{"schemaVersion":3,"id":"CVE-2026-27748","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Avira Internet Security contains an improper link resolution vulnerability in the Software Updater component. During the update process, a privileged service running as SYSTEM deletes a file under C:\\\\ProgramData without validating whether the path resolves through a symbolic link or reparse point. A local attacker can create a malicious link to redirect the delete operation to an arbitrary file, resulting in deletion of attacker-chosen files with SYSTEM privileges. This may lead to local privilege escalation, denial of service, or system integrity compromise depending on the targeted file and operating system configuration.","dates":{"published":"2026-03-05T14:15:48.976Z","modified":"2026-04-01T14:37:46.139Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.8,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":7.8,"severity":"high","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7.1,"severity":"high","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00194,"percentile":0.08512,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":0.015000000000000017,"baselineDate":"2026-09-20T00:00:00.000Z","baselineScore":0.00179},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00179,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00179,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00179,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00179,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00179,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00179,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00179,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00179,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00179,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00179,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00186,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00186,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00186,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00186,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00186,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00186,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00186,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00186,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00194,"percentile":0.08512}],"last30":[{"date":"2026-09-20T00:00:00.000Z","score":0.00179,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00179,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00179,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00179,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00186,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00186,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00186,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00186,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00186,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00186,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00186,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00186,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00194,"percentile":null},{"date":"2026-10-10
