CVE-2026-57770

Name of the Vulnerable Software and Affected Versions Grand Photography versions prior to 5.7.9

Description Grand Photography is subject to PHP Object Injection due to the deserialization of untrusted data. This allows unauthenticated attackers to inject a PHP Object. While no POP chain (a sequence of gadgets used to achieve code execution) is present in the software itself, the presence of a POP chain via another installed plugin or theme could enable the deletion of arbitrary files, retrieval of sensitive data, or remote code execution.

Recommendations Update to a version newer than 5.7.8.
