Versions 2.44.0 through 3.4.4 and 4.0.0-rc.1 through 4.7.1 disclose the total number of instance users to authenticated users, regardless of their specific permissions. While this does not leak individual user data or PII, disclosing the total user count via the totalResult field constitutes an information disclosure vulnerability that may be sensitive in certain contexts. This issue is fixed in versions 3.4.5 and 4.7.2.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":5.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-497"],"references":["https://github.com/zitadel/zitadel/commit/826039c6208fe71df57b3a94c982b5ac5b0af12c","https://github.com/zitadel/zitadel/security/advisories/GHSA-f4cf-9rvr-2rcx"],"products":["zitadel:zitadel"],"source":"nvd","synced_at":"2026-10-19T22:16:40.427100871+00:00"},"epss":{"cve":"CVE-2025-67717","score":0.00222,"percentile":0.12728,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-f4cf-9rvr-2rcx","url":"https://osv.dev/vulnerability/GHSA-f4cf-9rvr-2rcx","summary":"Zitadel Discloses the Total Number of Instance Users","modified":"2026-02-03T03:13:16.613237Z","packages":[{"ecosystem":"Go","name":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","ranges":[">=4.0.0-rc.1 <4.7.2"],"fixed":["4.7.2"]},{"ecosystem":"Go","name":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","ranges":[">=2.44.0 <3.4.5"],"fixed":["3.4.5"]},{"ecosystem":"Go","name":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","ranges":["<1.80.0-v2.20.0.20251210121356-826039c6208f"],"fixed":["1.80.0-v2.20.0.20251210121356-826039c6208f"]}]},{"id":"GO-2025-4227","url":"https://osv.dev/vulnerability/GO-2025-4227","summary":"Zitadel Discloses the Total Number of Instance Users in github.com/zitadel/zitadel","modified":"2025-12-15T20:41:12.202405Z","packages":[{"ecosystem":"Go","name":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","ranges":["<1.80.0-v2.20.0.20251210121356-826039c6208f"],"fixed":["1.80.0-v2.20.0.20251210121356-826039c6208f"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
