{"id":"CVE-2024-5726","state":"PUBLISHED","title":"Timeline Event History <= 3.1 - Authenticated (Contributor+) PHP Object Injection","description":"The Timeline Event History plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.1 via deserialization of untrusted input 'timelines-data' parameter. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software. 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":"2024-07-18T02:03:55.800Z","updatedAt":"2026-04-08T16:36:00.011Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["wpdiscover Timeline Event History"],"affected":[{"vendor":"wpdiscover","product":"Timeline Event History","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/107afaa6-6c0b-43fb-9713-ebc4f1189ea6?source=cve","https://plugins.trac.wordpress.org/browser/timeline-event-history/trunk/includes/admin/timeline-wp-build.php#L5","https://plugins.trac.wordpress.org/browser/timeline-event-history/trunk/includes/public/templates/style-another/index.php#L5","https://plugins.trac.wordpress.org/browser/timeline-event-history/trunk/includes/public/templates/style-one/index.php#L7","https://plugins.trac.wordpress.org/changeset/3141560/"],"weaknesses":["CWE-502"],"ingestedAt":"2026-10-29T20:08:12.933Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2024/5xxx/CVE-2024-5726.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2024-5726","state":"PUBLISHED","datePublished":"2024-07-18T02:03:55.800Z","dateUpdated":"2026-04-08T16:36:00.011Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2024-06-07T00:45:17.808Z"},"containers":{"cna":{"title":"Timeline Event History <= 3.1 - Authenticated (Contributor+) PHP Object Injection","descriptions":[{"lang":"en","value":"The Timeline Event History plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.1 via deserialization of untrusted input 'timelines-data' parameter.
