{"schemaVersion":3,"id":"CVE-2025-12359","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"The Responsive Lightbox & Gallery plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 2.5.3 via the 'get_image_size_by_url' function. This is due to insufficient validation of user-supplied URLs when determining image dimensions for gallery items. This makes it possible for authenticated attackers, with Author-level access and above, to make web requests to arbitrary locations originating from the web application which can be used to query and modify information from internal services.","dates":{"published":"2025-11-19T05:45:14.684Z","modified":"2026-04-08T17:03:19.715Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5.4,"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:L/I:L/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":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":"wordfence","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}]},"epss":{"probability":0.00255,"percentile":0.16188,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0.017,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.00238},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00255,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00255,"percentile":0.16188}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00238,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score
