Stored XSS in Image Photo Gallery Final Tiles Grid WordPress Plugin

Publication date: 2026-10-08

Last updated on: 2026-10-08

Assigner: WPScan

Description
The Image Photo Gallery Final Tiles Grid WordPress plugin before 3.6.14 does not sanitise several gallery configuration values that can be overridden through its gallery shortcode before printing them into an inline script block, allowing users with contributor-level access and above to inject arbitrary JavaScript that executes in the session of anyone viewing the post, including an administrator previewing a pending submission. No gallery ownership is required: any gallery that already exists on the site can be referenced.
