Prior to 4.6.0, 3.4.3, and 2.71.18, an attacker can perform an online brute-force attack on OTP, TOTP, and passwords. While Zitadel allows preventing online brute force attacks in scenarios like TOTP, Email OTP, or passwords using a lockout mechanism. The mechanism is not enabled by default and can cause a denial of service for the corresponding user if enabled. Additionally, the mitigation strategies were not fully implemented in the more recent resource-based APIs. This vulnerability is fixed in 4.6.0, 3.4.3, and 2.71.18.","state":0,"publishedAt":"2025-10-29T18:36:15.39+00:00","modifiedAt":"2025-10-30T14:53:53.184+00:00","affected":[{"ecosystem":"Vendor product","name":"zitadel","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"zitadel\",\n                    \"product\": \"zitadel\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 4.0.0-rc.1, < 4.6.0\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 3.0.0-rc.1, < 3.4.3\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.0.0, < 2.71.18\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":7.7,"severity":"HIGH"}],"references":["https://github.com/zitadel/zitadel/security/advisories/GHSA-xrw9-r35x-x878","https://github.com/zitadel/zitadel/commit/b8db8cdf9cc8ea13f461758aef12457f8b7d972a"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-64102","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-64102","identifiers":["CVE-2025-64102"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
