{"id":"CVE-2026-104730","published":"2026-10-16T07:17:08.267","lastModified":"2026-10-16T15:17:03.460","description":"The Sunshine Photo Cart – Client Photo Gallery & Photo Proofing for Photographers plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.7.4 via deserialization of untrusted input . This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present. If a POP chain is present via an additional plugin or theme installed on the target system, the attacker can store the malicious payload unauthenticated via the public favorites page and trigger deserialization by viewing any image in a non-viewable or private gallery.","cvssScore":9.8,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-502"],"vendors":[],"products":[],"references":[{"url":"https://plugins.trac.wordpress.org/browser/sunshine-photo-cart/tags/3.7.3/includes/class-frontend.php#L195","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/sunshine-photo-cart/tags/3.7.3/includes/class-image.php#L177","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/sunshine-photo-cart/tags/3.7.3/includes/class-session.php#L164","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/sunshine-photo-cart/tags/3.7.3/includes/class-session.php#L186","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3744492%40sunshine-photo-cart&new=3744492%40sunshine-photo-cart","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/b6f6b29e-1678-486c-a955-23d9247af0b5?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":{"summary":"The Sunshine Photo Cart plugin is vulnerable to PHP Object Injection during deserialization of untrusted input, allowing attackers to inject malicious PHP objects that can lead to remote code execution when combined with other vulnerable plugins or themes.","exploitability":"Exploitation requires an additional plugin or theme with a POP chain present, making it moderately difficult but possible for attackers to achieve RCE through the public favorites page and image viewing functionality.","blast_radius":"In real-world scenarios, this vulnerability could affect a significant number of WordPress sites using the plugin, especially those with other vulnerable components that could enable full compromise of the web application.","remediation":"Upgrade to version 3.7.5 or later to address the PHP Object Injection vulnerability.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["php","deserialization","wordpress","rce"],"model":"garnet-coder","analyzedAt":"2026-10-16T08:47:25.796Z"}}
