{"id":"CVE-2025-15039","url":"https://www.cyber-defence.io/tools/cve/CVE-2025-15039","generatedAt":"2026-10-28T02:17:55.872Z","title":"This allows an attacker to bypass intermediate authentication challenges by exploiting how the script handles callbacks and re-execution of authentication steps.","description":"The Conditional Authentication (Adaptive Authentication) script does not correctly enforce the completion of all required authentication steps when a specific multi-step pattern involving certain authenticators is configured. This allows an attacker to bypass intermediate authentication challenges by exploiting how the script handles callbacks and re-execution of authentication steps.\n\nSuccessful exploitation allows a malicious actor to gain unauthorized access to a targeted user account. This vulnerability can only be exploited when all of the following conditions are met: the application login flow contains a specific secondary authenticator, the Conditional Authentication script is configured with particular event callbacks and re-executes an authentication step, the targeted user has one of the impacted authenticators enrolled, and the attacker successfully completes any preceding authentication steps.","published":"2026-08-06T08:16:29.000Z","lastModified":"2026-09-29T14:10:00.000Z","status":"Analyzed","sourceIdentifier":"ed10eef1-636d-4fbe-9993-6890dfa878f8","cvss":{"version":"3.1","score":9.4,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L"},"cwe":["CWE-693"],"affected":["wso2/api control plane","wso2/api manager","wso2/identity server","wso2/identity server as key manager","wso2/open banking am","wso2/open banking iam","wso2/open banking km","wso2/traffic manager","wso2/universal gateway"],"epss":{"score":0.00668,"percentile":0.51615,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.67%).
