifs-utils?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.4-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-104715.json"}},{"package":{"name":"cifs-utils","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/cifs-utils?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.5-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-104715.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
