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.
