Published: 2021-08-16 · updated 2026-06-17
Weakness: CWE-79

Description

The Photo Gallery by 10Web – Mobile-Friendly Image Gallery WordPress plugin before 1.5.75 did not ensure that uploaded SVG files added to a gallery do not contain malicious content. As a result, users allowed to add images to gallery can upload an SVG file containing JavaScript code, which will be executed when accessing the image directly (ie in the /wp-content/uploads/photo-gallery/ folder), leading to a Cross-Site Scripting (XSS) issue
