{"id":"CVE-2023-5583","state":"PUBLISHED","title":"WP Simple Galleries <= 1.34 - Authenticated (Contributor+) PHP Object Injection","description":"The WP Simple Galleries plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 1.34 via deserialization of untrusted input from the 'wpsimplegallery_gallery' post meta via 'wpsgallery' shortcode. This allows authenticated attackers, with contributor-level permissions 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":"2023-10-30T13:48:45.699Z","updatedAt":"2026-04-08T16:35:20.142Z","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":["maca134 WP Simple Galleries"],"affected":[{"vendor":"maca134","product":"WP Simple Galleries","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.34","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/0dc8f7cf-d8be-4229-b823-3bd9bc9f6eda?source=cve","https://plugins.trac.wordpress.org/browser/wp-simple-galleries/tags/1.34/wp-simple-gallery.php#L250"],"weaknesses":["CWE-502"],"ingestedAt":"2026-10-29T20:06:42.242Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/5xxx/CVE-2023-5583.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2023-5583","state":"PUBLISHED","datePublished":"2023-10-30T13:48:45.699Z","dateUpdated":"2026-04-08T16:35:20.142Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2023-10-13T22:35:07.689Z"},"containers":{"cna":{"title":"WP Simple Galleries <= 1.34 - Authenticated (Contributor+) PHP Object Injection","descriptions":[{"lang":"en","value":"The WP Simple Galleries plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 1.34 via deserialization of untrusted input from the 'wpsimplegallery_gallery' post meta via 'wpsgallery' shortcode.
