Executive brief
myCred is a popular WordPress plugin used to manage points, rewards, and loyalty programs on websites. A security flaw in versions 3.0.3 and earlier allows users with basic 'Subscriber' accounts to perform actions they should not be authorized to do. This could lead to unauthorized changes to the points system or other plugin settings, potentially impacting the integrity of the site's reward program.
Technical details
The myCred plugin for WordPress (versions <= 3.0.3) contains a broken access control vulnerability classified as CWE-862 (Missing Authorization). The flaw exists because the plugin fails to properly validate user permissions or implement sufficient nonce checks on certain functions. An attacker authenticated with low-level 'Subscriber' privileges can exploit this over the network to execute higher-privileged actions, specifically impacting the integrity of the system's data. The issue is resolved in version 3.0.4.
