description

Sunshine Photo Cart for WordPress through version 3.7.4 deserializes attacker-controlled data, allowing unauthenticated PHP object injection. Impact requires another installed plugin or theme to provide a usable POP chain, which could enable file deletion, data disclosure, or code execution.

mitigation

Disable Sunshine Photo Cart until a vendor release that corrects the issue can be installed. Audit and remove or update other plugins and themes that could provide PHP object deserialization chains, and restrict public access to affected galleries where possible.
