Summary

Stored cross-site scripting in the Drupal Block Attributes module lets attackers inject script into web pages that other users then load. The module affects versions from 0.0.0 before 2.1.0. An attacker with high privileges needs a user to interact with the page to exploit it, and a successful attack can change the scope of the impact, with limited effects on confidentiality, integrity and availability. The weakness is CWE-79, improper neutralization of input during web page generation.
