{"id":"CVE-2026-1541","state":"PUBLISHED","title":"Avada (Fusion) Builder <= 3.15.1 - Authenticated (Subscriber+) Sensitive Information Exposure via Insecure Direct Object Reference","description":"The Avada (Fusion) Builder plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.15.1. This is due to the plugin's `fusion_get_post_custom_field()` function failing to validate whether metadata keys are protected (underscore-prefixed). This makes it possible for authenticated attackers, with Subscriber-level access and above, to extract protected post metadata fields that should not be publicly accessible via the Dynamic Data feature's `post_custom_field` parameter.","publishedAt":"2026-04-15T01:25:17.892Z","updatedAt":"2026-04-15T15:56:52.964Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["themefusion Avada (Fusion) Builder"],"affected":[{"vendor":"themefusion","product":"Avada (Fusion) Builder","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.15.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/f1f69f93-80e3-434d-98a6-fc8757b4e6d1?source=cve","https://themeforest.net/item/avada-responsive-multipurpose-theme/2833226"],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/1xxx/CVE-2026-1541.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-1541","state":"PUBLISHED","datePublished":"2026-04-15T01:25:17.892Z","dateUpdated":"2026-04-15T15:56:52.964Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-01-28T14:57:30.708Z"},"containers":{"cna":{"title":"Avada (Fusion) Builder <= 3.15.1 - Authenticated (Subscriber+) Sensitive Information Exposure via Insecure Direct Object Reference","descriptions":[{"lang":"en","value":"The Avada (Fusion) Builder plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.15.1.
