Plague News contains a flaw that may allow an attacker to carry out an SQL injection attack. The issue is due to the index.php script not properly sanitizing user-supplied input to the 'cid' variable. This may allow an attacker to inject or manipulate SQL queries in the back-end database.
Upgrade to any version after 0.7, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
