{"id":"CVE-2024-11501","state":"PUBLISHED","title":"Gallery <= 1.3 - Authenticated (Contributor+) PHP Object Injection","description":"The Gallery plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.3 via deserialization of untrusted input from wd_gallery_$id parameter. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.","publishedAt":"2024-12-07T11:09:53.288Z","updatedAt":"2026-04-08T17:01:44.701Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["webdzier Gallery"],"affected":[{"vendor":"webdzier","product":"Gallery","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.3","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/778f7d9b-6376-4026-a291-1fedeabe8c99?source=cve","https://plugins.trac.wordpress.org/browser/multi-gallery/tags/1.3/partials/Shortcode.php#L21"],"weaknesses":["CWE-502"],"ingestedAt":"2026-10-29T20:06:50.777Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2024/11xxx/CVE-2024-11501.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2024-11501","state":"PUBLISHED","datePublished":"2024-12-07T11:09:53.288Z","dateUpdated":"2026-04-08T17:01:44.701Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2024-11-20T14:15:58.473Z"},"containers":{"cna":{"title":"Gallery <= 1.3 - Authenticated (Contributor+) PHP Object Injection","descriptions":[{"lang":"en","value":"The Gallery plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.3 via deserialization of untrusted input from wd_gallery_$id parameter.
