{"cve":"CVE-2024-41952","nvd":{"published":"2024-07-31T17:15:10.597","modified":"2026-06-17T07:48:31.033","status":"Analyzed","description":"Zitadel is an open source identity management system. ZITADEL administrators can enable a setting called \"Ignoring unknown usernames\" which helps mitigate attacks that try to guess/enumerate usernames. If enabled, ZITADEL will show the password prompt even if the user doesn't exist and report \"Username or Password invalid\". Due to a implementation change to prevent deadlocks calling the database, the flag would not be correctly respected in all cases and an attacker would gain information if an account exist within ZITADEL, since the error message shows \"object not found\" instead of the generic error message. This vulnerability is fixed in 2.58.1, 2.57.1, 2.56.2, 2.55.5, 2.54.8, and 2.53.9.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-203"],"references":["https://github.com/zitadel/zitadel/commit/0ab0c645ef914298c343fa39cccb1290aba48bf6","https://github.com/zitadel/zitadel/commit/3c7d12834e32426416235b9e3374be0f4b9380b8","https://github.com/zitadel/zitadel/commit/5c2526c98aafd1ba206be2fa4291b1d24c384f6d","https://github.com/zitadel/zitadel/commit/8565d24fd8df5bd35294313cfbfcc2e15aea20e9","https://github.com/zitadel/zitadel/commit/b0e71a81ef39667ce2a149ce037c1ca0edbe059d"],"products":["zitadel:zitadel"],"source":"nvd","synced_at":"2026-10-19T21:53:51.317825789+00:00"},"epss":{"cve":"CVE-2024-41952","score":0.00633,"percentile":0.50345,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-567v-6hmg-6qg7","url":"https://osv.dev/vulnerability/GHSA-567v-6hmg-6qg7","summary":"ZITADEL \"ignoring unknown usernames\" vulnerability","modified":"2025-07-08T16:39:58Z","packages":[{"ecosystem":"Go","name":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","ranges":[">=2.53.0 <2.53.9"],"fixed":["2.53.9"]},{"ecosystem":"Go","name":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","ranges":[">=2.54.0 <2.54.8"],"fixed":["2.54.8"]},{"ecosystem":"Go","name":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","ranges":[">=2.55.0 <2.55.5"],"fixed":["2.55.5"]},{"ecosystem":"Go","name":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","ranges":[">=2.56.0 <2.56.2"],"fixed":["2.56.2"]},{"ecosystem":"Go","name":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","ranges":[">=2.57.0 <2.57.1"],"fixed":["2.57.1"]},{"ecosystem":"Go","name":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","ranges":[">=2.58.0 <2.58.1"],"fixed":["2.58.1"]},{"ecosystem":"Go","name":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","ranges":[">=0.0.0-20230609131415-dafa8ab4dfe8 <0.0.0-20240731122357-a1d24353db4d"],"fixed":["0.0.0-20240731122357-a1d24353db4d"]},{"ecosystem":"Go","name":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","ranges":[">=1.80.0-v2.20.0.20230609131415-dafa8ab4dfe8 <1.80.0-v2.20.0.20240731122357-a1d24353db4d"],"fixed":["1.80.0-v2.20.0.20240731122357-a1d24353db4d"]}]},{"id":"GO-2024-3014","url":"https://osv.dev/vulnerability/GO-2024-3014","summary":"ZITADEL \"ignoring unknown usernames\" vulnerability in github.com/zitadel/zitadel","modified":"2024-08-06T22:27:07.255358Z","packages":[{"ecosystem":"Go","name":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","ranges":["all versions"],"fixed":[]}]}],"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).
