  1. Affected≤ 2.5.7
  2. Patched in2.5.8

Update to 2.5.8 or newer.

You are affected if you run ≤ 2.5.7. Version 2.5.8 and later are not affected by this issue.

  • No admin access? Run a passive check of your site. It reads public files only.

What to do

  2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
  3. Watch SVG Support to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Nathanial Lattimer (d0nut).

The SVG Support plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the SVG upload feature in all versions up to, and including, 2.5.7 due to insufficient input sanitization and output escaping, even when the 'Sanitize SVG while uploading' feature is enabled. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Note that successful exploitation of this vulnerability requires the administrator to allow author-level users to upload SVG files. As of 2.5.6, SVG sanitization can still be bypassed by supplying a content-type other than image/svg+xml.
