What the vulnerability does
The Purchase and Expense Manager plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.1.2. This is due to missing nonce validation on the 'sup_pt_handle_deletion' function. This makes it possible for unauthenticated attackers to delete arbitrary purchase records via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Explanation of Vulnerability in Simple Terms
Purchase and Expense Manager versions 1.1.2 and earlier are vulnerable to cross-site request forgery (CSRF) attacks. An attacker can craft a malicious webpage that, when visited by a logged-in user, performs unwanted actions within the application without the user's knowledge or consent. The vulnerability requires user interaction—the victim must visit the attacker's page while authenticated.
What an attacker can do
Perform unwanted actions (create, modify, or delete records) on behalf of a logged-in user without their knowledge.
Potential impact on your site
Users' data and settings can be altered by attackers through malicious webpages, potentially leading to unauthorized transactions or configuration changes.
Conditions required to exploit
User must be logged into the application and visit an attacker-controlled webpage.
