An EPSS score is not available, and the vulnerability is not listed in the CISA KEV catalog. The problem is triggered by sending an HTTP request that contains a crafted return_id parameter, which is then reflected in the page without validation. Exploitation requires a user to access a page that processes the return_id value, so the attack vector is remote web application with user interaction. The impact is confined to the client\u2019s browser, but because it is a non\u2011disabling XSS, it may be leveraged for malicious client\u2011side operations."}}}}, "created": "2026-03-20T08:54:27.960525+00:00", "updated": "2026-03-20T10:43:55.786277+00:00", "vendors": ["suitecrm", "suitecrm$PRODUCT$suitecrm"]}
