{"schemaVersion":3,"id":"CVE-2026-6848","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A flaw was found in Red Hat Quay. When Red Hat Quay requests password re-verification for sensitive operations, such as token generation or robot account creation, the re-authentication prompt can be bypassed. This allows a user with a timed-out session, or an attacker with access to an idle authenticated browser session, to perform privileged actions without providing valid credentials. The vulnerability enables unauthorized execution of sensitive operations despite the user interface displaying an error for invalid credentials.","dates":{"published":"2026-04-22T09:06:19.958Z","modified":"2026-04-22T12:55:24.902Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":8.1,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"NVD","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":5.4,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":8.1,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00386,"percentile":0.31282,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":0.12300000000000003,"baselineDate":"2026-09-20T00:00:00.000Z","baselineScore":0.00263},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00263,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00263,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00263,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00263,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00263,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00263,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00263,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00263,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00263,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00263,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00386,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00386,"percentile":0.31282}],"last30":[{"date":"2026-09-20T00:00:00.000Z","score":0.00263,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00263,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00263,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00263,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00376,"percentile":null},{"date":"2026-10-10T00:0
