The Album and Image Gallery with Lightbox – Flagallery Photo Portfolio plugin for WordPress is vulnerable to a security issue in versions up to, and including, 2.00. This issue allows hackers who have administrator-level permissions to access the website to modify existing files and add malicious code. This could cause the website to be compromised and the hacker could gain control of the website. To fix this issue, users should update the plugin to the latest version available.
