{"id":"CVE-2026-5753","state":"PUBLISHED","title":"All-in-One WP Migration Unlimited Extension <= 2.83 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Backup Schedule Creation and Backup File Download","description":"The All-in-One WP Migration Unlimited Extension plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 2.83. This is due to the 'Ai1wmve_Schedules_Controller::save' handler for 'admin_post_ai1wm_schedule_event_save' not verifying user capabilities before saving schedule data. This makes it possible for authenticated attackers, with subscriber-level access and above, to create scheduled export jobs and send backup notifications to attacker-controlled email addresses. Because such notifications include the random backup filename, full site backups can subsequently be downloaded from the target site, resulting in sensitive information exposure.","publishedAt":"2026-05-06T03:27:21.807Z","updatedAt":"2026-05-06T12:57:42.449Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["servmask All-in-One WP Migration Unlimited Extension"],"affected":[{"vendor":"servmask","product":"All-in-One WP Migration Unlimited Extension","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.83","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/a8a31080-c124-49be-b9d1-7bc5abe7cbda?source=cve","https://help.servmask.com/knowledgebase/unlimited-extension-changelog/"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:12:32.778Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/5xxx/CVE-2026-5753.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-5753","state":"PUBLISHED","datePublished":"2026-05-06T03:27:21.807Z","dateUpdated":"2026-05-06T12:57:42.449Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-04-07T16:14:53.795Z"},"containers":{"cna":{"title":"All-in-One WP Migration Unlimited Extension <= 2.83 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Backup Schedule Creation and Backup File Download","descriptions":[{"lang":"en","value":"The All-in-One WP Migration Unlimited Extension plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 2.83.
