Description

The Share This Image plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'alignment' parameter in all versions up to, and including, 2.01 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

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

  • mihail-barinov Share This Image — Up to and including 2.01
  • share_this_image_project share_this_image — Before 2.02
