{"id":"CVE-2026-104730","kind":"vulnerability","aliases":["CVE-2026-104730"],"related":[],"title":"The Sunshine Photo Cart – Client Photo Gallery & Photo Proofing for Photographers plugin for WordPress is vulnerable…","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.","summary":"The Sunshine Photo Cart WordPress plugin up to and including 3.7.4 deserializes untrusted input, letting unauthenticated visitors inject a PHP object. On its own it has no code-execution path; the impact depends on a POP chain existing in another installed plugin or theme, which could allow deleting files, reading sensitive data, or running code.","severity":"critical","cvss":9.8,"epss":null,"exploited":false,"exploited_at":null,"products":[{"name":"sunshine-photo-cart","fixed":["3.7.5"],"affected":"<= 3.7.4","ecosystem":"wordpress"}],"ecosystems":[],"tags":["package","self-hosted","sunshine-photo-cart","wordpress"],"not_affected_if":["managed-hosting","plugin-not-installed","plugin-updated-past-3.7.4"],"how_to_check":"wp plugin get sunshine-photo-cart --field=version, or wp-admin > Plugins, or the Version header in wp-content/plugins/sunshine-photo-cart/sunshine-photo-cart.php. 3.7.4 or lower is affected.","fix":"Update Sunshine Photo Cart to 3.7.5 or later (3.8 is current, released 2026-10-21).
