Affected versions of the module do not properly protect against SAML assertion replay in IdP-initiated authentication flows. This could allow unauthenticated remote attackers to gain unauthorized access to the application by replaying a valid SAML response.","cvssScore":6.8,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N","cwes":["CWE-294"],"vendors":[],"products":[],"references":[{"url":"https://cert-portal.siemens.com/productcert/html/ssa-137528.html","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
