CVE-2024-0590: Microsoft Clarity

Medium severity, CVSS 6.1. EPSS: 1.3% chance of exploitation in the next 30 days.

The Microsoft Clarity plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 0.9.3. This is due to missing nonce validation on the edit_clarity_project_id() function. This makes it possible for unauthenticated attackers to change the project id and add malicious JavaScript via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Affected products

• Microsoft Clarity: before 0.9.4 (fixed in 0.9.4)
