SA-CONTRIB-2012-174 - Context - Information Disclosure

Context has functionality that renders block content for use with its inline editor. When these requests are made the context module does not sufficiently ensure that users have access to the block. A malicious user could send a specially crafted request and get access to block content they should not be able to see.

This vulnerability is mitigated by the fact that an attacker must know the identifiers for the block containing sensitive information and that the block’s code must render that sensitive information when requested by a user without privileges to see this information.
