Cross-site scripting (XSS) vulnerability in the LiveSearch module in Plone before 3.0.4 allows remote attackers to inject arbitrary web script or HTML via the Description field for search results, as demonstrated using the onerror Javascript even in an IMG tag.

Plone 2.5 through 2.5.4 and 3.0 through 3.0.2 allows remote attackers to execute arbitrary Python code via network data containing pickled objects for the (1) statusmessages or (2) linkintegrity module, which the module unpickles and executes.

Plone 2.0.5, 2.1.2, and 2.5-beta1 does not restrict access to the (1) changeMemberPortrait, (2) deletePersonalPortrait, and (3) testCurrentPassword methods, which allows remote attackers to modify portraits.
