Name of the Vulnerable Software and Affected Versions The Better Search plugin for WordPress versions up to, and including, 2.5.2

Description The issue is related to Cross-Site Request Forgery due to missing or incorrect nonce validation on the bsearch process settings import() and bsearch process settings export() functions.
