If a user has set up MFA without this requirement, Zitadel would consider single factor auhtenticated sessions as valid as well and not require multiple factors. Bypassing second authentication factors weakens multifactor authentication and enables attackers to bypass the more secure factor. An attacker can target the TOTP code alone, only six digits, bypassing password verification entirely and potentially compromising accounts with 2FA enabled. This vulnerability is fixed in 4.6.0, 3.4.3, and 2.71.18.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.7,"severity":null}],"references":["https://github.com/zitadel/zitadel/security/advisories/GHSA-cfjq-28r2-4jv5","https://github.com/zitadel/zitadel/commit/b284f8474eed0cba531905101619e7ae7963156b"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2025-36696","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 29, 2025, 6:43:46 PM","dateUpdated":"Oct 30, 2025, 2:51:19 PM"},"relatedAdvisories":[{"id":"openSUSE-SU-2025:15710-1","title":"govulncheck-vulndb-0.0.20251105T184115-1.1 on GA media","vulnerabilityIds":["CVE-2016-11063","CVE-2016-11066","CVE-2016-11067","CVE-2016-11068","CVE-2016-11069","CVE-2016-11070","CVE-2016-11071","CVE-2016-11072","CVE-2016-11073","CVE-2016-11074","CVE-2016-11075","CVE-2016-11076","CVE-2016-11077","CVE-2016-11078","CVE-2016-11079","CVE-2016-11080","CVE-2016-11081","CVE-2016-11082","CVE-2016-11083","CVE-2016-11084","CVE-2017-18872","CVE-2023-32199","CVE-2024-58269","CVE-2025-10545","CVE-2025-10678","CVE-2025-10954","CVE-2025-11374","CVE-2025-11375","CVE-2025-11579","CVE-2025-11621","CVE-2025-12044","CVE-2025-26625","CVE-2025-27093","CVE-2025-41410","CVE-2025-41443","CVE-2025-54286","CVE-2025-54287","CVE-2025-54288","CVE-2025-54289","CVE-2025-54290","CVE-2025-54291","CVE-2025-54293","CVE-2025-54469","CVE-2025-54470","CVE-2025-54471","CVE-2025-54499","CVE-2025-58073","CVE-2025-58075","CVE-2025-58356","CVE-2025-59043","CVE-2025-59048","CVE-2025-59530","CVE-2025-59836","CVE-2025-59937","CVE-2025-61141","CVE-2025-61524","CVE-2025-61581","CVE-2025-61688","CVE-2025-62156","CVE-2025-62157","CVE-2025-62375","CVE-2025-62506","CVE-2025-62513","CVE-2025-62705","CVE-2025-62714","CVE-2025-62725","CVE-2025-62820","CVE-2025-64101","CVE-2025-64102","CVE-2025-64103"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
