{"schemaVersion":3,"id":"CVE-2026-11426","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"The UnderConstructionPage PRO plugin for WordPress is vulnerable to Arbitrary File Read in all versions up to, and including, 5.76. This is due to the plugin accepting arbitrary local file paths in the template_thumbnail parameter and copying their contents into a publicly accessible uploads file. This makes it possible for authenticated attackers, with Subscriber-level access and above, to read arbitrary files on the server, which can contain sensitive information.","dates":{"published":"2026-07-11T01:29:19.028Z","modified":"2026-07-13T17:43:52.129Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.5,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"wordfence","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.0046,"percentile":0.38556,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-20T00:00:00.000Z","baselineScore":0.0046},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.0046,"percentile":0.38556}],"last30":[{"date":"2026-09-20T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.0046,"percentile":null},{"date":"2026-10-08T00:00:00.
