  "details": "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 `\u003cmeta name=\"referrer\" content=\"never\"\u003e`, effectively bypassing this protection. Version 5.1.1 contains a patch for the issue.",
