{"id":"CVE-2024-4838","state":"PUBLISHED","title":"ConvertPlus <= 3.5.26 - Authenticated (Contributor+) PHP Object Injection","description":"The ConvertPlus plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.5.26 via deserialization of untrusted input from the 'settings_encoded' attribute of the 'smile_modal' shortcode. This makes it possible for authenticated attackers, with contributor-level access and above, to inject a PHP Object. No POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.","publishedAt":"2024-05-16T11:05:27.037Z","updatedAt":"2026-04-08T16:37:16.264Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["Brainstorm Force ConvertPlus"],"affected":[{"vendor":"Brainstorm Force","product":"ConvertPlus","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.5.26","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/16f5a104-dce0-4249-91b9-67f99cce16d3?source=cve","https://www.convertplug.com/plus/"],"weaknesses":["CWE-502"],"ingestedAt":"2026-10-29T20:07:56.516Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2024/4xxx/CVE-2024-4838.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2024-4838","state":"PUBLISHED","datePublished":"2024-05-16T11:05:27.037Z","dateUpdated":"2026-04-08T16:37:16.264Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2024-05-13T16:21:48.419Z"},"containers":{"cna":{"title":"ConvertPlus <= 3.5.26 - Authenticated (Contributor+) PHP Object Injection","descriptions":[{"lang":"en","value":"The ConvertPlus plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.5.26 via deserialization of untrusted input from the 'settings_encoded' attribute of the 'smile_modal' shortcode.
