CVE-2025-27792 Details
Description
Opal is OBiBa’s core database application for biobanks or epidemiological studies. Prior to version 5.1.1, the protections against cross-site request forgery (CSRF) were insufficient application-wide. The referrer header is checked, and if it is invalid, the server returns 403. However, the referrer header can be dropped from CSRF requests using `<meta name="referrer" content="never">`, effectively bypassing this protection. Version 5.1.1 contains a patch for the issue.
A cross-site request forgery (CSRF) vulnerability exists in OBiBa Opal versions prior to 5.1.1. The application-wide protections against CSRF were inadequate, allowing attackers to bypass the referrer header check, which is the primary defense mechanism. This bypass can be achieved by using a specific meta tag to drop the referrer header from CSRF requests, effectively circumventing the application's CSRF protection. The vulnerability allows for state-changing actions to be performed without proper authorization.
Users are advised to update to OBiBa Opal version 5.1.1 or later, where this vulnerability has been patched.
