Summary

The WP Chill Gallery PhotoBlocks plugin (photoblocks-grid-gallery) for WordPress is affected in versions through 1.3.7. Input is not neutralized when web pages are generated (CWE-79), so stored script is kept and runs in the browser of anyone who views the affected content. An attacker with low privileges can plant this script, and it runs when a victim interacts with the page.
