CVE-2024-56261Network attack vector

Contributor-level stored cross-site scripting

Published Jan 2, 2025 · Updated Apr 28, 2026

Stored XSS in GS Plugins Project Showcase 1.1.1 and earlier allows remote authenticated users to execute scripts in visitors' browsers. Patchstack has not disclosed the affected field, shortcode attribute, or output routine, so the precise missing sanitization or escaping operation is not public. Contributor-level access is required to store the payload, and exploitation requires another user to view the affected content; the documented impact is browser-side script execution.
