{"cve":"CVE-2024-39683","nvd":{"published":"2024-07-03T20:15:04.840","modified":"2026-06-17T07:42:27.903","status":"Analyzed","description":"ZITADEL is an open-source identity infrastructure tool. ZITADEL provides users the ability to list all user sessions of the current user agent (browser). Starting in version 2.53.0 and prior to versions 2.53.8, 2.54.5, and 2.55.1, due to a missing check, user sessions without that information (e.g. when created though the session service) were incorrectly listed exposing potentially other user's sessions. Versions 2.55.1, 2.54.5, and 2.53.8 contain a fix for the issue. There is no workaround since a patch is already available.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-200"],"references":["https://discord.com/channels/927474939156643850/1254096852937347153","https://github.com/zitadel/zitadel/commit/4a262e42abac2208b02fefaf68ba1a5121649f04","https://github.com/zitadel/zitadel/commit/c2093ce01507ca8fc811609ff5d391693360c3da","https://github.com/zitadel/zitadel/commit/d04f208486a418a45b884b9ca8433e5ad9790d73","https://github.com/zitadel/zitadel/issues/8213"],"products":["zitadel:zitadel"],"source":"nvd","synced_at":"2026-10-19T21:52:00.836172422+00:00"},"epss":{"cve":"CVE-2024-39683","score":0.00609,"percentile":0.4919,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-cvw9-c57h-3397","url":"https://osv.dev/vulnerability/GHSA-cvw9-c57h-3397","summary":"ZITADEL Vulnerable to Session Information Leakage","modified":"2026-09-10T03:50:16.585195161Z","packages":[{"ecosystem":"Go","name":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","ranges":[">=2.0.0 <2.53.8"],"fixed":["2.53.8"]},{"ecosystem":"Go","name":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","ranges":[">=2.54.0 <2.54.5"],"fixed":["2.54.5"]},{"ecosystem":"Go","name":"github.com/zitadel/zitadel","purl":"pkg:golang/github.com/zitadel/zitadel","ranges":[">=2.55.0 <2.55.1"],"fixed":["2.55.1"]}]},{"id":"GO-2024-2968","url":"https://osv.dev/vulnerability/GO-2024-2968","summary":"ZITADEL Vulnerable to Session Information Leakage in github.com/zitadel/zitadel","modified":"2024-07-09T19:59:28.156514Z","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).
