CVE-2024-0892: CWE-352 Cross-Site Request Forgery (CSRF) in vberkel Schema App Structured Data
The Schema App Structured Data plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.2.0. This is due to missing or incorrect nonce validation on the MarkUpdate function. This makes it possible for unauthenticated attackers to update and delete post metadata via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
AI Analysis
Technical Summary
CVE-2024-0892 is a CSRF vulnerability in the Schema App Structured Data WordPress plugin (versions ≤ 2.2.0). The issue arises from missing or incorrect nonce validation in the MarkUpdate function, enabling attackers to craft forged requests that, if executed by an authenticated site administrator, can update or delete post metadata without proper authorization. The vulnerability requires user interaction (UI:R) and does not impact confidentiality or availability but can cause integrity loss of post metadata.
Potential Impact
An attacker can exploit this vulnerability by tricking a site administrator into clicking a malicious link, causing unauthorized modification or deletion of post metadata. While the confidentiality and availability of the system are not affected, the integrity of post metadata can be compromised. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, administrators should exercise caution with links and requests that could trigger the MarkUpdate function. Implementing additional nonce validation or CSRF protections at the application level may help mitigate risk.
