Summary

Drupal Webform versions from 0.0.0 before 6.2.12 and from 6.3.0 before 6.3.1 are affected. Improper neutralization of input during web page generation lets users store script that the site then renders in web pages (CWE-79). An attacker with low privileges can exploit this when a user interacts with the affected page, running script in that user's browser.
