What the vulnerability does
The Time Sheets plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.1.3. This is due to missing or incorrect nonce validation on several endpoints. This makes it possible for unauthenticated attackers to perform a variety of actions 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
Time Sheets versions 2.1.3 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 site administrator, performs unwanted actions within the Time Sheets application without the administrator'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 in Time Sheets on behalf of a logged-in administrator without their consent.
Potential impact on your site
An attacker can modify Time Sheets data or settings by tricking your administrators into visiting a malicious link.
