Description

The SVG Support WordPress plugin before 2.5.17 does not apply its SVG sanitisation to uploaded files using the .svgz extension, even though it registers and serves them as SVG, allowing a user permitted to upload SVGs (such as an Author once granted upload access) to store a script-bearing file that executes in the browser of anyone who later views it, including an administrator.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • Unknown SVG Support — Before 2.5.17
