Multiple SQL injection vulnerabilities in DropAFew before 0.2.1 allow remote attackers to execute arbitrary SQL commands via the (1) id parameter in the delete action in (a) search.php or (b) search-pda.php, or the (2) calories parameter in a save action in editlogcal.php.

DropAFew before 0.2.1 does not require authorization for certain privileged actions, which allows remote attackers to (1) view the logged calorie information of arbitrary users via the id parameter in editlogcal.php, (2) add arbitrary links via links.php, or (3) create arbitrary users via newaccount2.php.
